Maybe it's my mistake, just switched the target framework to 4.5 the designer gives no error, targeting framework 4 gives the 3 errors listed above

Error 1 Error 10027: The XML namespace for the conceptual model's Schema element is not supported on this project's target framework version. C:\Code\tmp\EDMX\ConsoleApplication1\ConsoleApplication1\Model1.edmx 47 7 ConsoleApplication1
Error 2 Error 10028: The XML namespace for the storage model's Schema element is not supported on this project's target framework version. C:\Code\tmp\EDMX\ConsoleApplication1\ConsoleApplication1\Model1.edmx 7 7 ConsoleApplication1
Error 3 Error 10029: The XML namespace for the Mapping element is not supported on this project's target framework version. C:\Code\tmp\EDMX\ConsoleApplication1\ConsoleApplication1\Model1.edmx 91 7 ConsoleApplication1

Thanks, Max
