Thin ASP.NET-based portal platform

Question

I am looking for a (very) lightweigted portal framework that is based on ASP.NET. I know systems like DNN , Umbraco, or Sharepoint Foundation 2010 . But this framework seems to me too heavy and swollen. What are good and subtle alternatives (free commercial use)? The framework should provide at least navigation support, authentication, and a basic CMS . And it should be possible to integrate other aspx pages (applications) into websites or similar containers.

Answer 1

What about Kooboo? -> http://kooboo.codeplex.com/

or "Mojoportal" -> http://www.mojoportal.com/

Answer 2

I think that Umbraco actually seems rather light, I do not think that you should reject it because it is heavy.
