[Mono-dev] [PATCH] Implement support for compiled regular expressions in profile 1.x

The runtime has support for generic types in profile 1.0 as well, 
OnDeserializedAttribute could also be used, just like new case 
insensitive and culture invariant string operations/comparison, static 
classes could be supported by profile 1.0 C# compiler because no runtime 
support is needed, and this is just some examples of possible 2.0 suff 
for internal use in 1.0 class library.

As far as I know none of them or any other 2.0 features are used outside 
of mscorlib.dll.

Also note that this is a complete patch including replacing the generic 
Dictionaries with non-generic Hashtables.

Attached a more recent version of the patch with some minor updates.
