Where can I find good programming resources for SharePoint? -

I am trying to find a book or web context from which I am about to build, test, and deploy ASP Got good sense .NET pages, controls and web parts on a SharePoint web site. What I have found so far is either drag-and-drop stuff or administration material.

Is SharePoint really flexible with ASP.NET when it comes to expanding? A series of videos or tutorials will be ideal.

Thank you in advance!

This is just ASP.NET and is expandable to a certain extent. It all depends on what you just want to do.

I got wrox books very useful: Professional SharePoint 2007 development expert WSS 3.0 and MOSS 2007 programming

Have you checked so far?
