Turn on CPS for a C#/VB project

Note that SDK-style projects automatically open in CPS. C#, VB and F# projects use the Managed Language Project System.

You can tell a project is loaded by CPS because the "Refresh" button in Solution Explorer is removed.

To force a legacy project to be loaded by CPS do one of the following:

• Rename a .csproj or .vbproj to .msbuildproj and add to a new solution, or
• In your .sln file, replace the project type GUID {FAE04EC0-301F-11d3-BF4B-00C04F79EFBC} with {13B669BE-BB05-4DDF-9536-439F39A36129}
