One of my favorite sites to learn more about the .net framework is found at wiki.asp.net. I spend a good amount of time reading through the numerous articles presented on the site.  The ASP.NET Developer wiki allows me to learn something new quickly and from the view of my peers. Here’s a list of recommended articles that I’ve found beneficial: of some of the articles I’ve found most beneficial:

• ASP.NET Open Source Projects: This article provides a number of links to open source projects developed in .net.  I’m a firm believer that you can learn a great deal by looking at others’ code, it’s probably my favorite learning mechanism and way to spark new ideas.
• Design Patterns: If you don’t know about design patterns, I’d recommend doing some research about them as they can save you a great deal of time.  You’ll be amazed to see how many of the design patterns described in this article are either present in the code you write or within the framework you use.
• Architecture: These links will teach you about everything from software architecture to the asp.net framework architecture. A lot of these articles are interesting reads that I guarantee will help solidify your knowledge base.

Hope you enjoy some good reads!
