While attempting to review and leverage the TypeRefHash, we came across a few issues we would like to bring up and hopefully resolve through discussion/implementation:

• Could you explicitly state the sort order in the definition of TypeRefHash? It seems the sort order is the default C# sort order, which may cause some problems as stated in subsequent bullets:
• Since the C# default sort order is leveraged, the generated TypeRefHash may change based upon locality/language. For example, if the default language setting for a user is French, the generated TypeRefHash may be different than if the default language setting is English.
• The C# default sort order treats some characters differently than, say, Python. Having a sorter which is language agnostic will better enable portability and implementation in other languages/environments.
• The sort order is case-insensitive, while the hash is case-sensitive. The TypeRefHash can be defeated by altering the case of some of the strings. In comparison, an ImportHash converts all names to lower-case before both comparing and hashing.
