After installing extension relative line numbers in Visual Studio 2017 success, I opened a new project and found that the relative line number plugin is not loaded correcly.
Open logs in ActivityLog.xml I saw following error

You can fix this issue by reference this with a little revision
- Launch “Developer Command Prompt for VS 2017” as Administrator
- Go to VS 2017 installation folder cd C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise
- gacutil -if Common7\IDE\PublicAssemblies\Microsoft.VisualStudio.Shell.Interop.dll
key point is last line, Microsoft.VisualStudio.Shell.Interop.[8|11|12].0.dll won't work for me.
Hope this helps, happy coding 🙂
