Manually converting a Visual studio project to include asp.net mvc Context menus

I’ve got a Visual Studio project that includes ASP.NET MVC controllers, models and view utilities but because it was not a Web Application I wasn’t getting any of the context menus for adding MVC elements. For example, ‘Controller’ was missing from the Add menu :

To fix this I unloaded the project, edited the csproj and added the following line :

<PropertyGroup>
    ...
    <ProjectTypeGuids>{603c0e0b-db56-11dc-be95-000d561079b0};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
    ...
</PropertyGroup>

Using a list of known project type guids I could identify the second guid which is Windows (C#) whilst the first I found by googling and checking a test ASP.NET MVC application I created with Visual Studio.
