## Major areas While engineers frequently work on multiple things in parallel, these are the high-level areas that we are focusing on for the EF Core 3.0 release. ### Query pipeline overhaul What: The way LINQ queries are translated is getting a major overhaul for EF Core 3.0. Part of this involves removal of automatic client evaluation, except in the final projection. Status: * We are preparing to merge the new pipeline in the next couple of weeks. * Not everything will be working at that time, but merging will allow us to start gathering feedback. * This will likely first ship in EF Core 3.0-preview6. Tracking issue: https://github.com/aspnet/EntityFrameworkCore/issues/12795 ### Porting EF6 to .NET Core What: Support EF6 on .NET Core. Status: * We plan to ship a runtime targeting .NET Standard 2.1 with .NET Core 3.0-preview5. * Command line tooling (for Migrations) and support in the VS Designer is not yet ready to ship. Tracking issue: https://github.com/aspnet/EntityFramework6/issues/271 ### Provider model updates What: We are promoting some internal types and concepts to public so that they can be consumed safely from database providers. Status: * Most changes here have already been merged. * Changes related to the query overhaul will be addressed after the merge of that work. * Public API surface for conventions is being work on. Tracking issue: https://github.com/aspnet/EntityFrameworkCore/issues/15405 ### Breaking changes What: We are making a number of breaking changes for EF Core 3.0 to improve the experience and functionality of EF Core in various important ways. Status: * Many of the planned breaking changed have now been merged * Remaining planned breaking changes are mostly around the query overhaul and provider model updates * Breaking changes, including mitigations, are documented in the [EF Core breaking changes doc](https://docs.microsoft.com/en-us/ef/core/what-is-new/ef-core-3.0/breaking-changes). Tracking issue: https://github.com/aspnet/EntityFrameworkCore/issues/15407 ### Cosmos database provider What: We are continuing work on the EF Core database provider for Azure Cosmos. Status: * Work is currently on hold while provider-model and breaking changes are being made Tracking issue: https://github.com/aspnet/EntityFrameworkCore/issues/12086 ## Highlights from the last week Some items of interest from the last week: * **We released EF Core 3.0 Preview 4!** Read more details in [our announcement blog post](https://devblogs.microsoft.com/dotnet/announcing-entity-framework-core-3-0-preview-4/). * We have [updated the internal code API docs](https://github.com/aspnet/EntityFrameworkCore/issues/15235) to better convey the dangers of using internal code without saying that it should never be used. * The `dotnet-ef` command [has been removed from the SDK](https://github.com/aspnet/EntityFrameworkCore/issues/14016) and must be installed explicitly. This aligns with removing EF Core from the ASP.NET Core shared framework. * The [`DeleteBehavior` enum has been updated](https://github.com/aspnet/EntityFrameworkCore/issues/12661) to make it more consistent and understandable. * Documentation for [the nightly builds](https://github.com/aspnet/EntityFrameworkCore/issues/15100) has been updated to make them easier to find and use. ## More Information See the top of this issue for links to more information.
