This issue is driving me insane: I was working on a recently created project and suddenly I was unable to debug that specific project.
I\'m using a local IIS 7.5 with t
I just discovered that the if the project URL you are using (right click your project, go to Properties, click on the Web tab on the left) happens to trigger your rewrite rule, then debugging using the play button won't work. The "fix" is to simply set your project URL to one that won't be rewritten.
For example, I am using URL rewrite to make sure that HTTP requests get redirected to HTTPS. As long as my project URL begins with https:// then I have no issues debugging (apart from the fact that I have to install an SSL cert on my development machine, but that's easy to work around).
