I'm using Visual Studio 2010 Ultimate. I have a C# WCF service application I want to target for Windows 2008 R2 Server Core. In the assembly framework dropdown, I see .NET 3.5, .NET 4.0 and the respective client profiles, but no profile listed for .NET 3.5 Server Core. Likewise, on the setup project launch conditions, there is no .NET 3.5 Server Core profile. I have installed the Windows 7 and 2008 .NET 3.5sp1 SDK but no luck. Any tips on how to target Server Core in my project? Thanks a lot.
