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

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

I'm creating some samples for a project, and when using Console.WriteLine inside Tasks, the messages usually won't appear in the log window.

I'm currently required to add a "Thread.Sleep(1000)" or "Task.Delay(1000)" to allow the console buffer to appear.

It would be much better for everyone if this was handled by .NET Fiddle by default.

Now that Blazor server-side has been released and client-side in preview (due to be released with .Net 5 in November), you should think about supporting the project type on .Net Fiddle

On .NET Core, you cannot do Console.ReadLine() as it doesn't work on that platform for some reason

Please add this, at least as an option. Otherwise we can lose work. Thank you!

Was just trying to run through the c# tutorial and realised the fiddler doesn't allow you to run code with Console.Read etc. Would be a nifty feature :)

Hi it would be extremely useful if we had the Elvis operator.

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?

Such as 'Def.1.1.1', which I successfully referenced but could not use.

The error is:

Compilation error (line 13, col 21): The name 'Def' does not exist in the current context.

The site shows that the package is "on disk", but '/usr/nugetCache/def' does not contain 1.1.1.

Is there a problem?

Change the text color with Console.ForegroundColor

That the code can be used:
Console.ForegroundColor = ConsoleColor.DarkBlue;

Console.Write ("Hello");

Console.ForegroundColor = ConsoleColor.DarkRed;

Console.WriteLine ("World");

On top of each fiddle, it says "by <author's user name>". The author's username should be a link to take the user to all his/her fiddles.

It would be nice to see form submits pass through a controller method to another view. Currently I'm just throwing an exception to see passed values (https://dotnetfiddle.net/jZQKsM).

Any plans to support an Azure Function like interface with files area for run.csx, function.json?

Lots of C# developers out there who can't afford to have an Azure Tenant that can help collaborate on our projects.

As far my experience goes using dotnetfiddle.net, the "Tidy Up" functionality only remove unnecessary lines reducing code readability

It would come in handy to be able to click either the .NET Fiddle title in the top left corner, or a New Fiddle button to start over. Now, you have to refresh the page or go back to http://dotnetfiddle.net to create a new fiddle.

Support MyGet as a source for nuget packages, example:
// @myget: mypackage -Version 2.7.0

If you are typing in fiddle, and then realized you hadn't logged in yet, and then log in..POOF there goes all the work you've been entering for the past however long. Can you fix this somehow?
