db4o Developer Community

Dustin Campbell, a self-professed ''IDE guy'', is speaking at the .NET Developer's Association of Redmond this evening, on the future of Visual Basic in Visual Studio 2010, and I feel compelled, based on my earlier ''dissing'' of VB in my thoughts of PDC post, to give VB a little love here.

Hi, Recently we decided to evaluate how much impact (in performance) reflection represented in db4o.

Hi. That computer technology evolves day by day and the amount of information in this area is gigantic many of you already know (so do I), but today I was talking to a friend of mine and I realized how many books I want to ready (only in the subject Windows + .Net). If you are curious you can see the list here but most of them were not published ...

Hi, Just to let you know I've posted about Transparent Activation / Persistence to db4o blogs ;) Adriano

C# 4.0: Meet the Design Team Have fun Adriano
