HttpFactory and AddHttpClient in dependency injection

[yonail]

Hello!

I'm trying to figure out how I can benefit from the new .netcore HttpFactory dependency injection to register the VSS clients in my startup class like so:

services.AddHttpClient<WorkItemTrackingHttpClient>(client =>
{
    // custom configuration
});

and then in a service/controller method:

public async Task Method([FromServices] WorkItemTrackingHttpClient client, int id)
{
    var workitem = await client.GetWorkItemAsync(id);
    //do something with the workitem...
}

Currently, I'm facing this exception when doing the above:
InvalidOperationException: A suitable constructor for type 'Microsoft.TeamFoundation.WorkItemTracking.WebApi.WorkItemTrackingHttpClient' could not be located. Ensure the type is concrete and services are registered for all parameters of a public constructor.

Has any one managed to do it?
Would be good to have a sample for this.

Thanks,
Yoni
