Question

当我打开现有的C＃项目或创建一个新的C＃项目时，我的visual studio 2015 RC崩溃了。如果我创建或打开一个C ++项目，它不会崩溃。

这是堆栈：

我在VS 2015 Enterprise RC和RTM上遇到过这个问题。我注意到VS 2015 RTM显示了重复的项目模板（例如，C＃控制台应用程序列出了两次）。

我认为在安装VS 2015 RTM之前运行的VS 2015 RC的卸载例程在我的机器上留下了导致问题的一些东西。

这就是我在机器上修复问题的方法（测试系统，而不是我的日常生产开发者机器（！））：

创建系统还原点
卸载VS 2015 RC
手动删除文件夹：C：\ Program Files（x86）\ Microsoft Visual Studio 14.0
手动删除文件夹：C：\ Users \\ AppData \ Local \ Microsoft \ VisualStudio \ 14.0
手动删除文件夹：C：\ Users \\ AppData \ Roaming \ Microsoft \ VisualStudio \ 14.0
重新启动
重新安装VS 2015 RTM（显示一些问题）
修复VS 2015 RTM

现在一切似乎都按预期工作了。
