为什么在TeamCity上运行MSpec时会出现NotSupportedException？

Question

在TeamCity中运行MSpec构建步骤时，我在TeamCity日志中发现以下错误：

我已经对机器做了建议的修改。config和MSpec config文件，但它似乎没有帮助。

<runtime>         
  <loadFromRemoteSources enabled="true"/>
</runtime>

MSpec运行程序正在本地引用构建代理上的编译DLL，该构建代理在Visual Studio中本地正确运行。有人能解释这个错误的含义以及我如何解决它吗？

Answer 1

你能检查mspec.exe或"编译DLL"的属性，看看是否有安全的Unblock按钮。我有同样的错误，Unblock修复了它。启用loadFrom远程资源没有帮助。
