Obtaining Runtime call stack using visual studio extension

Hi Team,

Is there a way to obtain runtime call stack for a given .net application using extensions. I know this is possible because I could see this being implemented in the link below: http://visualstudiogallery.msdn.microsoft.com/1d1a129c-b22f-49da-93e4-eb0cdc34e98c

But its not the open source project to get the code base. I would want to achieve the same thing to one of my project, but a bit differently based on the project needs.

Is there any way for me to achieve the same using .net extensions. Any help would be greatly appreciated!!

Thanks & Regards,
