How do I add custom header using C# generated proxy client?

[ThisNoName]

I have WebApi project, tested the custom header using Postman, works fine. But can't figure out how to add the header using WebApiProxy generated C# client.

 var client = new TestClient();
 client.HttpClient.DefaultRequestHeaders.Add("Clientid", "tester");
 var test = new TestClient().Get("123");

Not sure if I understand it correctly. Appreciate your help. Thanks.

Nevermind, this seems working fine. Not sure what I missed earlier.
