The development of web applications using Blazor technology brings numerous advantages and possibilities for developers. Blazor is a modern technology that allows the creation of interactive web applications using C# and the .NET platform. Instead of the traditional separation between client-side and server-side, Blazor enables developers to use the same language and environment for development and execution on both sides. One of the key benefits of Blazor is the ability to run code on the client side using WebAssembly (Wasm). This allows the execution of C# code in the web browser, resulting in faster and more interactive user interfaces. The client side of the application can be executed locally on the user's device, reducing the load on the server-side and improving performance. Blazor supports different development approaches, including Blazor WebAssembly and Blazor Server. Blazor WebAssembly enables full client-side execution of the application, while Blazor Server uses SignalR to maintain the connection between the client and the server. Both approaches have their advantages and can be adapted to specific project requirements. By using Blazor, developers can leverage the power of the C# language and the richness of the .NET ecosystem to create reactive user interfaces, handle events, perform data validation, and interact with backend services. Blazor also supports the use of existing .NET libraries, making it easy to reuse code and integrate with existing applications. The development of web applications using Blazor also brings simplicity to maintenance. Since the same language and environment are used on both sides, developers have a unified development experience and can share code, components, and logic between the client and the server. This results in less duplicated code, increased productivity, and easier maintenance of the application.
