Few days ago the Entity Framework 6 jumped into RC stage. FirebirdClient has already support for Entity Framework 6, but I was waiting for some “significant” (as RC ;)) stage to start pushing it more except for publishing the build on FirebirdSQL.org site.
Thus without further talking let me introduce FirebirdSql.Data.FirebirdClient-EF6. It’s the same version as FirebirdSql.Data.FirebirdClient except build for Entity Framework 6 (though no dependency on EntityFramework package is there - you’ll be able to use it without it).
Enjoy. And report any issues you find.
