TechEd trade show
At the CCIB (Centre Convencions International Barcelona) where TechEd is held, there's also a trade show where a lot of the interesting 3rd party .NET development companies are showcasing their products. It's a great opportunity to get a look of the new cutting edge technologies that are being marketed either using or for the .NET framework.

I recently held a demonstration at several of the Danish universities, showcasing - amongst other - the PreEmptive DotFuscator product. As PreEmptive had a stand at the trade show, I got a great opportunity to meet up with them and get nice talk about DotFuscator and their view upon Obufscation. Also I got to meet Catherine Revil who helped me out with my last moment emergency problem before my last demonstration.
On my way out I got caught up by Nolics who were also demonstrating their "reverse" O/R mapper for Visual Studio 2005. Usually when we talk about O/R mappers we think of tools like NHibernate - a way to transform our existing database into .NET classes with which we can manipulate our data type safely. The Nolics O/R mapper goes the other way around. They've invented a DSL (Doman Specific Language) in which we write our database objects which in turn creates our .NET objects and creates the corresponding objects in our backend database, whether that be Oracle, SQL Server or any other database that is supported.
