An ASP.NET Core web application is a client/server application in which a client interacts with a web server using a browser. The logic of the web application is distributed between the server and the client, the data is stored mainly on the server, the exchange of information occurs over the network.

One of the benefits of this approach is that clients are independent of the specific operating system of the user, so web applications are cross-platform services. The web application itself can act as a client for other services, such as a database or another web application located on a different server. A striking example of a web application is the content management system for Wikipedia articles: many participants can jointly create an online encyclopedia using the browsers of their operating systems (Microsoft Windows, GNU / Linux or any other operating system) and without downloading additional executable modules to work with the base articles.

Ajax’s approach to web application development is popular now. When using Ajax, the pages of the web application are not reloaded entirely, but only reload the necessary data from the server, which makes them more interactive and efficient. WebSocket technology is also very popular. It does not require constant requests from the client to the server but creates a bi-directional connection in which the server can send data to the client without a request from the latter. Thus, it becomes possible to dynamically manage content in real-time.

Xamarin apps – a popular cross-platform app development tool for iOS, Android, tvOS, watchOS, macOS, and Microsoft (UWP apps) in C # and .NET. In recent years, it has consistently ranked among the five most-used frameworks by developers.

Games on the Unity platform – a cross-platform game development environment based on .NET and developed by the American company Unity Technologies. Unity allows you to create applications that run on over 25 different platforms, including personal computers, game consoles, mobile devices, and web applications.

Desktop applications based on .NET technologies WPF and Windows Forms are programs whose logic requires an operator (a person working with the program). They contain all the full functionality and are able to work separately on any machine in isolation from other applications. Microsoft Word, Excel, Notepad, single-player games are all examples of desktop applications.

For their operation, only sufficient computer hardware resources, the application itself, and a set of libraries containing functions for working with the application are required.

Desktop applications can also be multi-user. For example, a file editor, which, depending on the login and password entered at startup, will give access to various files. Both the program and the files are located on the same computer, it is just that local access control is performed for different users.

Microsoft Azure cloud services are programs and platforms that “live” and run on the servers of cloud providers. Cloud storage is provided to the user in the required amount, is paid on a per-use basis, and eliminates the need to buy and manage your own IT infrastructure for data storage. This provides flexibility, fast scalability, and reliability.
