Actualizado:junio 22, 2025

As a .NET Core domain developer, having a reliable online playground site or .NET sandbox website to test and experiment with programs is crucial. That's where .NET Fiddle comes into play. It is an online .NET sandbox/playground allowing programmers to write, compile, share fiddles through Twitter, log notifications, tag, collaborate, and execute in the browser before writing the final program in Microsoft Visual Studio.

The most sophisticated online compiler is Fiddle. You can use it to produce your school homework, ask or answer questions on Stack Overflow, embed examples on your blog, or even develop it using multiple project types like Console or MVC.
