Visual Studio Extension for Getting Pending Files for TFS

Question

Capture.JPGHi All,

I am trying to create an extension (vSix) for VS2022. The idea is to get all the pending file details and forward them to some other tools. I am unable to resolve the problem. If anyone has a suggestion, then please let me know.

I had created the extension for VS2019 and its working. But for VS2022 its not working.

Thanks in Advance.

Hello @One07k-4914 ,

Welcome to Microsoft Q&A forum.

Did you include the 2019 TFS assemblies but maybe didn’t change to use/install those for 2022?

Please try to re-add the TFS related assemblies, and test again.

See if this similar thread: CompositionContractMismatchException in VS 2015 Extension implementing ITeamExplorerSection helps.

Best Regards,

Tianyu
