We also plan to work on the following features, but they may not be fully implemented in 2.0.
Update model from database (#831) - Allows you to incrementally update a model, that was previously reverse engineered from a database, with changes that were since made to the database schema. This allows you to update the model to match the current schema, without loosing any changes that were manually made to the model after it was reverse engineered.
Update: There are few minor reverse engineering features and fixes in EF Core 2.0.0-preview1.
