Msbuild失败，错误消息为“0”；字典中不存在给定的键。”；

Msbuild在我开始生成应用程序时引发异常。如果有人知道这个错误，请告诉我

谢谢。

这是一个内部错误。您可以通过异常类型以及错误代码（MSB0001）来判断。这意味着它只会发生在特定的MSBuild版本中，并且可能只发生在某些特定的项目文件中

我见过类似的错误出现在VS2010中，并在后续版本中修复。我见过一些案例，在VS2013中没有出现，在VS2015或VS2017中引入（没有检查所有版本）。这些案例可能没有关联

要问一个关于内部工具问题的适当问题，您需要花费一些时间

修改（简化）项目的时间，直到您知道什么样的项目文件更改（或源文件更改）会打开和关闭此问题，以及使用哪个工具版本。
