I'm speaking at TechEd Europe in Barcelona on DSL Tools. Go here and look me up under the list of speakers to see details of my session on DSL Tools. There's also a talk from the VSX (VS Ecosystem) team on the new VS Shell given by James (including a demo of hosting a DSL in that shell), and James and Steve are participating in a Q&A session on customising Visual Studio. The ecosystem team will also be running a booth on Visual Studio Extensibility.
I'm arriving Sunday night, and leaving Friday evening. Come to the booth if you want to talk. See you there.
