Can't add reference in visual studio 2019

Question

I have recently upgraded to Visual Studio 2019, and I get a weird problem.

When I am trying to add a reference to the project, I get an error message that says "sequence contains no elements".

Do you know how to fix it? I have tried to reinstall, but for no avail…

Answer 1

1. Click 'Project' menu
2. Click 'Add Reference' sub menu
3. Click 'Browse...' button
4. In the file name texbox, paste : 'C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0' (or any other framework version)

Voila! - add the file you wish
