Update: As pointed out by in the comments below, this solution is not thread safe, so I guess the solutions discussed above is still the best way.

I get around with the problem by registering the HttpContext into my DI container (Application_BeginRequest) and resolve it whenever I need it.

Register:

this.UnityContainer.RegisterInstance(new HttpContextWrapper(HttpContext.Current));

Resolve:

var context = Dependencies.ResolveInstance();
