我是遇到了 Github 扩展经常在 Visual Studio 启动时报错，找了一下可以尝试以下方法：

首先卸载插件

然后删除 %LocalAppData%\Microsoft\VisualStudio\15.0_{some ID}\privateregistry.bin 和 privateregistry.user.bin 两个文件

然后再安装插件

应该就好了…

另外报错时多阅读错误日志，从错误日志中寻找错误原因来解决。

Thanks to the Jetbrains guys I found the solution. Try this if you have the same problem:

By the way I had to proceed in a slighly different way:

- uninstall R# and JustMock (even the Telerik.JustMock.VS2017.vsix which is the VS extension saved in the Telerik folder)

- delete %LocalAppData%\Microsoft\VisualStudio\15.0_{some ID}\privateregistry.bin and privateregistry.user.bin file (please backup them first)

- reinstall R# and JustMock (also the Telerik.JustMock.VS2017.vsix which is the VS extension saved in the Telerik folder)

- start Visual Studio and both problems should be solved
