I have a vsix project. I use commandtool and create files. I upgraded .net framework (4.6.1 to 4.7.2) and packages
I run project, everything is ok. But I get error when I click Extension's button.

I checked error in XML file. Error description is
Description: Could not load file or assembly Microsoft.VisualStudio.Threading, Version=16.8.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a; or one of its dependencies
But there is package in References
Do you have any idea?
Best Regards
