How to access User.Identity.GetUserId() in Class library

Question

I am going to use a class library as a data layer in my mvc.net web application. Is it possible to access User.Identity.GetUserId() from within the class library.

I can access username by using HttpContext.Current.User.Name but not UserId.

Meanwhile, Microsoft.Aspnet.Identity reference is not accessible in class library project.

thanks

Just added Microsoft.AspNet.Identity.Core.dll to my console application references. Unfortunately this reference does not exist in list of References nor in Extensions. I borrowed it from my web application's bin folder. I'm wondering why Microsoft has not added this in the list of references!
