Add Fakes Assembly does nothing and does not create Fakes folder

Question

Hello, I am trying to use Microsoft Fakes and am following instructions on this page: Use shims to isolate your app for unit testing

I opened the Solution Explorer and expanded the references section of my unit testing project. I then right clicked on a referenced project (part of the same solution) I want to fake and clicked on "Add Fakes Assembly".

The Visual Studio status bar changes to show "Processing fakes configuration" for a minute, and then goes back to ready.

However, I can't see any Fakes folder, git status returns empty. Also VS does not recognize ShimsContext as valid.

I am using VS 2022 Enterprise:

Is there any thing which I could be missing?

Hi @fauzan, 

Welcome to Microsoft Q&A! 

Does it occur in other reference assemblies? 

Please ensure the referenced project is correctly loaded and builds successfully. 

You can update your VS2022 to the latest version and manually delete the .vs, bin and obj folders.

Then, rebuild the solution and check it again. 

You can also create a new test project and re-add the project reference, then, check if the “Add Fakes Assembly” works. 

Sincerely,

Anna
