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. Use monaco-editor as default editor

      • 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

        • 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!

          • 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

                            • 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,…

                                      • 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.

                                        • Update the list of supported frameworks

                                          Given that MS have stopped supporting 4.5.1 and dotnet core has been released, it would be a good time to update the examples.

                                          I would love to use .NET Fiddle in the documentation pages for my OSS projects, but I can't install the packages (I think because of the Framework verisons)
