推荐答案
我尝试了上述解决方案(删除所有已安装的 Nuget 包、.vm 文件夹等)，但对我不起作用.我使用的是 Visual Studio 2019 v 16.8.4.更新到版本 16.8.5 为我解决了这个问题.
I tried the solution above (deleting all the installed Nuget packages, .vm folder, etc) but it didn't work for me. I was on Visual Studio 2019 v 16.8.4. Updating to Version 16.8.5 solved this issue for me.
