The provider did not return a ProviderManifest instance (VS 2013, EntityFramework 6)

checking out EntityFramework 6 code-first and encountering various errors during the process :)

this is more of a saved hint how to deal with this...found in the comments here:
https://connect.microsoft.com/VisualStudio/feedback/details/806693/the-provider-did-not-return-a-providermanifest-instance-in-vs-2013-and-entityframework-6

this comes with the inner exception of "Could not determine storage version; a valid storage connection or a version hint is required"

and what solved it was this comment:

Open the EDMX file and change ProviderManifestToken="2012" to ProviderManifestToken="2008"

judging by MS supports' comment, Microsoft seem terribly slow in keeping tools up to date with frameworks...whats the point in rushing when creating ugly problems for (early) adopters?
