C# 交互式 - 无法加载文件或程序集

Question

我正在尝试使用C# Interactive测试一些mongodb驱动程序，但是当我尝试创建MongoClient时，我会收到以下异常：

> var client = new MongoClient();
Could not load file or assembly 'System.Runtime.InteropServices.RuntimeInformation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
  + MongoDB.Driver.Core.Connections.ClientDocumentHelper.CreateOSDocument()
  + Lazy<T>.CreateValue()
  + Lazy<T>.get_Value()
  + MongoDB.Driver.Core.Connections.ClientDocumentHelper.CreateClientDocument(string)
  + MongoDB.Driver.Core.Connections.BinaryConnectionFactory..ctor(MongoDB.Driver.Core.Configuration.ConnectionSettings, MongoDB.Driver.Core.Connections.IStreamFactory, MongoDB.Driver.Core.Events.IEventSubscriber)
  + MongoDB.Driver.Core.Configuration.ClusterBuilder.BuildCluster()
  + MongoDB.Driver.ClusterRegistry.CreateCluster(MongoDB.Driver.ClusterKey)
  + MongoDB.Driver.ClusterRegistry.GetOrCreateCluster(MongoDB.Driver.ClusterKey)
  + MongoDB.Driver.MongoClient..ctor(MongoDB.Driver.MongoClientSettings)
  + MongoDB.Driver.MongoClient..ctor()

以下是详细的复现步骤：

通过命令行安装最新版本的MongoDB驱动程序。

C:\dev>nuget.exe install MongoDB.Driver -OutputDirectory tools -ExcludeVersion

打开 C# 交互窗口并导入 dll 文件。

Type "#help" for more information.

> #r "c:\dev\tools\System.Runtime.InteropServices.RuntimeInformation\lib\net45\System.Runtime.InteropServices.RuntimeInformation.dll"

然后尝试创建MongoClient。

我没有你的答案，但我曾经与类似的恶魔作战。融合日志记录是你的朋友：

最近我遇到了这个问题，从 web.config 中删除 System.Runtime.InteropServices.RuntimeInformation 代码解决了它：（如果你有 Windows 应用程序，请查看 app.config）。

移除这段代码就可以解决问题：

<dependentAssembly>
  <assemblyIdentity name="System.Runtime.InteropServices.RuntimeInformation" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-4.0.2.0" newVersion="4.0.2.0" />
</dependentAssembly>
