I recently started a new job, and in my current environment I have a C# developer, who comes from a Windows Forms Development background, an SQL Server 2000/2005 DBA, a VB.NET/AJAX/JavaScript developer and another VB.NET developer. There is another guy that does C# as well. I must honestly say that working with all of them has proven that every single developer has his/her preferred approach to development. For instance the SQL Server 2000/2005 DBA and the VB.NET/AJAX/JavaScript developer work closely together and they seem to build all their application logic into SQL Server. The stored procedures that they build handle the majority of the application logic. And there is nothing wrong with this approach, but in my mind Microsoft have gone to great lengths to make things like data structures readily available in C# and VB.NET. Why do I say that? Because I prefer doing my application logic in the C# application. Are there any real performance benefits?
