Close out Visual Studio completely, then check your system tray and stop any instances of IIS Express that might be running. Re-start Visual Studio, create a new MVC project based on one of the standard templates. Check the properties to ensure it's set to use IIS Express, and then run it. If you don't get the same error, check any custom code your might have in the troubled project's Global.asax.cs (or .vb) file. Put debug points on the first line of every method you have code in (Application_Start, etc.). Step over each line and see where it breaks.

If you don't have any custom code in there, close out VS and clean the ASP.NET temp directories. Do a restart, and see if the problem persists.

The problem seems to have been caused by AVG antivirus.

I was able to solve by uninstalling AVG antivirus.

Right click on your ASP.NET MVC project. Select 'Properties' option. Go to 'Web' settings and choose option 'Use Visual Studio Development Server' in 'Servers' category.

Now try to run the application, it will execute.

I had default chrome as a default browser and was getting the same issue while debugging. I changed the default browser in visual studio to Internet Explorer and then tried again. I was able to run my project successfully. Hope this may help.
