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

Question

当运行在TeamCity的一个MSpec打造一步我得到在球队的城市记录以下错误：

我所做的建议的修改的machine.config和MSpec配置文件，但它似乎没有不帮帮我。

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

MSpec runner在Visual Studio本地正确运行的构建代理上本地引用编译的DLL。任何人都可以解释这个错误意味着什么，以及我可以如何解决它？

Answer 1

你可以检查mspec.exe或“编译的DLL”的属性，看看是否有security Unblock button。我有同样的错误和解除阻止修复它。启用loadFromRemoteSources没有帮助。
