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?

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.
