Question

我有一个干净的Visual Studio 2017和ReSharper安装，但决定将其升级到15.6.2 for Visual Studio和2017.3.3 for ReSharper。不幸的是现在我继续在Visual Studio上发生崩溃，弹出说：visual studio an exception has been encountered. this may be caused by an extension。

所以我禁用了ReSharper但它继续运行，错误日志如下：

有没有人在Visual Studio 2017中遇到过这种行为，你是如何解决的？

信息：错误仍然发生在15.6.3

中

Answer 1

不幸的是，我有点绝望 - 耐心 - 所以我对Visual Studio进行了全面修复，这似乎使它工作正常。然后我不得不重新安装ReSharper。

很抱歉，我们希望花更多时间找到合适的解决方案......
