What is Blazor in .NET and how does it differ from ASP.NET?

Blazor is a web framework that allows you to build interactive web applications using C# and .NET instead of JavaScript. It is based on WebAssembly, a standard that enables running code written in multiple languages on web browsers at native speeds.

One of the key differences between Blazor and ASP.NET is the use of client-side versus server-side execution. In ASP.NET, web applications primarily run on the server and send HTML to the client, whereas with Blazor, the application's logic and rendering can happen on the client side using WebAssembly.

Additionally, Blazor provides a component-based architecture that promotes reusability and helps in creating dynamic and interactive user interfaces. This differs from the traditional ASP.NET approach, which relies more on server-side controls and postbacks for interaction.

Overall, Blazor offers a modern and efficient way to build web applications with .NET, leveraging the power of C# and the flexibility of WebAssembly for client-side execution.
