To resolve it, follow following steps: First of all, close all the instances of Visual Studio. Open the Developer Command Prompt for VS 2019 with admin privileges, as shown in the following screenshot: Now, navigate to the "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\ Common7\IDE\ PublicAssemblies" Enter the following command in the console window: `CD "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\PublicAssemblies"` Now enter the following command: `gacutil -i Microsoft.VisualStudio.Shell.11.0.dll` Once you get the Assembly successfully added to the cache message in the console window (as shown in the following screenshot), start the Visual Studio 2019 instance. Now open your project and try to add the assembly reference. It will work this time. Posted On: 09-May-2020 21:55 Thanks. It works for me. - sid 10-May-2020 03:10 thanks alot (issue solved) :) - mina kamel 02-Sep-2021 04:17
