Well, no.
Because your question is too underdefined and there is nothing like "web matrix's cshtml". That one is the extension associated with
Razor view engine[
^] in
ASP.NET MVC3[
^] and above. And you will get nothing with just a
login form.
ASP.NET authentication[
^] is more complex than that.
But if you start an MVC3 project in Visual Studio (not the empty project template), and you choose the internet site (form authentication), you will get a good sample. (
