Hi I converted my app that was implemented in VS 2003 to .net 2.0 VS 2008 afterward my app became slow about 4 times than previous version!

is it normal or not ? Best regards

A: 

No. I have never heard of such a performance degradation before from upgrading the target framework.

.NET 2.0 uses another version of the CLR than 1.1, so there might be small differences. Perhaps you are running into some edge case, but we really can't tell without any more information.
