Question

我从Azure Cosmos DB下载了入门示例应用程序，并且在Visual Studio Mac中出现以下错误

System.TypeLoadException: Could not resolve type with token 010000f6 (from typeref, class/assembly System.Diagnostics.Eventing.EventProviderTraceListener, System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089)
  at Microsoft.Azure.Documents.Client.DocumentClient.Initialize (System.Uri serviceEndpoint, Microsoft.Azure.Documents.Client.ConnectionPolicy connectionPolicy, System.Nullable`1[T] desiredConsistencyLevel) [0x00014] in <f7f11c3ada88490092c73d6bef54be97>:0
  at Microsoft.Azure.Documents.Client.DocumentClient..ctor (System.Uri serviceEndpoint, System.String authKeyOrResourceToken, Microsoft.Azure.Documents.Client.ConnectionPolicy connectionPolicy, System.Nullable`1[T] desiredConsistencyLevel) [0x00069] in <f7f11c3ada88490092c73d6bef54be97>:0
  at GraphGetStarted.Program.Main (System.String[] args) [0x00021] in /DocumentDB-Quickstart-DotNet-Graph/GraphGetStarted/Program.cs:29

它失败的代码

   DocumentClient client = new DocumentClient(url, authKey, policy);

这是packages.config：我是否需要为Visual Studio Mac设置不同的targetFramework？

<?xml version="1.0" encoding="utf-8"?>
<packages>

Answer 1

我认为Protocol.Tcp不是.NET Core。你能尝试用

吗？

new ConnectionPolicy {ConnectionMode = ConnectionMode.Gateway，ConnectionProtocol = Protocol.Https}））

或

new ConnectionPolicy {ConnectionMode = ConnectionMode.Direct，ConnectionProtocol = Protocol.Https}））

谢谢！

根据您的评论，您使用.net项目。请不要尝试在MacOS上运行.net项目。我们可以创建在Windows，Linux和macOS上运行的.NET Core个应用程序。我们还可以从官方tutorials获取有关azure DocumentDB和.NET Core的信息。

在Visual Studio Mac上使用DocumentClient的TypeLoadException
