I am using Visual Studio 2013 SP1.
After installing Roslyn I wanted to play with the samples. In the samples folder there is a project called MakeConstCS. So I hit F5, the experimental VS env is loaded. Then I create a new project and boom.
Normal Build Error incomplete Could not load file or assembly 'Microsoft.VisualStudio.LanguageServices.CSharp, Version=0.6.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
I get the same error when I try File->New->Project->Templates->C#->Roslyn->CodeRefactoring->F5
Any idea why this happens?
You need to install Roslyn into your VS experimental hive. This is listed in the Readme, and the SDK includes an exe to do so.
Correct way to reinstall Roslyn:
For debugging with VisualStudio2013
<VisualStudioVersion Condition="'$(VisualStudioVersion)' == '">12.0</VisualStudioVersion>
