As a matter of fact I’ve been learning Java (for SCJP) and Microsoft .NET (because of project change) recently.
This week I attended two crash courses:
- Programming with C# (course 2124C)
- Core Web Application Technologies with Microsoft Visual Studio 2005 (workshop 2543)
Those courses were fine; I refreshed a lot and learned some new stuff as well. Now it’s time to play around with this knowledge in real world 
I’ve done a lot of searching on google for this type of content. Glad I finally found this site! Great work.
