Yesterday, I went to the QLD　MSDN User Group Meeting. One of presenters shows his opensource project, Glimpse. That is very very cool! This project is a Server Side version of FireBug in .Net. It will add a collapsible div at the bottom of page. In the div, all about the current request, including the server variable and session id, even MVC route. That is so cool! In addition, inside your code, you can add the track and the div will show them as well. Lastly, there is a remote tab inside this div. In the remote tab, you get the request information about the other clients which are on the same application. That is very helpful to mobile development. You can go into a page in the desktop and access the request information which is from the other mobile clients, rather than directly accessing them from a mobile device. I highly recommend to spend some time on learning this project!
