Blazor

Build interactive web UIs with C# instead of JavaScript using the .NET ecosystem.

Blazor enables full-stack development by executing C# directly in the browser via WebAssembly or on the server through SignalR. Developers leverage existing NuGet packages and shared class libraries to unify client and server logic (reducing code duplication). It integrates seamlessly with Visual Studio and supports modern features like hot reload, reusable Razor components, and direct DOM manipulation without the JavaScript overhead.
