Is there any guide lines on upgrading from Version 3.7 SP3 3.5 framework to SP4 4.0 framework? Not having much luck here. Trying to run it from with Visual Studio. I get "This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. "
Not sure which directions to look. How do I get the VS2010 to use the 4.0 framework for this site when in debug mode?
Also getting this.
