.net-4.0

问题 I Opened my .net 2.0 ASMX webservice in VS2010 and migrated to .net4.0.

I tried running my existing asmx service using dataset as attachments in .net 4.0 and it worked

问题 ".NET Framework 4 Client Profile" is missing in the "New Project" window in Visual Studio 2010, so I cannot set it as a target framework. Any ideas? 回答1: That's normal.
