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:
- Uninstall all the Roslyn extensions
- Delete %LocalAppData%\Microsoft\VisualStudio\12.0Roslyn
- Using regedit delete HKCU\Software\Microsoft\visualStudio\12.0Roslyn and 12.0Roslyn_Config
- Run Install Roslyn Preview into Roslyn Experimental Hive.exe
- Run Roslyn End User Preview.vsix
- Run Roslyn SDK Project Templates.vsix
- Run Roslyn Syntax Visualizer.vsix
For debugging with VisualStudio2013
- Check the project file entry and use the correct version of your VS instance:
<VisualStudioVersion Condition="'$(VisualStudioVersion)' == '">12.0</VisualStudioVersion>
