Last week I went to a VISUG and MSDN event in Brussels where Scott Guthrie held 3 talks about VS2010, Silverlight 4, asp.Net and MVC. The event was very interesting, but I’m not going to dwell on the contents.

Everyone got a red tshirt to wear, as can be seen on the underneath photo. Somewhere near the end of the second session, I got to warm wearing the tshirt, and put it in my bag. I had no idea that my blue Google Maps tshirt would be so visible though. Setting in the middle of the room, this wasn’t really subtle if I look at it now, esp since it says “I am here”

This is the model of tshirt I was wearing:

While working on .Net download library, I realized I still didn’t know how to fire events from the background threads onto the main thread (meaning the thread that started the download by calling Start). I posted query on how to do this in vb.net on several forums, and got some helpful responses at MSDN. Apparently, the thing I’ve been searching for is called the Event-based Asynchronous Pattern, which is a general pattern for asynchronous operation’s with events. I have done some familiarization with it by doing the entire walk-through, and I also started implementing it into the Download class. I’ll probably commit my current code this weekend, hopefully with working cross thread events
