My project was created for .NET 4, and the version of System.Net.Http was a link to version 2. I just upgraded to .NET 4.5 because I wanted to make something from this routing material , and I needed a link to version 4 of the assembly System.Net.Http I made.
However, my web services return an HttpResponseMessage that does not exist in version 4. of the assembly.
How should I proceed?
