Upgrading WebForms .csproj to MVC

So you followed all the steps to upgrade your old ASP.NET WebForms project to ASP.NET MVC: added the necessary entries to the web.config, created a Views and Controllers directory, and added the necessary references. However, when you right click to add a new item to the Controllers directory (or Views directory) in Visual Studio 2008 there are no MVC items available. You need to update the .csproj view a text editor to "tell" it that it is a MVC project. Here is how: 1. Close out of Visual Studio. 2. Open .csproj file of the web site in notepad 3. In the beginning of file there is PropertyGroup block. Find the ProjectTypeGuids tag. 4. Add {603c0e0b-db56-11dc-be95-000d561079b0} as first project type GUID, the delimiter is a semi-colon. 5. Save the file . Now you can open the solution again in Visual Studio 2008 and you will have the MVC items. {6230289B-5BEE-409e-932A-2F01FA407A92}
