The powerful and efficient systems behind modern web and mobile applications are built using back-end frameworks . These frameworks help developers create functional and secure applications, simplify coding, and improve user experience by completing projects faster. ASP.NET Core (.NET 6) and Entity Framework (EF) are some of the modern technologies used, and each plays a very important role in its own field.
ASP.NET Core
ASP.NET Core is an open source, cross-platform, high-performance web application back-end framework developed by Microsoft. .NET 6 is one of the latest versions of ASP.NET Core . ASP.NET Core is used to create web applications. This framework allows you to create both websites and APIs (Application Programming Interfaces). This back-end framework can run on different operating systems such as Windows, Linux, and macOS.
The main advantages of developing with ASP.NET:
Less coding required. Back-end developers write fewer statements and can rely on ASP.NET Core 's pre-configured features, which speeds up application development.
Cross-platform. The same C# code base provides a smooth and predictable user experience across multiple major platforms.
Optimizing applications is easy. Experienced .NET developers can optimize the Core back-end framework with just a few statements to ensure application performance and maintainability.
Possible difficulties with ASP.NET:
Vendor lock-in. Because Microsoft controls the .NET framework, developers have less freedom of movement and must adhere to restrictions imposed by Core developers.
Licensing . Unlike a fully open source back-end framework, some core modules, such as Visual Basic, require a license fee. These costs can quickly add up when more advanced functionality is required.
Areas of use:
Creating websites.
Building RESTful APIs and Web APIs.
Working with Microservices architecture.
Creating interactive web applications with Blazor.
.NET 6
is called the .NET 6 unified platform. That is, .NET 6 is a common platform that can be used to create web applications, desktop applications, mobile applications, and other types of applications. ASP.NET Core is part of .NET 6. .NET 6 also works with programming languages such as C#, F#, VB.NET and has cross-platform support. .NET 6 is a long-term support (LTS) version that follows previous .NET Core versions and is recommended for new applications.
Entity Framework (EF)
Entity Framework (EF) is an Object-Relational Mapping (ORM) back-end framework developed by Microsoft. ORM allows you to use object-oriented programming (OOP) principles to work with databases. That is, Entity Framework converts data stored in the database into objects, making the program easier to work with.
Entity Framework Core (EF Core) is an ORM tool that works in conjunction with ASP.NET Core . With EF Core, it is possible to send queries to the database, read, write, delete and update data. EF Core handles this automatically through LINQ (Language Integrated Query), which reduces the need to write SQL. However, in some complex queries or situations that require special optimization, SQL statements may be needed. It simplifies and speeds up the process of connecting to the database.
Areas of use:
Working with databases (SQL Server, PostgreSQL, MySQL, etc.)
Manage database operations (CRUD – Create, Read, Update, Delete) in an object-oriented manner.
Migrating database structures (automatically creating and updating the database model from code).
Advantages of a back-end framework
Time savings.
When developers can create application functionality using small pre-written functions, the development process takes less time. This also leads to fewer errors, which ultimately increases the quality of the product.
Scalability.
The back-end framework's functionality is pre-tested and can be scaled quickly and easily. This makes it easy to build an application that can adapt to demand growth and scale up or down components as needed.
Robustness.
With a framework, you can use and extend existing code. This allows developers to create robust functionality, provide clear and simplified structures, and avoid the need to write anything new.
Security.
Most of the frameworks used in the back-end are open source and have a large community behind each one, so security issues are adequately addressed. World-famous sites and applications such as Instagram, Pinterest, Shopify, Coursera, and Reddit are built using Django, Ruby on Rails, Laravel, Node.js, and ASP.NET . These companies adhere to high security standards.
Integrations.
Instead of creating a standalone application, it is more practical to enrich an existing application with new features. Back-end development frameworks make it easier to integrate RESTful APIs or GraphQL. This way, you can make your new application an integral part of a growing software ecosystem and significantly improve the user experience.а
