Problem in opening ASP.NET mvc 1 projects in ASP.NET mvc 2

I cannot open a project built on ASP.NET MVC 1 in an MVC 2 environment. I get an exception saying 'The Project File xxxx.csproj cannot be opened. This proje开发者_开发百科ct type is not supported by this installation'. I can create a new MVC application though. I suspect this is due to the backward non compatibility of MVC 2 and 1, but am not sure. Please help.

You can open MVC1 projects but you need to delete a key from the project file:

You can also upgrade them with this tool:

hope this helps

Yes, MVC 2 is not seamlessly backward compatible.

You can have MVC 1 and MVC 2 installed side by side.

You can upgrade your MVC 1 project to MVC 2, see upgrading information.
