Support for NoSQL database providers such as Azure Table Storage, Redis and others (like MongoDb) are still in EF Core team backlog and has not been implemented yet and will not be implemented for Core 1.0.0 release.
That said, according to the EF Core Roadmap, support for NoSQL Database providers is a high priority feature for the team and will be shipped in the future releases after Core 1.0.0 release.
