An Introduction to .NET MAUI For Mobile Development

.NET Multi-platform App UI (.NET MAUI) is a cross-platform framework for creating native mobile and desktop apps with C# and XAML.
.NET MAUI is open-source and is the evolution of Xamarin.Forms, extended from mobile to desktop scenarios, with UI controls rebuilt from the ground up for performance and extensibility. If you've previously used Xamarin.Forms to build cross-platform user interfaces, you'll notice many similarities with .NET MAUI. However, there are also some differences. Using .NET MAUI, you can create multi-platform apps using a single project, but you can add platform-specific source code and resources if necessary. One of the key aims of .NET MAUI is to enable you to implement as much of your app logic and UI layout as possible in a single code-base.

In this article we are going to discuss how to insert, update and delete data into database using ASP.NET MVC 4.0. There is a Layout page and Data base script that we are going to use for this but we are not going to discuss much  how to create a Layout page and database script here in detail. 

2021 was no exception and the following are some of the new areas where you’ll now find WebAssembly

• • The Disney+ Application Development Kit is using WebAssembly: https://medium.com/disney-streaming/introducing-the-disney-application-development-kit-adk-ad85ca139073
  • A simplified version of Photoshop on the web was released: https://www.theverge.com/2021/10/26/22738125/adobe-photoshop-illustrator-web-announced
  • Microsoft’s Flight Simulator has a WebAssembly-based plugin system: https://docs.flightsimulator.com/html/Programming_Tools/WASM/WebAssembly.htm
