Highlights

Learning videos

  • Excellent new video series from Cam Soper focused on introducing EF Core to new developers.
  • Earlier today was the Let's Learn .NET: Data event. We built a Web API using EF Core from scratch. If you missed it live, then catch it on-demand.

EF7 Progress

  • Work on lifecycle hooks (events and interceptors) is now underway
  • Further performance improvements for SaveChanges have been merged

EF7 Cuts

A combination of factors have resulted in a reduction in available resources for EF7. This means we have had to cut or scope some planned work. This includes:

In addition, some smaller enhancements have also been cut. For a complete list, see issues labeled with punted-for-7.0 in the EF GitHub repo.

Community Standup: Performance Improvements to the EF7 Update Pipeline

Join the Entity Framework team as we review optimizations to the update pipeline (SaveChanges) to improve performance. Also includes answers to many performance questions asked during the live show.

Community Standup: EF Core Architecture--Internal Dependency Injection

Arthur and others from the EF Team start a deep dive into the architecture of Entity Framework Core. This code-driven discussion looking at how and why things are designed and implemented the way they are. In this session, we look at the use of dependency injection (D.I.) and the “internal service provider.” This is the backbone of how EF Core works as a service-oriented architecture, where the core code, database providers, and plugins all implement services that work together to provide EF’s functionality.

Community Standup: TPH, TPT, and TPC Inheritance mapping with EF Core

Type inheritance hierarchies as used in object-oriented programming do not map naturally to relational database schemas. In this edition of the .NET Community Standup, we look at different strategies for inheritance mapping when using EF Core with a relational database. This includes table-per-hierarchy (TPH) mapping, table-per-type (TPT) mapping, and table-per-concrete type (TPC) mapping, which is new in EF Core 7.0 preview 5. We explore the consequences of each mapping strategy on the generated SQL and consider the performance and storage implications.

Highlights

Unfortunately, we have had to make some painful cuts to the EF7 plan. Most notably, value objects and raw SQL queries for unmapped types have been cut. These will be a high priority for the next release.

In better news, all interceptors and events for EF7 are now in the daily builds. This includes new interceptors for:

  • Entity materialization
  • Query expression trees
  • Identity resolution in Attach
  • Optimistic concurrency violations
  • Constructor bindings

And improved interceptors for:

  • DbCommand
  • DbConnection
  • DbDataReader

Plus better state change events and new events for DetectChanges.

Highlights

Introducing the new .NET Data Hub!

The Data Hub is a new landing page bringing together everything related to data handling in .NET. Feedback on organization or anything missing is appreciated.

Meanwhile, the team is working hard to land .NET 7 and EF7 features, including Distributed transactions, JSON columns, Bulk updates, stored procedure mapping, Database scaffolding templates, and Entity splitting.

Community Standup: DbDataSource--a new System.Data abstraction

In this episode of the .NET data community standup, Shay Rojansky explores DbDataSource, a new abstraction being introduced to System.Data in .NET 7.0. DbDataSource unlocks easier integration of ADO.NET drivers with dependency injection, better management of advanced driver configuration, helps performance and more.

You can watch all .NET Data Community Standups on YouTube. We live-stream every other Wednesday to Twitch, YouTube, and Twitter. Comment on GitHub with ideas for guests, demos, or anything else you want to see.

EF Core 7.0

.NET 8 Data and EF8

We've started the process of planning for EF8 and other .NET Data work for .NET 8. See Release Planning for an overview of the planning process.

Community Standup: JSON Columns

This episode of the .NET Data Community Standup covers JSON column mapping in EF Core 7.0 (EF7). JSON columns allow relational databases to directly store documents while retaining the overall relational structure of the data. EF7 contains provider-agnostic support for JSON columns, with an implementation for SQL Server. The JSON in these columns can queried using LINQ, allowing filtering and sorting by the elements of the documents, as well as projection of elements out of the documents into results. In addition, EF7 supports element-level change tracking of the documents and partial updates for only the changed elements when SaveChanges is called.

You can watch all .NET Data Community Standups on YouTube. We live-stream every other Wednesday to Twitch, YouTube, and Twitter. Comment on GitHub with ideas for guests, demos, or anything else you want to see.

Highlights

.NET 8 and EF8

The team is hard at work planning for EF Core 8.0 (EF8) and other data work in .NET 8. As always, we will share the plan publicly as soon as we can.

Analysis of EF Core bugs

Meanwhile, we have been looking back historical data on fixing bugs in the EF Core repo. A couple of charts are included below for anyone interested.

Note: This data is specifically about bugs, and does not include enhancements or feature requests.

Open and fixed bugs

We strive to fix the vast majority of bugs. That is, if we recognize something as a reproducible bug, then we very rarely close it as "won't fix". The chart below shows the number of bugs filed over time, with those remaining open in blue, and those fixed in orange.

Open and fixed bugs

Time to fix bugs

The second chart shows the amount of time it takes to fix a bug. That is, the time from when it is opened on GitHub, to the time when the fix is merged into the main branch.

Community Standup: ExecuteUpdate and ExecuteDelete (aka Bulk Updates)

EF Core 7.0 introduces the ExecuteUpdate and ExecuteDelete APIs, which allow you to easily use LINQ to express a database update or delete operation. These APIs can be far more efficient for applying changes to multiple rows based on a condition, e.g. “delete rows which have InActive set to true” (AKA bulk update scenarios). But in some scenarios, they also allow you to express changes over a single row in a much more succinct and simple way, simplifying your code. ExecuteUpdate and ExecuteDelete completely bypass EF’s change tracking and execute immediately, as opposed to when SaveChanges is called. Watch the latest episode of the .NET Data Community Standup to learn more and to explore the new possibilities that these new APIs bring!

You can watch all .NET Data Community Standups on YouTube. We live-stream every other Wednesday to Twitch, YouTube, and Twitter. Comment on GitHub with ideas for guests, demos, or anything else you want to see.

.NET Conf 2022 sessions

Leveling up data: Upgrade from EF6 to EF7 and blast off!

Video link

Arthur Vickers, Shay Rojansky

In this code-heavy session, Arthur and Shay from the .NET Data team take an Entity Framework 6 application running on .NET Framework 4.8 and upgrade it to Entity Framework Core 7 running on .NET 7. After the upgrade, queries run faster and the roundtrips needed to save data are massively reduced. We’ll then use several new features from EF7, including bulk updates to further boost performance, and querying into JSON embedded in a column. Join us to take your EF apps out of this world!

T4 goodness with Entity Framework Core 7

Video link

Erik Ejlskov Jensen

In EF Core 7 you can now use T4 (text template transformation templates) to customize the Database First workflow. In this session you will get an overview of this new feature and see some simple customizations.

EF Core 7 (EF7) is released!

.NET 8 and EF8

The team is hard at work planning for EF Core 8.0 (EF8) and other data work in .NET 8. As always, we will share the plan publicly as soon as we can.

Community Standup: EF7 Custom Model Conventions

EF Core uses a metadata "model" to describe how the application's entity types are mapped to the underlying database. This model is built using a set of around 60 "conventions". The model built by conventions can then be customized using mapping attributes (aka "data annotations") and/or calls to the DbModelBuilder API in OnModelCreating. EF7 allows applications to remove or modify existing conventions, as well as create new conventions. On this .NET Data Community Standup, we learn how to take advantage of custom model building conventions in your EF Core 7.0 applications.
