title: Why does Visual Studio refuse to debug my ASP.NET application and attempts to attach to my browser instead
body: <p>I recently reinstalled visual studio 2015, and for some reason I can't start the debugger for an asp.net web application by pressing F5 as I used to do. Visual studio is trying to attach to my firefox.exe process ; at first it was complaining that the process was 64bits, and now I solved that it wants me to set a "start page" which I don't want to, and it doesn't start the web server in debug mode anyway. Which means I can't set breakpoints or catch exceptions in the debugger.</p>
