When select add reference on any project new or old I get the following error in the visual studio 2017/2019
VS 2017/2019 Add a reference causes error: Error HRESULT E_FAIL has been returned from a call to a COM component
Solution:
#1 Open “Developer Command Prompt for VS 2017/2019” as Admin
#2 CD into “C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\PublicAssemblies” or CD into “C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\PublicAssemblies”
#3 Run “gacutil -i Microsoft.VisualStudio.Shell.Interop.11.0.dll“
#4 restart visual studio as administrator mode, VS 2017/2019 works for this flow.
Can you please let us know any other way to resolve this kind of issue and why this kind of issue happens suddenly?
