List of DLLs No longer within the .NET Framework 4.0

Can anyone out there give me a list of the DLLS that are not in .NET Framework 4.0 but still are in  previous versions (2.0, 3.0, 3.5) ?
I need to test what happens when I run  under CLR 4.0 and not find the dll that still exist in previous .NET Framework Versions (2.0, 3.0, 3.5).

Do I need to modify my app.config to go looking for it in ( Binding redirect or something like that)?

I can find .NET Framework dlls that have obsoleted their content ( types/members) but not the whole DLL.

I found that same website before but it is stating the Assemblies' Types/Members; I looking for assemblies that have been completely removed in the next version of 4.0.

I think it all depends on your application configuration. If required .dlls not find for your application, it will not compile from VS IDE.

And if you are having software build earlier, it will throw exception at runtime that it doesn't find the mathing .dll file.

However I would like to know what you are trying to achieve exactly in last?
