I have good experince with troubleshooting - so questions I ask often refere to where I think the problem is.

I'm a fulltime deleveloper working with .Net C# working with Linq, WinForms (DevExpress) and Entity Framework.

My favorite tool is LinqPad - all my C# PoC are created there. Also i'm a big fan of ReSharper.

Also I have an MCPD in .Net 4, Windows Developer
