ASP.net MVC2 project in VS2012 not working

Question

Is it possible to open MVC2 project in Visual Studio 2012? When I try to load the project I get this error :

De\De.csproj: The application which this project type is based on was not found. Please try this link for further information: http://go.microsoft.com/fwlink/?prd=12395&pver=11&sbp=ProjectTypeDeprecated&plcid=0x409&clcid=0x409&ar=MSDN&sar=ProjectCompatibility&o1=F85E285D-A4E0-4152-9332-AB1D724D3325

Then I get redirect to : http://www.asp.net/whitepapers/mvc3-release-notes#upgrading

Do I need to upgrade to MVC3 or I can keep my project in MVC2?

I ended up re-building the application and importing all my class and views — VinnyG

sorry that you ended up rebuilding your project. Wish I had run into this issue earlier so I could have provided you with this answer: stackoverflow.com/a/13424080/61654. — ahsteele

At VinnyG's request I am providing a link to an answer I provided on how to fix this issue. The linked answer provides a fully detailed solution but here is a summary:

ASP.NET MVC 2 will need to be downloaded and installed. The MVC 2 project file will need to be modified removing its project GUID. The removal of the project GUID will mean that the project no longer behaves like an MVC project: no right click to add view, controller, etc., but will compile and work as an MVC 2 project without having to migrate.

Although this seems useful for a lot of people, in my case it didn't work. I used the <ASP.NET MVC 3 Application Upgrader> instead and that worked for me! Here you have the link: aspnet.codeplex.com/releases/view/59008

I'm interested in finding how an extension could be made to VS2012 to natively handle MVC2 projects like it does for MVC3+. At this time we wouldn't like to risk breaking anything upgrading 2-3 and having to test.

Copied from http://msdn.microsoft.com/en-us/library/hh266747.aspx

If the Model-View-Controller (MVC) project uses version 3 or 4, you can open this project in Visual Studio 2012. By default, Visual Studio 2010 with SP1 supports only MVC 2 and 3, and Visual Studio 2012 supports only MVC 3 and 4. For information about how to automatically upgrade from MVC 2 to MCV 3, see ASP.NET MVC 3 Application Upgrader. For information about how to manually upgrade from MVC 2 to MVC3, see Upgrading an ASP.NET MVC 2 Project to ASP.NET MVC 3 Tools Update. If your project targets the .NET Framework 3.5 with SP1, you must retarget your project to use the .NET Framework 4.

the application upgrader is not working once you try to open the solution in VS2012

the application converter tells me that it does not know what is the project type so I will have to do the conversion manualy
