Adding Authorization Headers to WinRT's HttpClient

WinRT's HttpClient lacks the .NET Credential class for setting authorization headers. This article details a workaround for adding authorization headers, specifically using OAuth tokens.

The Challenge: How to add an authorization header (e.g., for OAuth) to a WinRT HttpClient request?

The Solution: Utilize the AuthenticationHeaderValue class:

httpClient.DefaultRequestHeaders.Authorization = 
    new AuthenticationHeaderValue("Bearer", "Your OAuth token");

This code snippet constructs an authentication header using the "Bearer" scheme and your OAuth token. Adding this to DefaultRequestHeaders.Authorization ensures the header is automatically included in all subsequent requests made by this HttpClient instance.
