Visual Studio 2010 was released yesterday

Unfortunately, I have just checked the MSDNAA site and they still do not have the release version of Visual Studio 2010. They only have an old Beta2.

My Plans for this Blog

I intend to post new things I learn or run into or that come to mind on at least a weekly basis. Sometimes may be daily. I'm planning on starting after the course ends so I do disturb the peace of the final project. You have options to unsubscribe yourself from this Blog site completely and you are welcome to stay as you fell like it. It's all up to you. I also would be open and willing to respond to those tough questions you may run into assuming the volume of questions would be manageable...... Knowing you guys, I think it will be very quite in this neighborhood.
