【问题描述】：
我将 Xunit.net 与 Visual Studio Online 托管构建一起使用。我的测试在本地和构建服务器上都被发现并运行良好。但是在构建服务器上，我得到了这个异常（导致构建达到“部分成功”状态）。这很奇怪，因为我的所有测试实际上都在被发现并运行。

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value HKLM\Software\Microsoft\Fusion!EnableLog to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

我在测试项目中安装了以下 nuget 包：
- xunit 1.9.2
- xunit.runner.visualstudio 0.99.2
其他单元测试框架，例如 MS Test 和 NUnit，都可以正常工作。这让我觉得问题出在 Xunit.net 而不是 Visual Studio Online。
我还在 xUnit.net GitHub 上打开了一个问题，但仍未解决。 https://github.com/xunit/xunit/issues/47
我怎样才能让它工作？有谁知道解决方法？我可以以某种方式隐藏错误消息吗？
