Entity Framework has less code to fetch the records from database, which makes the code easier to maintain. This is helpful in large-scale applications as it provides a clear structure of the mapped relational objects and the dependent layers. Hence, Entity Framework is a powerful ORM tool which is easy to understand and implement. With the help of entity framework, it is quite convenient to develop secure, scalable & robust enterprise mobile application development.
This framework not only simplifies the complexity inherent in data manipulation but also enhances productivity by seamlessly integrating with the Visual Studio IDE. Its design promotes a cleaner, more maintainable codebase through abstraction and encapsulation of database operations. When considering whether to use Entity Framework or another data access approach, it’s crucial to weigh these advantages and disadvantages against the specific needs and requirements of your application. Often, the decision involves balancing development speed, maintainability, and performance trade-offs based on the project’s context and goals. If you are a .NET developer then you would be familiar as you might be using or have used ADO.NET code in your application for data access. For all those who are new to this word, ADO.NET is a set of software components in a computer which is used by the developers to access and modify the data stored in the relational database systems.
Model-First
From the solution folder, we can run the following dotnet command. Knowing that EF Core is different, I took some time to explore the EF Core documentation and determine the existing pitfalls you might encounter when starting your EF Core journey. I’ve compiled and consolidated this information to help you get a general overview of potential mistakes you may encounter. Its very common to have a Entity generator code tool to generate the enitites.
- Effective query optimization techniques can significantly reduce the load on the database, ensuring smoother and faster operations.
- As a final word, the new enhancements to EF Core embrace the database and SQL more than ever, which is why its important that we learn all we can about the database we’ve chosen.
- We can also selectively scaffold parts of an existing database by specifying table names.
- Furthermore, staying informed about potential breaking changes with new updates and versions of Entity Framework is necessary to avoid unexpected issues.
- Production is a little less reliable when it comes to connection reliability.
- The conceptual leaks are not bad, but they are something to be mindful of as we start using features like DbFunction and FromSql to execute database-engine-specific features.
Seamless integration with LINQ (Language Integrated Query) allows developers to write type-safe queries using C# or VB.NET, providing compile-time checking. All in all we can say entity frameworks are good for small range of applications. But if we overcome the drawbacks of EF it will be perfect for any type of applications. Closely related to reducing development time (above), applications are less expensive to develop because the architects of data-oriented applications spend less manhours building the applications. We can opt into identity resolution while opting out of object tracking by using the newly added AsNoTrackingWithIdentityResolution method. To install the tool locally for each solution, we first need to create a tool manifest.
Storage Model
Entity framework enables the developer to focus on the domain objects and its core working rather than the architecture of database. Entity Framework’s versatility shines through its robust compatibility and seamless integration with multiple database providers, including SQL Server, MySQL, Oracle, and PostgreSQL. This adaptability facilitates a more streamlined development process, as it supports a wide range of database systems out of the box. Such compatibility ensures that developers can easily switch between different database providers as project requirements evolve, without the need to overhaul the application code. This feature not only saves time but also significantly reduces the potential for errors during the transition process.
EF updates and new versions might introduce breaking changes, requiring code updates or modifications in existing applications. Complex queries might not be efficiently translated into SQL, leading to suboptimal database queries. Writing raw SQL might be necessary for certain complex scenarios. EF might introduce performance overhead due to abstraction layers, resulting in slightly slower performance compared to hand-tuned SQL queries in some scenarios.
EF Core Database Providers
We can also selectively scaffold parts of an existing database by specifying table names. The Entity / 3 layers framework concept, has been out there for a while, and have work with several custom libraries, like many other developers, before Microsoft released its own “official” framework. The following figure illustrates the supported application types, .NET Frameworks and OSs. In conclusion, the Entity Framework provides a significant advantage in streamlining development processes, offering seamless integration capabilities, and ensuring type safety through LINQ. Both ADO.NET and Entity Frameworks have similar and quite different features. To make the process of comparison easier and to answer numerous questions about them (e.g. “does Entity Framework use ADO.NET?” etc.), we offer a clear comparison table.
Since EF Core is no longer tracking entities, EF Core will allocate an entity for the same Actor multiple times. Some folks may want to test against a different engine, for instance SQL Server might be the target database engine, but tests run against a SQLite instance. While possible, this approach leads to more problems like SQL syntax differences and having to manage a different migration strategy entirely.
Connection resiliency
Storage model is basically the design model of the database which comprises of tables, views, stored procedure, their keys & relationships. As a final word, the new enhancements to EF Core embrace the database and SQL more than ever, which is why its important that entity framework meaning we learn all we can about the database we’ve chosen. Understanding a database engine’s inner-workings and the particular SQL syntax will give developers the most significant advantage, as developers can use that knowledge to optimize around any EF Core limitations.
Another potential solution is to use an alternative Entity Framework Library that is not the one supplied with V.S. Entity Framework Core is the new and improved version of Entity Framework for .NET Core applications. To expand your possibilities, you can use this powerful Entity Framework Designer that automates the process. I am a skilled Microsoft .NET Developer with 7+ years of experience in software development. It eliminates much of the repetitive and boilerplate code required for CRUD (Create, Read, Update, Delete) operations, making codebase cleaner and more maintainable.

The TPH approach uses a single table with columns for each property unique to an entity with a Discriminator column. In the following example, both Movie and Series share a Productions table. All instances of the same Actor model will point to the same object, thus saving us from over-allocating. We must specify the appropriate database provider when scaffolding so that the scaffolding can respect the SQL syntax of our database.
Sometimes we can fix these issues through infrastructure management or by optimizing queries to be less taxing on our database. I personaly would normally use the entity framework for new development but not rewrite working existing code. You then get the speed for future delelopment but dont have to invest lots of time converting code.
Given EF Core’s LINQ interface, it’s tempting to do all our operations using our C# entities. When dealing with large dataset operations, it is better to embrace the underlying data storage engine rather than LINQ our way through thousands of records. This repeated data can lead to what’s known as a Cartesian Explosion if there are enough tables involved within a query. Using the model builder interface to combine columns should add to the efficiency of SQL queries. When using inheritance, we usually define shared properties on base types, but there might be an instance where that’s not the case. Let’s look at an example where two models in our hierarchy share the same property name without inheriting from the base type.
