Customizing windows 7 login with Credential Providers

Question

Usually, Windows 7 uses username and password to authenticate the user.I need to customize this feature.I would like to write a windows service that will allow some external device or authentication provider to log a user into windows.For example, a finger print reader can log a user into windows via fingerprint instead of password.

So I am trying find a C# API for this purpose(like GINA.DLL ).

Can anyone point me in the right direction in terms of what I need and where I should start researching how to make such a thing?

I have gone through following link. 我已经通过以下链接。 http://msdn.microsoft.com/en-us/magazine/cc163489.aspx . It contains the information. But examples are in C++.
