为什么在 TeamCity 上运行 MSpec 时会收到 NotSupportedException？

Question

在 TeamCity 中运行 MSpec 构建步骤时，我在团队城市日志中收到以下错误：

我已对 machine.config 和 MSpec 配置文件进行了建议的修改，但似乎没有帮助。

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

MSpec 运行程序正在本地在 Visual Studio 中正确运行的构建代理上引用已编译的 DLL。谁能解释这个错误的含义以及我如何解决它？

Answer 1

您能否检查mspec.exe 或“已编译的DLL”的属性以查看是否有security Unblock button。我有同样的错误，Unblock 修复了它。启用 loadFromRemoteSources 没有帮助。
