## 0.90-alpha1 (April 1, 2010)

### Breaking changes

#### Core

##### Extensibility

- Deprecated NAnt.Core.Element.InitializeElement(XmlNode) and NAnt.Core.Task.InitializeTask(XmlNode) in favor of NAnt.Core.Element.Initialize(). This was done to discourage direct access to the XML node that was used to initialize the construct.

#### Tasks

##### <script>

As of this release, only the following namespaces are imported by default:

- System
- System.Collections
- System.Collections.Specialized
- System.IO
- System.Text
- System.Text.RegularExpressions
- NAnt.Core
- NAnt.Core.Attributes

Starting from this release, only `NAnt.Core` and `mscorlib` will be referenced by default.

In previous releases, all loaded assemblies would implicitly be referenced.

### Bug fixes

#### Extensibility

##### DataTypeBaseBuilder / FilterBuilder / TaskBuilder

Changes to constructors break backward compatibility (bug 2782705).

#### Expressions

##### Identifiers

Identifiers containing a dot or backslash are falsely rejected.

#### Framework support

- Added support for Windows SDK 6.1 (bug #1986551).
- Added support for Windows SDK 7.0

#### Tasks

##### <echo>

A newline is implicitly added when writing a message to a file (bug #2807728).

##### <echo>

When "output" parameter is specified, standard output is redirected properly. (bug #1010223).

##### ExternalProgramBase

The value of `UseRuntimeEngine` is not respected when overriden by derived classes (bug #1850383).

##### <move>

When source file is newer than destination file, then an error is reported if "overwrite" is not set to true.

##### <solution>

Solution Folders result in build failure (bug #1732361).

##### <xmlpeek>

"verbose" feature is now worked as documented (bug #1911292).

##### <zip>

Improved backward compatibility with older unzip implementations.

#### Types

                <property name="nant.settings.currentframework" value="${framework}" />
                <call target="${framework}" />
            </foreach>
        </target>

        <target name="build">

        </target>

##### framework::get-version()

Gets the version of the current target framework.

##### platform::is-windows()

Return a value indicating whether NAnt is running on Windows.

#### Tasks

When installing NAnt from source on Unix (using make install), a nant.pc is now installed in $prefix/lib/pkgconfig.

##### DESTDIR

To allow for staged installs, our makefile now also supports the DESTDIR variable:

        $ make DESTDIR=/tmp/local install

#### Functions

                    <include name="Cegeka.HealthCare.Common.dll" />
                    <include name="Cegeka.HealthCare.DocGen.dll" />
                    <include name="Cegeka.HealthCare.Util.dll" />
                </assemblies>
            </test>

## 0.86-beta1 (December 8, 2007)

### Breaking changes

#### Core

##### nant.tasks properties

Prior to NAnt 0.85, build authors would use a "nant.tasks.*" property to check whether a given task was available.

With the introduction of expression support in NAnt 0.85, we provided a more powerful alternative through the task::exists function.

As of this release, the "nant.tasks.*" properties are therefore no longer set by NAnt.

##### nant.failure

Removed support for the "nant.failure" property to set the target that should be executed when the build fails.

This property was deprecated in NAnt 0.83 in favor of the "nant.onfailure" attribute.

As of this release, setting the "nant.failure" attribute will no longer have any effect.

#### Expressions

##### = operator

In NAnt 0.85, support for the '=' operator to check for equality was deprecated in favor of the '==' operator.

As from this release, the '=' operator is no longer recognized.

#### Tasks

##### <style>

- Removed support for <param> child element, which was deprecated in NAnt 0.84 in favor of a <parameters> element.

### Bug fixes

#### Core

##### MailLogger

- If "MailLogger.smtp.username", "MailLogger.smtp.port" or "MailLogger.smtp.enablessl" are set, messages must be delivered using the SMTP protocol over the network. [.NET 1.1 or higher]

##### Response File

- Quoted arguments are not parsed correctly from response files (bug #1736526).

##### Document Type Definition

- Executing a project with a DTD can lead to an internal error. (bug #1809994).

#### Framework support

##### Mono/Cygwin

- In Cygwin, the directory containing the Mono configuration files was not correctly constructed from pkg-config info, leading to errors when running applications that use System.Configuration.

#### Tasks

##### <call>

- Target is not re-executed if "cascade" is false (bug #1474159).

##### <csc>

- Satellite assemblies are not signed when signing key is specified using "keyfile" attribute (bug #1587739).

##### <exec>

- Empty lines written to standard output or standard error by external program are ignored.

##### <resgen>

- If the embedded resource compiler for the target framework does not support assembly references, then copy both the compiler and related files (based on pattern matching) to the intermediary compile directory (bug #1591991).

##### <solution>

- Visual C++
  - Custom build steps are not supported (bug #1082374).
  - Unexpected error when name of project configuration differs from solution configuration (bug #1607209).

#### Third-Party

##### #ziplib

- Files with a compressed size of over 4GB cannot be added to zip archive (bug #1698336).

#### Types

##### <fileset>

- Case differences are not always ignored on a case-insensitive filesystem (bug #1776101).
- Pattern mathing for files in the root directory of a volume is always case-sensitive (bug #1761377).

### Additions

#### Expressions

##### Version operators

Introduced support for relational operators between version values.

#### Framework support

##### Tool paths

Since NAnt 0.84, task authors have been able to specify the location of the command-line tool by applying a `ProgramLocationAttribute` to classes deriving from `ExternalProgramBase`.

The `ProgramLocationAttribute` allows task authors to specify whether the tool is located in the framework directory (eg. C:\WINDOWS\Microsoft.NET\Framework\v1.1.4432) or the SDK directory (eg. C:\Program Files\Microsoft Visual Studio .NET 2003\SDK\v1.1) without actually having to deal with the complexity of knowing the actual path to these directories (for each supported framework).

In NAnt 0.86, we've taken this one step further. Each defined framework now has a (ordered) list of directories that can be scanned to locate a framework tool. The list of directories can be easily tuned for each framework by modifying the <tool-paths> nodes in the NAnt configuration file.

An example of such a node for the Mono 3.5 profile:

        <tool-paths>
            <directory name="${path::combine(prefix, 'lib/mono/3.5')}" />
            <directory name="${path::combine(prefix, 'lib/mono/2.0')}" />
            <directory name="${path::combine(prefix, 'lib/mono/1.0')}" />
        </tool-paths>

The directories configured in the <tool-paths> node of the current target framework will be scanned in the order in which they are defined.

The tool paths are implicitly used when a given tool cannot be located on the location specified by the `ProgramLocationAttribute`. As such, this only applies to tasks deriving from `ExternalProgramBase`.

To expose this functionality to build authors, we've added a framework::get-tool-path function that can be used to search for a given tool.

For example:

        <exec program="${framework::get-tool-path('gacutil.exe')}" managed="strict">
            <arg value="/i" />
            <arg file="Cegeka.HealthFramework.dll" />
        </exec>

##### Strict execution

Introduced support for forcing a managed application to run on the currently targeted CLR.

This was previously only possible by modifying the <startup> section of the application configuration file or by using constructs specific to each CLR (eg. using COMPLUS_VERSION environment variable for the MS CLR), which made build scripts non-portable.

Developers extending NAnt, can now control this by setting the `Managed` property for tasks deriving from `ExternalProgramBase`.

For build authors, forcing a managed application to run on a specific version of a CLR can be done by setting the "managed" attribute of `<exec>` to strict.

For example:

        <exec program="nunit-console.exe" managed="strict">
            <arg value="/noshadow" />
            <arg file="Cegeka.HealthFramework.Tests.dll" />
        </exec>

##### .NET Framework 3.5

Support for targeting .NET Framework 3.5 and Mono 3.5 Profile is now available.

Note: this does not apply to the `<solution>` task.

##### Silverlight 2.0

Added experimental support for targeting Silverlight 2.0 and Moonlight 2.0.

Note: this does not apply to the `<solution>` task.

#### Types

##### <patternset>

Defines a set of patterns, mostly used to include or exclude certain files.

Patterns can be grouped to sets, and later be referenced by their `id`.

For example:

        <patternset id="binaries">
            <include name="bin/**/*" />
            <exclude name="bin/*.tmp" />
        </patternset>

        <patternset id="docs">
            <include name="requirements/**/*" />
            <exclude name="design/**/*.doc" />
        </patternset>

        <patternset id="client.sources">
            <include name="client/**/*.cs" />
            <exclude name="client/**/*.vb" />
        </patternset>

        <patternset id="server.sources">
            <include name="server/**/*.cs" />
            <exclude name="server/**/*.vb" />
        </patternset>

        <patternset id="sources">
            <patternset refid="client.sources" />
            <patternset refid="server.sources" />
        </patternset>

        <target name="deploy">
            <copy todir="${dist.path}">
                <fileset basedir="${build.path}">
                    <patternset refid="binaries" />
                    <patternset refid="docs" />
                    <patternset refid="sources" />

                    <exclude name="**/*.sdf" />
                </fileset>
            </copy>
        </target>

### Changes

##### Performance

Initial start-up time and project initialization have been reduced dramatically by lazy configuration of supported target frameworks.

#### Framework support

##### .NET Compact Framework 2.0

Compiler options that were introduced in .NET Framework 2.0 are now also available when targeting .NET Compact Framework 2.0.

##### #ziplib

- Upgraded to v0.85.1 which, amongst other things, adds support for ZIP64.

#### Types

##### <assemblyfileset>

The reference assemblies of a given target framework are no longer limited to the assemblies in, what is known as, the framework assembly directory.

Instead, these are now defined using one or more <reference-assemblies> filesets in the <framework> node of the NAnt configuration file.

##### <fileset>

Added a "casesensitive" attribute to control whether pattern matching must be case-sensitive.

The default is true on Unix and false on on other platforms.

##### Define types in task containers.

Global types can now be (re)defined in task containers (such a `<if>` , `<foreach>`).

For example:

        <project name="container-type" default="build">
            <if test="${platform::is-win32()}">
                <fileset id="sources">

                </fileset>
            </if>
            <if test="${platform::is-unix()}">
                <fileset id="sources">
                    <include name="**/*.cs" />
                    <!-- exclude Win32-specific classes -->
                    <exclude name="**/Win32/*.cs" />
                </fileset>
            </if>
            <target name="build">
                <csc output="IvsController.dll">
                    <sources refid="sources" />
                    <references>
                        <include name="System.dll" />
                        <include name="System.Data.dll" />
                        <include name="System.Xml.dll" />
                    </references>
                </csc>

- Added a "cascade" attribute to allow calling a single task without cascading all the dependencies. (bug #1077323 ).

##### <solution>

- A relative path specified in the AssemblyKeyFile attribute must be resolved using either the solution directory or the intermediate output directory.
- Configurations containing dashes are skipped (bug #1184173).
- Check for existance of specified solution file is performed even if task is not to be executed (bug #1178810).
- Project configurations with names that do not match the solution configuration are skipped (bug #947214).
- Projects are not always properly excluded (bug #1143845 and #1182510).
- Stack overflow in case of circular project references (bug #1145670).
- BaseAddress not correctly passed to compilers (bug #1164709).
- Project dependencies that are no longer included in the solution file result in a circular dependency error.
- VB.NET
  - Referencing the same assembly multiple times results in an ambiguous reference (bug #1178862).

### Changes

#### Core

##### MailLogger

- Added "MailLogger.body.encoding" property to allow the encoding of the body of the message to be set.

##### Response File

- NAnt now supports the use of a response file. Passing @<file> on the command line will cause the contents of <file> to be read as part of the command line. Multiple @<file> arguments may be used.

##### XmlLogger

- Project, target and task timing information is now output in a <duration> element in milliseconds (patch #1122583)

#### Tasks

##### <csc> / <vbc> / <vjc>

##### <lib>

- Add "moduledefinition" attribute.

##### <midl>

- "tlb" attribute is no longer required.

### Developer information

#### API

##### FileSetAttribute

The NAnt.Core.Attributes.FileSetAttribute is obsolete. Task developers should use the NAnt.Core.Attributes.BuildElementAttribute instead:

For example:

        [FileSetBuildElement("fileset")]
        public FileSet CopyFileSet {
            get { return _fileset; }
            set { _fileset = value; }
        }

## 0.85-rc 2 (February 12, 2005)

### General changes

##### Building NAnt

- The source distribution of NAnt no longer contains pre-built binaries to build a full version of NAnt. Instead, we now include GNU Make and NMake make files to build a bootstrap version of NAnt, which is then used to build the full version of NAnt. More information is available here.

##### License

#### Types

##### <import>

- The "name" attribute of the `<import>` element has been deprecated, and replaced by a "namespace" attribute. This change affects the following tasks: `<asminfo>`, `<script>` and `<vbc>`.

## 0.85-rc 1 (November 28, 2004)

### Framework support

- NAnt 0.85 adds support for the following frameworks (both as runtime and as target framework):
  - Mono (both 1.0 and 2.0 profile)
  - .NET 2.0 Beta 1
- By default, NAnt will now target the framework on which its running. For example, if NAnt is running on .NET 2.0, the assemblies built using the `<csc>` task will target .NET 2.0. Previous versions of NAnt would target .NET 1.0 by default.
- Information on how to override the target framework, can be found here.

### Breaking changes

- In previous version of NAnt, the `<arg>` element (used by, for example, the `<exec>` task) would automatically add quotes for both "file" and "value" attributes in the command line generated by the task. That automatic quoting has been removed for "value" attributes (but not for "file" attributes). This change may break build files that assume that both arguments specified using the "file" and "value" attributes will automatically be quoted.
- Overwriting of read-only properties in tasks other than the <property> task will now result in a build failure. Previous versions of NAnt would silently ignore an update of a read-only property.
- The `<nunit2>` task been updated to support NUnit 2.2. Assemblies built using previous versions of NUnit should either be rebuilt using NUnit 2.2 or a binding redirect should be configured in the application configuration file of the test assembly.

### General changes

- Improved error reporting when invalid values are specified for attibutes representing files or directories.
- This release of NAnt introduces support for expressions. More information is available here.
- FilterChain support has been introduced to NAnt.
- Enums that are used in tasks or types now have their own doc pages.
- The default logger will now also output the number non-fatal errors and warnings.
- Output of the `XmlLogger` is now buffered until build has finished, and `XmlLogger` can now also be used as a listener.
- Added support for wild targets.
- Lots of built-in properties have been deprecated, and replaced by functions. More information is available here.
- NAnt will now report unknown attributes and child elements when initializing build elements.

### Commandline changes

- Added "-e[macs]" option, which can be used to produce logging information without adornments.
- Added "-ext[ension]" option to allow loading of external assemblies. As a result, third party loggers or listeners no longer have to reside in the NAnt bin directory or the GAC in order to be used by NAnt.
- Deprecated -[defaultframewor]k option in favor of -t[argetframework].

### New Tasks

#### <aximp>

The compiled resource files will not be removed when the task finishes, by doing this resource files will now only be recompiled if the compiled resource file in the object directory is no longer up-to-date. This matches the behaviour of VS.NET.
- Added support for deploying App.config to output directory.

#### <sysinfo>

- If "failonerror" is false, the <sysinfo> task will output a warning message in the build log when a certain environment variable cannot be exposed as a property (because of, for example, more strict naming rules for properties) and continue processing other environment variables. In previous versions of NAnt, execution of the <sysinfo> task would halt on the first error.

#### <vbc>

- Added support for suppressing specific warnings using the `<nowarn>` child element. [.NET 2.0 or higher]
- Added support for suppressing/reporting specific warnings as errors using the `<warnaserror>` child element. [.NET 2.0 or higher]

## 0.84-rc 1 (December 6, 2003)

### Breaking changes

Some existing build scripts may stop working now or in the next release due to the following changes:

- The NAntContrib binaries are no longer included in the NAnt distribution package. The NAntContrib distribution package can now be obtained here.
- The `<call>` task now executes the given target and all its dependencies. In previous versions of NAnt only the target itself would be executed.
- The `todir` attribute of the `<copy>` and `<move>` tasks no longer defaults to the project base directory. It must now be set explicitly.
- The `force` attribute of the `<call>` task has been deprecated and has no longer any effect. The `<call>` task will now always execute the specified target, regardless of the fact that this target has already been executed before.
- The string-based `files` and `attachments` attributes of the `<mail>` task have been replaced by fileset support.
- In previous versions of NAnt, the documentation stated that a target identified by the `nant.onfailure` property would be executed when the build fails. However, NAnt actually executed a target identified by the `nant.failure` property (if available). This has now been corrected and the old syntax (`nant.failure`) is now deprecated.
- The `<param>` element of the `<style>` task has been deprecated in favor of a `<parameters>` collection with nested `<parameter>` elements. The `<parameter>` element now also supports a `namespaceuri`, `if` and `unless` attribute. See the documentation of the `<style>` task for more information.
- In previous versions of NAnt, the `Plain` formatter was implicitly added in the `<nunit2>` task. In NAnt 0.8.4, the `Plain` formatter will only implicitly be added if no other formatters are specified. In this case, a warning message will be output to the build log encouraging build authors to explicitly add this formatter for forward compatibility. In future versions of NAnt, the `Plain` formatter will no longer implicitly be added.
- The nested `<param>` child element of the `<style>` task has been deprecated in favor of a nested `<parameters>` collection.

### General changes

- The user documentation has been overhauled. Nested elements are more clearly documented, documentation has been added for element types such as filesets and credentials, and the overall format is slightly cleaner and easier to use.
- Improved bootstrapping NAnt on linux. Now supports Mono 0.28.
- Localization support has been improved in the `<csc>`, `<jsc>`, `<vbc>` and `<vjc>` tasks: when dynamixprefix is set to "true" and prefix is set to the root namespace of the assembly for the nested `<resources>` element, the compiler tasks will now compile resources with IDs matching these generated by VS.NET. Support for the generation of satellite assemblies was also added to these tasks.
- On systems with both the .NET Framework 1.0 and .NET Framework 1.1 installed, NAnt will now execute on the .NET Framework 1.1 by default. Note, the default target framework has remained unchanged, and is still .NET Framework 1.0.

### New Tasks

#### <asminfo>

- Moved from NAntContrib to NAnt, and was rewritten to support multiple code languages and attribute types.

#### <servicecontroller>

- Allows a Windows service to be controlled (started, stopped, ...).

#### <delay-sign>

### Task changes

#### <call>

- The `<call>` task now executes the given target and all its dependencies. In previous versions of NAnt only the target itself would be executed.

- Deprecated the `ignoreerrors` attribute in favor of the `failonerror` attribute.
- Added `timeout` attribute to allow length of time to wait for a response or the request to timeout to be specified.

#### <if>

- Added `<uptodatefiles` child element for uptodate fileset support.
- `<if uptodatefile="...">` now behaves as documented, meaning that nested tasks will only be executed if the file specifies in the uptodatefile attribute actually exists and the file specified in the `uptodatefile` attribute is more recent or the same lastwritetime than the file(s) specifies in the `comparefile` attribute and `<comparefiles>` fileset.

#### <include>

- A verbose message will now be output to the build log when a file is included multiple times. In previous versions of NAnt, this would cause a build failure.

#### <jsc>

- Added support for additional search directories to resolve assembly references through a nested `<lib>` element.

#### <mail>

- The string-based `files` and `attachments` attributes have been replaced by fileset support.

- Added `flatten` attribute to allow all matching files to be moved to a single directory.

#### <nant>

- Properties can now be added or overridden when calling a nested build using the new `<properties>` child element.
- `buildfile` is now a required attribute, which makes it harder to accidently write an infinitely looping build.

#### <nantschema>

#### <ndoc>

- Updated the `<ndoc>` task to using version 1.2 of NDoc.

#### <nunit2>

- Updated the `<nunit2>` task to use version 2.1 of NUnit.
- In previous versions of NAnt, the `Plain` formatter was implicitly added. In NAnt 0.8.4, the `Plain` formatter will only implicitly be added if no other formatters are specified. In this case, a warning message will be output to the build log encouraging build authors to explicitly add this formatter for forward compatibility. In future versions of NAnt, the `Plain` formatter will no longer implicitly be added.
- Added `outputdir` attribute for `<formatter>` element to control the directory where the test result file will be stored (if the `usefile` attribute is "true").

#### <property>

- Added `overwrite` attribute to the `<property>` task to control whether the value of the specified property should be overwritten when the property already exists.
- Added support for dynamic properties, meaning properties of which references to other properties are not expanded when the value is set.

#### <resgen>

- Added support for specifying a prefix to `<resgen>` task when using a fileset.

#### <solution>

- Added nested `<assemblyfolders>` fileset element that allows a set of folders to be set, that should be searched to resolve assembly references.
- By default, the Visual Studio.NET assembly folders will be searched to resolve assembly references. An `includevsfolders` attribute was added to control whether these folders should be searched for assembly references.
- Added `<excludeprojects>` fileset that allows a set of projects to be excluded.
- An `outputdir` attribute can now be specified, which overrides the directory where compiled targets will be placed.
- A nested `<webmap>` element was added that maps URL's of web projects to local path, thereby removing the need to configure the web server to allow access to these project files.
- Added support for Visual C++ projects.
- A large number of defect fixes and performance improvements have been applied.

#### <style>

- The nested `<param>` child element has been deprecated in favor of a nested `<parameters>` collection.

#### <touch>

- Fixed issue when files were included that were not located beneath the basedir of the fileset.
- Added `includeemptydirs` attribute to control whether empty directories should be included in the generated zip file.
- Fixed failure when no `basedir` for fileset was specified.
- Fixed failure when `basedir` of fileset is set to the root directory of a drive in Windows.

### API changes

- Added `ProgramLocationAttribute` that can be assigned to a task to indicate that it wraps an executable that is part of either the .NET Framework or the .NET Framework SDK, and have NAnt figure out the full path to the executable using the framework settings in the NAnt configuration file.
- `FileSetAttribute` has been deprecated. The `BuildElementAttribute` should be used instead.
- Added `FrameworkConfigurableAttribute` that can be assigned to a task attribute to allow the default values of that attribute to be configured from the framework configuration section in the NAnt configuration file for the currently active framework.

  This is the first release with Linux support, so please report any issues you encounter. The next release will be fully tested and documented on both Linux and Windows.
- New Tasks.
  - <cvs-checkout> task : Checkout source from CVS.
  - <cvs-update:> task : Update source from CVS.
  - <solution> task : compile .sln directly. In most cases, this means you no longer have to preprocess a solution with the slingshot tool. Supports both Visual Studio .NET and Visual Studio 2003.
- Changed tasks.
  See the section below for details.
- FileSet references.
  You can now define a named FileSet and refer to it anywhere a FileSet is used.

### API changes

- Namespace changes
  - "SourceForge" is no longer part of the NAnt namespaces.
  - Split classes up into Tasks and Types.
  - Task assemblies now have their own namespaces.
  - Removed Msft prefix from base classes.
- Logging framework changed
  - Refactored NAnt (build) logging system : moved to an event driven logging system, and allow thresholds to be set. The build outcome is now completely handled by the loggers.
  - Replaced the LogListener with an IBuildLogger interface for loggers and an IBuildListener interface for build listeners.
  - The ConsoleLogger is replaced by a DefaultLogger, which always logs to the console, and which can also be configured to log to a file (using the -logfile option).
  - The static Log class is removed and replaced by instance methods on the Project and Task classes. These instance methods actually fire events that get handled by the build logger and buid listeners.
  - Added a Level enum that is used to assign a priority (level) to a message. This allows messages to be filtered on their priority.
  - Added a strongly typed collection for the build listeners.
  - Updated all existing logging statements to use the new logging system instead of the static Log class. Assigned levels to the existing logging statements.
  - Added MailLogger that can be used to send the build results as an email, see xml docs for how its to be configured.
- Many, many style/structure/documentation fixes. More that are worth listing here.
- Fixed NUnit2 support for FileSets.
- Prevent warnings for using obsolete methods to allow NDoc Documenter.Nant to build on .NET 1.1 runtime.
- Nightly.xml no longer depends on NAntContrib tasks.
- Moved <mail> task and test back into core as its working fine on Linux now.
- New attribute-driven command-line parser.

### Command-line client changes

- Changed target back to the default argument.
- Moved company information (http://nant.sourceforge.net) from help text to logo banner.
- Added support for running default.build if there are multiple build files in a directory.
- Added support for collection-based command-line options, with the following restrictions :
  - property type should implement ICollection
  - collection should have an Add method with one parameter
  - parameter of the Add method should be strongly-typed
  - collection should have a default public constructor
  - the property should have a setter if the collection is not initialized (null reference)
- Fixed "bug" where ApplicationException would no longer be throw when no matching buildfile is found after searching the directory tree upwards.
- Updated short form of buildfile to -f.
- Added -q shortname for -quiet command-line option.
- Changed description of -indent command-line option.
- Added command-line option for adding build listeners.
- Updated xml documentation.
- Added command-line options for filtering build output (-debug and -quiet).
- Jarek's patch to allow setting of the default framework from the command line, fixes bug 729778.
- Always use identifier mono-1.0 for Mono framework, no use in always creating new framework configurations for every Mono release.

### Task changes

#### <exec>

- Added support for an environment optionset to the <exec> task.
- Fixed optionset so that it correctly returns optionvalues.
- Remove Timeout from ExecTask, make Timeout in ExternalProgramBase a task attribute and make it writable.

#### <vjc>

- Added attribute for setting the warninglevel (0-4).
- Added attribute for specifiying list of warnings that should be suppressed by the compiler.

- Fixed csc example.

#### <nantschema>

- Added makefile for building on Linux. Also a new bin directory for Linux specific binaries.

#### <mcs>

- Removed <mcs> task. the <csc> task in combination with the framework support should be used instead.

#### <nant>

- Fixed problem with basedir in nested <nant> build being incorrect if basedir="." is used.
- Have new project inherit the default framework from the current project.

#### <copy>

- Fix for <copy> task breakage on Linux.
- Reenabled File.SetAttributes on Mono build as bug #41999 has been fixed.

#### <if>

- Fixed logging bug with parenthesis instead of brace. Caused <if uptodate...> to fail erroneously.

#### <cl> and <link>

- On demand compile support for <link> and <cl> tasks.
- Added unit tests for the <cl> and <link> tasks.
- Moved Visual C++ related tasks into Win32Assemblies so it doesn't get built in a Mono/Linux build.

#### <fileset>

- Added support for FileSet references. Framework for making all types referencable but only implemented for FileSets right now.

#### <mail>

- Reenabled usage of StringWriter constructor with CultureInfo as this bug in Mono is fixed.
- No longer have empty strings as default.
