ASP.NET MVC5/IIS Express unable to debug - Code Not Running


I start a VS2013 VB.Net MVC5 Web Application, set a breakpoint in HomeController About method and run "Start Debugging", navigate to About page and receive the message "Code not running - The current Thread is not currently running or the call stack could not be obtained" preventing any debugging.

If I set a breakpoint in Global.asax Application_Start, the breakpoint works fine. Changing the "Enable Edit & Continue" makes no difference.

Anyone have any ideas what is happening?

Update: My environment was Windows 8.0 Pro with VS2013 Ultimate.

I have since flushed my system and done a completely fresh install of Windows 8.1 Pro, VS2010 Ultimate, VS2012 Ultimate, & VS2013 Ultimate.

Same test done on all 3 versions of VS - File > New Project > MVC (Default). All 3 versions of VS are reporting "Process with an Id of xxx is not running."

VS2013 debug trace reports "The program '[7720] iisexpress.exe: Program Trace' has exited with code 0 (0x0). The program '[xxxx] iisexpress.exe' has exited with code -1073741816 (0xc0000008) 'An invalid handle was specified'."

I have run VS in and out of Administrator mode and receive the same results. I have uninstalled and reinstalled IIS Express 8.0.

The Best Answer is


For me the solution was a much simpler one. In my Solution Explorer in Visual Studio, I right click on the web project, chose properties and then navigated to the "web" tab. From there I changed the Project URL to another port number. For example, if it was http://localhost:1052 - I changed it to http://localhost:4356.

Process with an Id of xxx is not running.

Not sure if this helps anyone else, but it worked for me - hopefully it will work for you too!

If you are using 64 bit machine

Go to Visual Studio > Tools Menu > Options

Options window with Projects and Solutions > Web Projects selected and option Use the 64 bit version of IIS Express selected
