NCrunch 3.28 fails to initialize after VS 2019 update to 16.3.10

NCrunch was working fine for me before I updated VS 2019, but now it just shows the "You can enable NCrunch by selecting 'Enable' ..." message, and Enable is greyed out.

I have tried:
* deleting all obj, bin folders
* removing ncrunch temp, cache, project files
* resetting VS settings
* uninstalling and reinstalling ncrunch

Would it be possible to get a patch for this, as we're currently tied to a license with a max version of V3.28.

Thanks!

Hi, thanks for sharing this problem.

This issue is caused by a breaking change introduced by Microsoft in an update to VS2019. We resolved it in NCrunch v3.31, with builds that were made available as soon as we became aware of the problem.

Please note that we do not release patches for old versions of the software as to do this would involve warranting future compatibility with all versions of Visual Studio (something we can't do), and it would completely break the licensing and release model.

You have the option of either upgrading your license or downgrading your version of VS2019 to a build released prior to the breaking change.

Thanks for your dizzyingly quick response!
Totally understand. Hopefully can get something sorted soon.
