• Debugging asp.net suddenly stops

  - by Lieven Cardoen

  I have a strange error. I'm debugging an asp.net site and suddenly it stops. Visual Studio stays in debug mode and my web application stays on running just fine. I found this post on, but I don't think a background thread is causing the problem. There's even a try catch around the code where it usually stops debugging, but the catch is not triggered... Everytime I try it, it stops at a different place in the code.

• Possible ways of representing data in memory (.net)

  - by This is it

  Hi What are the possible ways of representing data in memory in .Net (or in general)? It would be great if data could be sorted and looked up by key (or multiple keys). We are thinking to use collections, arrays, list of collections/arrays. One object would be in several collections (one sorted asc, other desc, etc.). Maybe this is not a good idea, and we would like to hear some other possible solutions. Thank you
