With the state of diagnostics on the web being where it is, we are left needing to perform a job that is much harder than it should be. Too often, the tools we are provided with only show a part of the picture, leaving us to simply guess what might be happening behind the scenes. Glimpse is an open source project that aims to change the way we think about diagnostics and the frameworks we interact with. After releasing Glimpse at Mix 11, Glimpse has become a tool that is used daily by tens of thousands of developers around the world. Learn how to use Glimpse to reveal what is happening within your ASP.NET MVC and WebForms sites. See what tools are included out of the box and how you can easily extend it to suit your needs.
