I was browsing some of the awaited-for Visual Studio 2010 and I found a video about two interesting features related to what we do everyday (and I do not mean coding ;))

The first feature is related to debugging “history”. Normally, when you find a bug while running your program, you insert multiple breakpoints on the statements you suspect might caused it, and repeat the scenario or restart the debug session.

With history debugging, you don’t need to do so, since the history debugger “logs” every event in your application, so you can “pause” running and inspect all the previous events and may be check if there were “swallowed” exceptions.

The second feature, is when you want to modify some “unit-tested” code either for bug fixing or refactoring, and you want to re-run the impacted tests. Normally it is hard to determine which tests are affected so you run all of them, but with Test Impact Analysis in VS 2010, you can get the impacted tests once you save your modifications, so you can either commit your changes or undo.

Here is the 19 minutes video showing these two features on Channel 9
