.NET Fiddle Ideas

I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. List ALL My Fiddles on one page, or at least allow to set page size

    Why is the list limited to 10 fiddles? We should be able to see all of them, or at least have a page size option.

  2. Use monaco-editor as default editor

    Monaco-editor is MIT licensed and made by Microsft.
    It's the same text editor used in VSCode, and it is open source!
    It also has many interesting features like code diff and editor customization.

    See more here:
    https://github.com/Microsoft/monaco-editor

  4. 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!

  5. Expression Bodied Properties

    The following paste is an example of code that compiles in visual studio that does not appear to be supported by dotnetfiddle: https://dotnetfiddle.net/224Hvk

    I was just making a quick draft to make sure I understood the way this kind of assignment behaved to find it wouldn't compile on dotnetfiddle

  6. 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

  10. Ability to use PluralizationServices

    I get an error when I try to add a reference to System.Data.Entity.Design.PluralizationServices.

  15. Allow private main

    The .net compiler for real stuff doesn’t require the class `Main()` is in to be public nor `Main()` itself to be public. In fact, there’s no reason to write any access specifier in code since it doesn’t need to be public and is just extra noise, so I normally don’t in my one-off programs. Even [the VS templates for simple console apps](https://gist.github.com/binki/1f8ed17ed87cf4e78d3771d6f77cd0f9) uses `private` (by allowing the default access by omitting the keyword).

    Because .net fiddle doesn’t support this, it is impossible to copy/paste simple programs from VS into it to share with others with all the output,…

  17. C# 7.0 support

    Roslyn 2.0 is currently in pre-release state. As we get close to RTM, dotnetFiddle will be quite useful to try or demo C# 7 features.

  19. Public API for widget

    I would like to embed the Widget on my and to preform functions on it such as load a snippet to the editor or append and remove lines.
    This would allow me to create tutorials like tryfsharp.org

  20. Indentation problem with anonymous function

    See this example: https://dotnetfiddle.net/nGSHTF

    Typing return at the end of line 7 creates a new line with the wrong indentation. Adding spaces around the equals sign on line 8 causes the line to jump to the wrong indentation level.

    This seems to be related to the code on line 7 which splits a string into an array of integers.
