How to associate a XUnit Fact to a Test Case in TFS

Question

I am trying to figure out how to associate a Test Case in TFS 2018 to a Xunit Fact in a .Net Core project.
If i click on the XUnit Fact in the Visual Studio 2017 Test Explorer, the association option is disabled.

Does anyone know how to associate a Xunit Fact to a Test Case in TFS?

There is a Rest API could update work item filed.

For example:

PATCH https://servername:8080/tfs/DefaultCollection/_apis/wit/workitems/[testcaseid]?api-version=1.0

Content-Type: application/json-patch+json

Body:

[
  {
    "op": "add",
    "path": "/fields/Microsoft.VSTS.TCM.AutomatedTestName",
    "value": "[namespace.classname.methodname (e.g. UnitTestProject1.UnitTest1.TestMethod2)]"
  },
  {
    "op": "add",
    "path": "/fields/Microsoft.VSTS.TCM.AutomatedTestStorage",
    "value": "[assembly name(e.g. unittestproject1.dll)"
  },
  {
    "op": "add",
    "path": "/fields/Microsoft.VSTS.TCM.AutomatedTestId",
    "value": "[guid id]"
  },
  {
    "op": "add",
    "path": "/fields/Microsoft.VSTS.TCM.AutomatedTestType",
    "value": "Unit Test"
  },
   {
    "op": "add",
    "path": "/fields/Microsoft.VSTS.TCM.AutomationStatus",
    "value": "Automated"
  }
]

The AutomatedTestId is a Guid value, so you can generate a new Guid by using this C# code:

Guid g = Guid.NewGuid();
string s = g.ToString();
