.NET framework compatibility: 3.5 SP1 & 4.0 Client Profile

Question

My addin requires .NET 3.5 SP1, client has .NET 4 client profile, Is it enough? I am trying to find a picture or diagram which shows relations among versions of .NET framework. thanks

The other way to say, is .NET 4 client profile a superset of .NET framework 35 SP1(not .NET framework 35 client profile)? thanks

Answer 1

If your addin requires .NET 3.5 SP1 Client Profile, .NET 4.0 Client Profile is enough (it literally superseeds 3.5 SP1 in a sense). Read Version Compatibility in the .NET Framework for more info. Also see List of .NET Framework versions to see which comes after which.

Answer 2

Any .Net 3.5 application can run on Version 4.0. Be aware of the client profile missing many libraries, so if your addin requires the full .Net 3.5 runtime, it probably won't work on the client profile alone.
