Is there an equivallent to a jsFiddle for ASP.NET / VB?

Is there anything out there that can do what jsFiddle does, but for asp.net things, like code I have in Visual Studio (vb)? Something where you can plug in your code, see the result, and perhaps save it so another coder can look at it and debug it? Thanks!

What will replace VB Net?

NET Core or, soon, to . NET 5.0, which will replace both the traditional . NET and the open-source and cross-platform . NET Core when it's released in late 2020.

.NET Fiddle supports ASP.NET MVC(thanks, @Eric) with both C# and VB.NET. Also there are several that either for ASP.NET(but C#) or VB.NET(but console or WinForms):

.NET Fiddle - supports VB.NET (ASP.NET MVC and console)
CodeRun Studio - supports ASP.NET but with C#.
Compilr - supports VB.NET (but only for console or Winform apps)
ideone - online compiler and debugger; supports VB.NET (but don't think you'll be able to run ASP.NET there)
