This feature is currently planned to be included in EF7.Kieron Dye commented
Unfortunately the identifying relationship is not always possible. From my understanding to make the identifying relationship work you have to make the foreign key part of the primary key. We have a scenario where the child has derived types. The derived type tables have the child key but do not have the parent key and so modifying the child to use the parent key in its own primary key breaks the inheritance. Presumably this would also be a problem if the child had children.

We plan to implement type conversions in the EF Core codebase. It is not committed to be part of 1.1 although it is one of three post-1.1 features we will start working on soon. See https://blogs.msdn.microsoft.com/dotnet/2016/07/29/entity-framework-core-1-1-plans/ for more details on 1.1 priorities. Also the bug tracking this work is https://github.com/aspnet/EntityFramework/issues/242.
