If you’re using Firebird from .NET you should visit my talk on Firebird Conference 2011. This year it’s in Luxembourg at November 25-26.
There’s no schedule yet (in time of writing), but I can tell you, that my talk will be on Friday, for sure. Topics covered are obvious. Everything worth mentioning from last year or so in .NET provider development and also some future plans. Feel free to come and ask whatever .NET provider related (or Firebird) you want.
P.S. Would you be interested in picking up some Twitter questions during the talk?
