Crashing Quick Actions and Refactoring of Visual Studio 16.6

[carlospence]

I just updated to Visual Studio 16.6 and the Quick Actions stopped working, anytime I click on the Quick Actions the error below is displayed. I have update the MappingGenerator to the latest version and still having the same issue. Whenever I disable the plugin, every works as expected.

Hi,

Did you try to restart VS/OS ? Please also try to clear MEF cache with this extension https://marketplace.visualstudio.com/items?itemName=MadsKristensen.ClearMEFComponentCache

UPDATE: Cleaning Temp directory (%USERPROFILE%\AppData\Local\Temp\) could also help here.

Please let me know if that solved the issue.

Hi,

I have the same problem.

Things I've tried:

• cleared MEF Component cache
• reinstalled the extension
• cleared the temp folder (as suggested)

Nevertheless, I get to following exception: Microsoft.VisualStudio.ExtensibilityHosting.InvalidMEFCacheException: The Visual Studio component cache is out of date (assembly: MappingGenerator, Version=1.14.356.0, Culture=neutral, PublicKeyToken=null). Please restart Visual Studio.

Funny is that the exception states that I have the version 1.14.356.0 installed. But I definitely have the version 1.16.405 installed (downloaded from the GitHub releases page).

I'm running VisualStudio 16.6.2

Thanks. I've just reported this issue to Microsoft. I will provide a link to the ticket when I get confirmation.

@carlospence @mrdavidkovacs is it still an issue with the latest MappingGenerator and VS 16.7.2?

[mrdavidkovacs]

@cezarypiatek It worked for me yesterday using the latest version of the extension and Visual Studio 16.7.2. Thank you very much.
