Running Visual Studio 2013, I'm trying to debug a Visual Studio project template, as well as a visual studio extension. I've followed the instructions given here, but when the new instance of Visual Studio launches, I get:
Microsoft.VisualStudio.ExtensionManager.NotInstalledException was unhandled Message: An unhandled exception of type 'Microsoft.VisualStudio.ExtensionManager.NotInstalledException' occurred in mscorlib.dll
I've tried disabling all Visual Studio Extensions (that can be) - that didn't help.
