I created templates for Visual Studio in version Ultimate , but for some reasons I needed to migrate to Visual Studio Professional , and since then my VSIX projects do not work anymore.
Extensions to download in visualstudiogallery.msdn.microsoft.com when installed in VS Premium say "can not be installed in this version of the application".
So, is there any way to manipulate VSIX projects in Visual Studio Professional, without being on hand and not using VS Ultimate?
