This late-bound or “weakly-typed” approach to data access is prone to error. Consequently, professional developers prefer to work with data in a strongly-typed manner. Entity Framework Core is a lightweight, extensible, open-sourced version of the Entity Framework Data Access Technology built for .NET Core Applications.
In November 2022, Entity Framework Core 7.0 has been released, and is now latest version available. Then based on the application domain classes and what is entity framework DBContext class, the EF Core creates the database and related tables. For a better understanding, please have a look at the following diagram.
Entity Framework Core in ASP.NET Core 3.1 – Getting Started
Entity Framework Core (EF Core) is a new, cross-platform, lightweight, and open-source version of Entity Framework that follows Entity Framework 6.x. The EF core current version is 6.0, released in November 2021. The version 4.3.1 was released on February 29, 2012.[10] There were a few updates, like support for migration. The following figure illustrates the supported application types, .NET Frameworks and OSs. Entity Framework is an Object/Relational Mapping (O/RM) framework. It is an enhancement to ADO.NET that gives developers an automated mechanism for accessing & storing the data in the database.
All you have to enter is the data type and the name of the property. That being said, DO NOT THINK that you can use only one way to access data in an application. Practical systems often use both RAW SQL and Entity Framework Core within the application. EFCore to query the data and perform quick operations, while Stored Procedures to perform complex, Bulk Updates.
The 2 Most Important Commands
As a result, EF Core 7 omits two round trips that were used in previous versions of EF Core to begin and commit a transaction. The upshot is that EF Core 7 provides a significant performance gain when inserting data into a database using a single insert statement compared to predecessors. If we want to execute the Entity Framework Core command from .NET Core’s CLI (Command Line Interface), first install the NuGet package Microsoft.EntityFrameworkCore.Tools.Dotnet using NuGet UI. This is an extra step we need to perform to execute the Entity Framework Core 2.0 commands from DotNet CLI in Visual Studio 2017.
First off, let’s create a .NET Core console application project in Visual Studio. Assuming Visual Studio 2022 is installed in your system, follow the steps outlined below to create a new .NET Core console application project. Entity Framework Core is not a part of the .NET core and standard .NET framework. Here we need to install the NuGet packages for the following two things to use Entity Framework Core in our application. It means that we have successfully added a new student record with id 1. We have successfully created the Student Database using the Code First Approach of Entity Framework Core in ASP.NET Core!
ADO.NET Providers
Because EF Core is adept at automatically loading related entities from the database when accessed by your code, lazy loading seems like a nice feature. Because DbContext objects may be costly to create and dispose of, EF Core offers a mechanism for pooling them. By pooling, DbContext objects are created once, then reused when needed.
- The answer is 100% a personal / enterprise culture choice.
- Forgetting to include important data can lead to panic when users think the system is not saving data or has deleted existing data.
- It eliminates the need for most custom data-access codes we usually write without an ORM.
- The risk becomes more dangerous if we were accepting user input in the form of a string parameter.
