By pooling, DbContext objects are created once, then reused when needed. Entity Framework is responsible for opening a connection to the database, and can subsequently perform read/write actions on the dataset via interacting with items in a given DbSet. EF Core is an Object/Relational Mapping (O/RM) framework for .NET applications that developers use to access a database. The framework is an enhancement to ADO.NET that provides developers with an automated way to access and store data in a database. It is the representation of the database design such as tables, views,
relationships with the keys, and stored procedures.
I met a lot of issues with EF on different projects with different approaches. If you’re experiencing performance issues with Entity Framework, there what is entity framework are a few common workarounds that can help. So if you’re dealing with a complex database schema, don’t worry – Entity Framework has got your back.
What is Entity Framework? Why we use it?
The essence of Entity Framework is that it is a set of technologies that can support the development of data-oriented software applications. This is an open-source object-relational mapping (ORM) framework in ADO.NET. Optimizing performance is also crucial when working with Entity Framework and LINQ queries. One way to improve performance is by reducing the number of database roundtrips needed. This can be achieved through techniques such as eager loading, which loads related entities along with the main entity in a single query instead of multiple queries. On the plus side, EF can simplify your code by providing automatic mapping between your database tables and your object model classes.
Entity Framework Core, on the other hand, has better ease of use, security, and code maintainability, but may not perform as well in some scenarios. Audacia is a leading UK software development company who specialises in building scalable and robust, business-critical software systems. At Audacia, we’re constantly looking at ways we https://deveducation.com/ can improve our new and existing applications. Features like Compiled Models would be a great incentive for a large application to upgrade to .NET 6, and demonstrates Microsoft’s appetite for continuous improvements. The selected project was one with over 300 entities, the vast majority of which correspond to its own table in SQL.

In EF Core, the N+1 problem can occur when you’re trying to load data from two tables having a one-to-many or many-to-many relationship. For example, let’s say you’re loading author data from the Authors table and also book data from the Books table. You can significantly reduce the number of round trips to the database by avoiding the N+1 selects problem.
- In this article, we will explore 10 tips and tricks or strategies we can use in EF Core to improve the data access performance of our .NET Core applications.
- Microsoft has provided an open-source ORM (Object-Relational Mapping) framework for ADO.NET called “Entity Framework” which automates the activities related database.
- Some of the commands we’ll be running in this video include dbcontext scaffold, migration add, and database update.
- As per the above figure, Entity Framework fits between the business entities (domain classes) and the database.

I have always been taught that you work from the ground up, get your foundations right and everything else will follow. I know there are challenges in naming convention etc, but I feel its very confusing to manage Code First as everything looks like code and its too much to code either. It’s important to weigh the pros and cons carefully before making a decision.
Let’s dive into the exciting world of LINQ and explore its powerful capabilities for enhancing your development skills! LINQ, or Language Integrated Query, is a set of technologies in .NET Framework that allows you to query data from different data sources using a consistent syntax. With LINQ, you can easily interact with various types of data such as objects, databases, XML files, and more. Instead of writing complex SQL queries or traversing through large collections manually, you can use the LINQ syntax to filter, sort, group and transform data effortlessly. Entity Client is the core layer in Entity Framework, which connects the data source layer to the Object Service layer with the help of providers.
