Where is the CorrelationID in MVC 6

How do I get the correlationID of a request using MVC 6?

I want to use it when I log a message so that I can track a request through the system.

In previous versions I would have used the HttpRequestMessageExtensions.GetCorrelationId method: https://msdn.microsoft.com/en-us/library/system.net.http.httprequestmessageextensions.getcorrelationid%28v=vs.118%29.aspx

In the newest versions, HttpContext directly exposes a TraceIdentifier property you can use as a correlation identifier: https://github.com/aspnet/HttpAbstractions/blob/dev/src/Microsoft.AspNetCore.Http.Abstractions/HttpContext.cs#L72

public void MvcAction() {
    var identifier = HttpContext.TraceIdentifier;
}

In older versions, you might have to use the IHttpRequestIdentifierFeature feature to retrieve the request identifier:

public void MvcAction() {
    var feature = HttpContext.Features.Get<IHttpRequestIdentifierFeature>();
    var identifier = feature.TraceIdentifier;
}
