Add support for collapsible regions

Support for System.ServiceModel would be very helpful.

I get an error when I try to add a reference to System.Data.Entity.Design.PluralizationServices.
'The type of namespace name 'Design' does not exist in the namespace 'System.Data.Entity'

Please give us inverted color theme, most developers are working with "white on black"

We need the same quick keyboard shortcuts as visual studio...
CTRL+D - Duplicate line
CTRL+K+C - Comment out line
CTRL+K+U - Uncomment line
ALT+ENTER - Automatically add or suggest missing namespace reference and add usings to the class (like resharper)

TOTAL IDEA :
1 - Font Size Change
2 - Set Automatic Color Syntax According to Commands (Like Notepad++)
3 - Add C++, Python , JavaScript , ... and more
4 - disable problem always set "Autorun on"
5 - Security Type : Public , Links , Private , Passworded
6 - Graph Output like Draw line.....

allow us to

1) View the compiled razor
2) allow code folding of codetags and collapse/expand code for readability

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.

Allow for a teacher/student structure whereby a teacher can have access to students' files and create tutorials on .NET Academy visible to only students.

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

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.

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)

It would be cool to mark some words as `code` and others as *emphasized*.

Please create mobile app for this wonderful service. It may help lots of people where accessing laptops or systems is not easy.

Please create My Fiddles on the left hand side Option's window or on right hand side (New window) so that one can easily switch between files if required.

Sometimes it is nice and handy to write a stuff and download it not messing with csc

I have added Automapper v4.2.1 to create some snippets and getting the below error.
Run-time exception (line -1): Could not load type 'AutoMapper.MapperConfiguration' from assembly 'AutoMapper, Version=3.2.1.0, Culture=neutral, PublicKeyToken=be96cd2c38ef1005'.

It looks like that you need to add an assembly redirect field in config to map to take the version added.
