# <regsvcs>

[This is preliminary documentation and subject to change.]

Installs or removes .NET Services.

This tasks provides the same functionality as the `regsvcs` tool provided in the .NET SDK.

It performs the following actions:

- Loads and registers an assembly.
- Generates, registers, and installs a type library into a specified COM+ application.
- Configures services that are added programmatically to your class.

Refer to the .NET Services Installation Tool (Regsvcs.exe) for more information.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
assembly | file | The source assembly file. | True
action | ActionType | Defines the action to take with the assembly. The default is `FindOrCreate`. | False
application | string | Specifies the name of the COM+ application to either find or create. | False
componentsonly | bool | Configures components only; ignores methods and interfaces. The default is false. | False
existingapp | bool | Expect an existing application. The default is false. | False
existingtlb | bool | Uses an existing type library. The default is false. | False
noreconfig | bool | Do not reconfigure an existing target application. The default is false. | False
partition | string | Specifies the name or id of the COM+ application to either find or create. | False
tlb | file | Specifies the type library file to install. | False
failonerror | bool | Determines if task failure stops the build, or is just reported. The default is true. | False
if | bool | If true then the task will be executed; otherwise, skipped. The default is true. | False
timeout | int | The maximum amount of time the application is allowed to execute, expressed in milliseconds. Defaults to no time-out. | False
unless | bool | Opposite of `if`. If false then the task will be executed; otherwise, skipped. The default is false. | False
verbose | bool | Determines whether the task should report detailed build log messages. The default is false. | False

### Framework-configurable parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
exename | string | The name of the executable that should be used to launch the external program. | False
managed | ManagedExecution | Specifies whether the external program should be treated as a managed application, possibly forcing it to be executed under the currently targeted version of the CLR. | False
useruntimeengine | bool | Deprecated. Specifies whether the external program is a managed application which should be executed using a runtime engine, if configured. The default is false. | False

### Nested Elements:

#### <arg>

The command-line arguments for the external program.

Represents a command-line argument.

When passed to an external application, the argument will be quoted when appropriate. This does not apply to the `line` parameter, which is always passed as is.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
dir | directory | The value for a directory-based command-line argument; will be replaced with the absolute path of the directory. | False
file | file | The name of a file as a single command-line argument; will be replaced with the absolute filename of the file. | False
if | bool | Indicates if the argument should be passed to the external program. If true then the argument will be passed; otherwise, skipped. The default is true. | False
line | string | List of command-line arguments; will be passed to the executable as is. | False
path | <path> | The value for a PATH-like command-line argument; you can use `:` or `;` as path separators and NAnt will convert it to the platform's local conventions, while resolving references to environment variables. | False
unless | bool | Indicates if the argument should not be passed to the external program. If false then the argument will be passed; otherwise, skipped. The default is false. | False
value | string | A single command-line argument; can contain space characters. | False

### Nested Elements:

#### <path>

Sets a single command-line argument and treats it like a PATH - ensures the right separator for the local platform is used.

#### </path>

### Examples

- A single command-line argument containing a space character.

      <arg value="-l -a" />

- Two separate command-line arguments.

      <arg line="-l -a" />

- A single command-line argument with the value `\dir;\dir2;\dir3` on DOS-based systems and `/dir:/dir2:/dir3` on Unix-like systems.

      <arg path="/dir;/dir2:\dir3" />

#### </arg>

### Examples

- Adds all public classes contained in `myTest.dll` to a COM+ application and produces the `myTest.tlb` type library. If the application already exists, it is overwritten.

                  <regsvcs action="FindOrCreate" assembly="myTest.dll" />

- Adds all public classes contained in `myTest.dll` to `myTargetApp` and produces the `myTest.tlb` type library. If the application already exists, it is overwritten.

                  <regsvcs action="FindOrCreate" assembly="myTest.dll" application="myTargetApp" />

- Adds all public classes contained in `myTest.dll` to a COM+ application and produces the `myTest.tlb` type library. A new application is always created.

                  <regsvcs action="Create" assembly="myTest.dll" />

- Uninstalls the COM+ application contained in `myTest.dll`.

                  <regsvcs action="Uninstall" assembly="myTest.dll" />

### Requirements

Assembly: NAnt.DotNetTasks (0.91.3881.0)
