Handle netstandard1.6 with xUnit

Question

I am looking to use a test framework for a netstandard1.6 library. I tried to follow and edit Getting started with xUnit.net (.NET Core / ASP.NET Core) without success. Follow the xUnit's tutorial with a dotnetcore lib on VS 2015 Update 3 RTM with my project.json file to reproduce the error.

project.json :

{
  "version": "1.0.0-*",
  "testRunner": "xunit",
  "dependencies": {
    "NETStandard.Library": "1.6.0",
    "xunit": "2.2.0-beta2-build3300",
    "dotnet-test-xunit": "2.2.0-preview2-build1029"
  },
  "frameworks": {
    "netstandard1.6": {
      "imports": "dnxcore50"
    }
  },
  "runtimes": {
    "win10-arm": {},
    "win10-arm-aot": {},
    "win10-x86": {},
    "win10-x86-aot": {},
    "win10-x64": {},
    "win10-x64-aot": {}
  }
}

Error:

Severity    Code    Description
Error       NU1002  The dependency dotnet-test-xunit 2.2.0-preview2-build1029 does not support framework .NETStandard,Version=v1.0

Can I downgrade to a version of .netstandard supported by dotnet-test-xunit 2.2.0-preview2-build1029? Is there any known work around to use xUnit with it?

As I am a bit new project.json and dotnetcore, I might missed something useful.

This worked for me. It seems existing xunit versions do not support the netstandard 1.6 library yet. Try changing your project json to look like this as provided for in xunit site. This also assumes that you created a .net core library project

{
  "version": "1.0.0-*",
  "testRunner": "xunit",
  "dependencies": {
    "xunit": "2.2.0-beta2-build3300",
    "dotnet-test-xunit": "2.2.0-preview2-build1029"
  },
  "frameworks": {
    "netcoreapp1.0": {
       "dependencies": {
          "Microsoft.NETCore.App": {
             "type": "platform",
             "version": "1.0.0"
           }
         }
      }
   }
}
