TypeLoadException with DocumentClient on Visual Studio Mac

问题

I downloaded the getting started sample app from Azure Cosmos DB and am getting the following error with Visual Studio Mac

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

And the code where it fails

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

Here's the packages.config: do I need to set a different targetFramework for Visual Studio Mac?

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

回答1:

I think Protocol.Tcp is not is .NET Core. Can you try using

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

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

Thanks!

According to your comment, you use .net project. Please don't try to run .net project on the MacOS. We can create .NET Core apps that run on Windows, Linux and macOS. We also could get info about azure DocumentDB and .NET Core from the official tutorials.
