我在控制台应用程序中自行托管 SignalR。如果计算机上安装了 Visual Studio，则代码可以正常工作。但是，当我构建并发送到没有 Visual Studio 的机器时，代码在尝试启动 signalR 时失败，并给出以下错误。
Could not load file or assembly 'Microsoft.AspNet.SignalR.Core, Version=2.2.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
使用Visual Studio 2017编译代码。

最佳答案
事实证明，我只需要在配置文件中添加一行，一切正常。要解决此问题，请添加条目“loadFromRemoteSources”，如下所示。
<configuration>
<runtime>
<loadFromRemoteSources enabled="true"/>
</runtime>
</configuration>
