For more advanced features, users of .NET Core can utilize NuGet packages, which can be added to the apps as-needed. Therefore, the .NET Core app can make the functioning of the app quicker, decreasing its memory footprint, and increasing the app’s serviceability and maintainability.


In the eventuality that you decide to assemble an app, and should you choose either .NET framework or .NET Core, the latter would be the better choice. This is due to certain characteristics of .NET Core, such as more qualification for multiplatform requirements and the more effective building of microservices. Also, it is possible to implement Blazor for the creation of client user interfaces with the help of .NET.

It is important to note that beginning from version 5, there is no .NET Core anymore, as the .NET name serves as its substitute since that time.

There is also an interesting tool named Universal Windows Platform that is of great help to the engineers that work in this field. It is a robust instrument used to build client apps on Windows. With its help, engineers can create feature-rich UIs, enhanced with great asynchronicity – perfect for devices connected to the internet. The tool is based on .NET Standards, a common set of APIs that replace portable class libraries. However, the new release of MAUI is far more popular at the moment.

The .NET framework has some restrictions. For example, it can only work for Windows-based platforms and software engineers need to utilize various APIs for different devices or gadgets. Moreover, any kind of adjustments made to this platform can influence all of the apps that are dependent on it.

Therefore, .NET Core often seems to be a better solution. For modern heavy-load projects, it is necessary to have an app that can run across various devices. This being said, .NET Core proves to be a great tool for desktop development, as well as web and mobile-oriented apps that are convenient to use both for developers and users.

The main aim of .NET Core was to add new features of open source, multiplatform frameworks that can be used for multiple purposes in diverse scenarios, varying from huge data centers to compact portable tablets.

What Is .NET 5?

.NET 5 is a platform-agnostic open source framework that is suitable for the creation of numerous types of apps. In its naming, there is no “Core,” which implies that the very concept of .NET 5 represents the future of all previous releases of .NET Core. According to many specialists, .NET 5 will eventually take the place of Xamarin and .NET Core, being the one united platform which possesses up-to-date .NET coding and API. As a matter of fact, .NET is essentially the amalgamation of the two platforms — .NET Framework and .NET Core.


Let’s consider the peculiar features of .NET 5. Having .NET Core and .NET Framework as its predecessors, .NET 5 has the aim to offer a platform-agnostic approach to development and truly revolutionary opportunities with the microservices architectural view. It is a great choice when you aspire to create a performant multiplatform solution that can be subsequently scaled.

First of all, .NET 5 gives the chance of using unified platform for .NET. It means that .NET 5 offers a number of APIs that can align various runtime usages. Thanks to this peculiarity, the app can run on any runtime implementation that supports .NET 5.

Nevertheless, there is still an opportunity to create a .NET 5-based app for specific platforms. This level of unification in .NET 5 was achieved with the help of thorough architectural restructuring. Although several features were eliminated, the platform experienced tremendous enhancement as a result.

Then, let’s consider what’s new with C# in .NET 5. The most notable innovations led to enhanced performance and speed due to numerous valuable adjustments, including:

  • top-level statements
  • record types
  • Init setters.

Another significant enhancement of .NET 5 is its innovative way to create platform-agnostic UIs within one project. What is more, MVVM pattern offers effective management of updating and app state control in .NET 5. Also, .NET 5 supports apps that engineers publish and deploy in the form of single files.

These types of apps enjoy innovative internal structures and can be executed without performance slowdowns. Such opportunity was present before as well, but in .NET 5 it underwent significant improvement which resulted in better performance.

Since the objective of .NET 5 was to realize the idea of a truly multiplatform framework, a number of old features had to be eliminated. For example, there are no web forms anymore in .NET 5. However, there is another way to create user interfaces in .NET 5 using such tools as Blazor framework or Razor Pages web application programming model.

.NET 5 gives the opportunity to create a variety of applications with multiplatform characteristics. The most widespread use cases of implementing .NET 5 are:

  • cloud services;
  • websites;
  • platform-agnostic apps;
  • microservice architectural approach;
  • Docker containers;
  • high-performant scalable applications;
  • mobile apps;
  • Windows-based desktop apps;
  • multiplatform console apps;
  • UWF;
  • WPF;
  • Data Science;
  • AI, ML.

.NET Core is suitable for creating apps on a variety of platforms and cloud apps. This instrument is great when the .NET team aspires to refactor huge enterprise-level apps with the help of the microservice architecture of .NET Core. Visual Studio is compatible with Windows and has a limited version for macOS.

.NET Core lets developers utilize a mixture of functionalities and create solutions that can be easily scaled afterward. Thanks to its modularity and scalability, .NET Core can work perfectly with Docker containers. .NET 5 has the same features as well.
