.NET Fiddle Ideas

  1. Add System.Windows.Forms

    Some of my code uses System.Windows.Forms.BindingContext (i.e. non UI code) and I want to reference it dotnetfiddle.net

    Unfortunately I can't write `using System.Windows.Forms;` as I get the error Compilation error (line 2, col 22): The type or namespace name 'Forms' does not exist in the namespace 'System.Windows' (are you missing an assembly reference?)

  2. Solution/Project Explorer

    I would like to be able to create projects that contain multiple files so that I can create tutorials to teach student.
    The MVC project type for example allows for multiple files. but they are all together on screen and I can't close one down to focus on say the controller.

    VS Code uses Theia https://www.theia-ide.org/index.html - Perhaps you could also use this in your UI?

  3. Be able to include import a Github repository

    This would really help to make samples of bugs / issues in a repository. One could import all the files of a repository, then write a "Test" that fails and the owner of the repository could then check out why it fails easily.

    See for example me manually uploading the files in a competitors product:
    https://repl.it/@devedse/ErrorWhenLoadingJpgWithExif

  4. Bug(?)

    I was coding something and had some code to tell the user to press enter to continue. I did not want to keep writing it, so I copy and pasted it. However, this made my code go wonky. I had a switch later in the program and I was testing it out making sure it worked. I had copied and pasted the code after the switch, and this is where it gets weird... every time I ran it, it would go back to where I copied the code from and rerun the switch. I don't know why it happened but…

  7. 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"

    Why would you make a Nuget Header Directive available for C# but not for VB.Net?

  9. User main page

    It would be nice to have a user page that lists the Fiddles that we have created. A main page of sorts.

  10. Specify timezone for snippet

    Sometimes I need to check a code that works with local timezone which should be different from UTC. It would be great to have an ability to specify timezone in that cases. Thank you!

  16. Enable adding assemply attributes like assemplyinfo.cs

    some class libraries loaded from nuget need setting assembly attributes located in assemplyInfo.cs otherwise it fire an exception, like:

    [assembly: AssemblyCompany("Company xyz")]
    [assembly: AssemblyCopyright("Copyright © 2018 Company xyz")]

    Enable setting these attributes in assemplyInfo.cs

  17. 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!

  18. 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.

  19. Allow inclusion of other exiting fiddles

    For example: I define a class Person in a fiddle named PersonClass.
    Then I base a new fiddle PersonUseExample on existing fiddle PersonClass, so I don't need to declare the class again, just démonstrate how I can use it.

    The idea is probably easier to implementis but similar to the exiting request: https://dotnetfiddle.uservoice.com/forums/228764--net-fiddle-ideas/suggestions/6056568-allow-multiple-files-for-console-projects
