This extension provides a quick way to attach to a web process for debugging. It supports attaching to WebDev, IISExpress, IIS, DNX and DotNet processes.

After installing, it'll add 2 items in the Tools menu (assign them shortcuts for quick access).

"Attach To Web Server" brings up a form that lets you select the process to debug.
"Reattach To Web Server" will auto-reattach to the previous process or show the process-select form if the previous process is no longer available.

Currently, it only supports auto-attaching to DNX and DotNet processes. I may update it later to support auto-attaching to other processes as well.
