Question

当我开始构建应用程序时，Msbuild会抛出异常。如果有任何人对此错误有任何疑问，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某些MSBuild版本中，并且可能只发生在一些特定的项目文件中。

我见过在VS2010中出现类似错误的情况，并在后续版本中得到修复。我见过VS2013没有出现的情况，并且是VS2015或VS2017引入的（未检查所有版本）。这些案件可能并不相关。

要问一个关于内部工具问题的正确问题，您需要花一些时间修改（简化）项目的时间，直到你知道什么样的项目文件更改（或源文件更改）打开和关闭此问题，以及使用哪个工具版本。

Msbuild失败，并显示错误消息“字典中没有给定的密钥。”
