How do I develop my first web part?

Question

I am a newbie in SharePoint development and I have an Oracle and ASP.NET background. Can you please guide me to any tutorial which can take me from building Web parts to showing them on a SharePoint site.

I am using VS 2008 and SQLServer 2008 with MOSS 2007.

Answer 3

I would also suggest having a look at the following books by Tedd Pattison which will help get you started:

Inside WSS 3.0

Inside MOSS 2007

Answer 4

Probably one of the most usefull tools in Sharepoint development (especially in WSS3.0 and MOSS2007) is WSPBuilder Be sure to install it on your machine as developing webparts and features is much easier with this plugin.
