I've Visual Web Developer 2008 Express installed on my PC,
Does ASP.NET MVC3 works in visual web developer 2008 express?
How to create simple ASP.NET MVC3 site using simple text editor?
No, it doesn't work. ASP.NET MVC 3 requires .NET 4.0 and VS 2008 doesn't support .NET 4.0. You could use Visual Studio 2010 Express.
You can install Visual Studio 2010 Express alongside VS2008 - you do not need to uninstall VS2008, and it will not break your VS2008 configuration.
This will be your best option.
