  2. Remove redundant indentation at the second line of the C# template

    There exists five redundant horizontal tabs 0x09 at the second line of all C# templates (Framework, Core, and Roslyn). They have existed for at least a year now.
    I am hoping they can be removed.
    Thanks.

  4. Bring in proper C# 7 tuple deconstruction

    Simple test:

    static (int, int) Foo(int i)

    {
    
    return (i+2, 1*2);
    }

    Current "result" :
    Predefined type 'System.ValueTuple`2' is not defined or imported

    Expected:
    To compile (and work of course :-)

    This includes updating "4.7.2" "Compiler" to accept C# 7.x and at least linking the proper dll with ValueTuple-a for "Roslyn 2.0"

  5. Add new files to fiddle "project" expecially the global.asax.cs

    This is especially valuable with MVC fiddle type as one cannot add additional views or define their own routing.

  6. Debugging

    Allow the usage of debugging such as stepping into a function, out of a function, run, memory mapping, local variables and the whole nine yards. It is vital if you don't want users to write constantly Console.WriteLine() statements.

    Kindly, add debugging!

  8. Debug.Assert

    Support for System.Diagnostics.Debug.Assert could be added. Given that it's an internal verification system that fails when the assertion is incorrect, it could be helpful to at least throw a message in the output window when an assertion wasn't working

  9. Support ScriptCS

    ScriptCS has a syntax for loading assemblies and works better as a single file. I don't know if you plan on allowing .NET Fiddles (?...is that the plural of the thing you make in .NET Fiddle?) to load other assemblies, but I think it would be really cool to be able to do that.

  10. Support For Akka.NET

    Currently, dotNetFiddle throws when trying to use Akka.NET.
    There is an error message saying that some methods in JSON.NET are missing.
    We would love to have the ability to run live Akka samples from our docs site.

    ALT+ENTER - Automatically add or suggest missing namespace reference and add usings to the class (like resharper)

  12. Enable Vim key bindings.

    Please enable vim key bindings. VsVim is one of the most downloaded Visual Studio extension, which is an indication of Vim key binding's popularity among .net devs.

  15. Keep Nuget Packages

    When you add a nuget reference save it in the fiddle so when you open the fiddle again, either on the same machine or a different one, the packages are still there and you don't have to search for them again

  16. Support null check operators

    Allow the compilation of null check operators i.e. DataSet?.Tables.Count. Currently the "?" screws up everything and a compilation error is received:

    Code:
    System.Data.DataSet ds = null;

        if (ds?.Tables.Count == 0 || ds?.Tables[0]?.Rows.Count == 0)
    
    {
    Console.WriteLine("True");
    }
    else
    {
    Console.WriteLine("False");
    }

    Errors:
    Compilation error (line 8, col 10): Invalid expression term '.'
    Compilation error (line 8, col 11): Syntax error, ':' expected
    Compilation error (line 8, col 35): Invalid expression term '.'
    Compilation error (line 8, col 36): Syntax error, ':' expected
    Compilation error (line 8, col 46): Invalid expression term '.'
    Compilation error (line 8, col 47): Syntax error,…

  17. Allow console output and the code to viewed in separate tabs

    In CodePen, you can show the HTML, CSS, and JS on one half of the iframe and the result on the other half, as well as open and close them by clicking on tabs located at the top of the iframe. It would be awesome if we could have the code be on one tab, and the console output on the other tab

  18. work on projects as a whole and being able to download them after

    Allow you to work on whole projects instead of a single at a time. Having the tree listed on the side allowing you to jump from page to page and looking more like a whole project. Also being able to download your project when it's completed

  19. Update NuGet

    When trying to install System.Xml.XPath from NuGet (any version listed in the menu), installation is not allowed and this message is included at the end of the description of the package: "When using NuGet 3.x this package requires at least version 3.4". I think that updating NuGet is an important and urgent step for the functionality of this site. Gracias!
