Fixing the ASP.NET 5 and MVC 6 debugging issue with IIS Express in Visual Studio 2015 Update 1

When debugging the new ASP.NET 5 and/or ASP.NET MVC 6 web applications, you receive the following error message:

Microsoft Visual Studio
The selected debug option is IIS Express but this project is not a web project.
To use IIS Express you need to add the wwwroot attribute to project.json.

This fix this issue, you need to modify your project configuration file. Here's the solution: edit project.json, and add the following entry:

...
  },
  "webroot": "wwwroot"
}

This will instruct IIS Express to load your project correctly, and Visual Studio to be aware that this is indeed a web project that can be run (and debugged) locally.

Hope this helps!
