Suppose you have to fix a bug in an ASP.NET application. You’re a TDD-guy so once you identify it, you write a test which should reproduce it. Then you run it and… null pointer exception. Your testing framework may have pointed you to the exact line...

Today I was profiling an application. The timings pointed to a piece of code that executed a query using LINQ. I opened an SQL profiler and saw what queries were performed. Here they are: SELECT [t3].[value] AS [Key] FROM ( SELECT ( SELECT [t2].[Role

This past week at Camp Roberts has been incredible. All of the groups present did an amazing work, and we got to test InSTEDD’s GeoChat in a completely different scenario and integrate it with most of the other applications present to come up with...
