Hi!

First thing to admit is that we don't have in-house applications with .NET Framework 3.0, but we expect it to work because UltiDev Cassini treats .NET Framework 3.0 the same way as IIS: it does not see it as a separate .NET Framework. As we see it, ".NET Framework 3.0" name is a marketing gimmick. We are not saying that functionality of 3.0 is not valuable - it is, but every real framework release has its own version of mscorlib, while .NET 3.0 has no mscorlib 3.0 and WCF is happily registered in the GAC of .NET 2.0. If you open WCF assemblies that supposed to be 3.0 in the Reflector, you will see that it references mscorlib 2.0. Therefore, if references are resolved in your app, we'd expect your WCF functionality to have no trouble working under UltiDev Cassini 2.0. If not, please let us know.

Best regards,
UltiDev Team.
