如何修复“无法找到文件'C： CoolApp.vshost.exe.config'异常？

Posted 2021-03-30

我有一个程序，它使用浏览器Winforms控件导航到不同的网站，但是在5-10秒之后，它会在Visual Studio中抛出上述异常并突出显示以下行：

Application.Run (new MainForm ());

在Program.cs。

此外，我可以看到异常位置，因为我打开了CLR例外选项。

但为什么会这样呢。我没有对vshost做任何事情。我怎样才能解决这个问题？

编辑：调用堆栈：

答案

你可以在这里找到有关VSHost的详细信息：http://blogs.msdn.com/b/dtemp/archive/2004/08/17/215764.aspx

我也在SO中找到了类似的问题：mysterious exception "Could not find file 'D:xxxxinDebugxxx.vshost.exe.config'."

另一答案

在我看来，您正在尝试在没有安装调试器的机器上运行以调试模式编译的程序。
