I've been promoting this at the booth at Tech Ed but also wanted to make sure I mention it on my blog.

We're having a VSX Developer Conference at Microsoft on September 15th and 16th.  It'll be a two day conference to go deep into developing extensions for Visual Studio, the VS shell, and DSL Tools.  The conference is open to the public and is pretty cheap - $100.  Compared to the price of Tech Ed, it's dirt cheap :)

Sign up soon though as space is limited.

Hope to see you there.
