How to design Simple Facebook Application ?

Question

Hello all,

I have been working on Facebook.NET SDK since last week.

After some searches on internet, i decided to develop an application as iframe within xfbml for my .net site

But I could not find any document for web site design ?!?

I wonder that how can i prepare a site as html (for client side) like apps.facebook.com/ilike/ ?

Could you help me regarding the issue above ?

Thanks

Tep
