I\'m using VSIX Manifest Designer under VS2013. I\'ve added Microsoft.VisualStudio.Pro product identifier and [10.0,13.0) version
It is working pretty good (Thanks a lot to Igal), if the VSIX is developed in VS 2012, and installed in VS 2015. However, the reverse is not working (means developed in VS 2015 and try to install in VS 2012) After analyzed Activitylog .xml, i found a work around
Could not load file or assembly 'Microsoft.VisualStudio.Shell.14.0, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.
Workaround I did Remove VisualStudio.Shell.14.0 and Install VisualStudio.Shell.11.0 using Package manager console (Install-Package VSSDK.Shell.11), and installed in VS 2012. Now Working as expected
