I am currently trying to import an EDMX file from EF6, targeting 4.7.2, using SQL Server 2014.

I've added '2014' as the Provider manifest token value, as well as tried 12.0 and nothing seemed to work. I am using v5.6 of LLBLGen

This is the error im getting

Inner exception message:

Exception type: ProviderIncompatibleException The provider did not return a ProviderManifest instance.

Inner exception message:

Exception type: ArgumentException Could not determine storage version; a valid storage connection or a version hint is required.

Issue was with the EDMX targeting 2012, changed it to 2008 and it fixed the problem. Seems weird that that would be the case.

Yeah that's a weird EF6 weirdness 2008 is indeed a token that works. I have no idea why 2012 doesn't work or that 2008 gives different settings internally...
