如何在ASP中实现TokenProvider。NET Identity 1.1夜间构建?

I'm trying to implement password reset functionality with nightly build of ASP.NET Identity 1.1. There is a UserManager.GetPasswordResetToken method, but it throws an exception "No ITokenProvider is registered". Is there an built in token provider in ASP.NET Identity? If yes, how I can register it? If no, how I can implement one? Will be default Token Provider in the 1.1. release? And final question, is there an estimated 1.1 release date?I'm trying to implement password reset function
