Authentication not working in MVC3

I am working on a Facebook canvas application. I created a sample project using the latest ASP.net MVC3 RC2, and use the exactly same settings as provided in the sample (MVC2). But it's not working. After a user clicks Allow to grant the permission, there are an unendin开发者_JS百科g redirects between the site and Facebook. Does anybody have experience on this problem? Any workaround for this issue?

I had the same issue in web forms application. But the error resolved after setting Site URL under Website tab (in facebook app registration settings) to Canvas URL (under facebook integration settings).

The error is solved by the Facebook C# SDK...
