When you want to play with some code, but not in the middle of a big project, what do you do? For .NET developers, the answer is simple: You go to the .NET Fiddle sandbox and play around. The .NET Fiddle sandbox lets you create and edit code as you would on any other development environment, but with the added benefit of letting you share your code with the world. It’s perfect for learning new technology or experimenting with new ideas without the burden of committing to anything permanent. Plus, it’s completely free, and everyone can use it!
The Complete Guide
The .NET Fiddle sandbox is the perfect place to play with code and learn how to use the .NET platform. It’s free, easy to use, and you can run your code in any browser. Plus, there’s a great community of developers who can help you if you get stuck. If you’re just getting started, check out some tutorials here. Or jump right in by playing around with our sample fiddles.
You’ll find that coding for .NET doesn’t have to be complicated; it’s as simple as drag-and-drop! So what are you waiting for? Get started now. Play with our sample fiddles or try creating your own from scratch. You can create a new fiddle from one of the examples on this page, or select File > New from Scratch in the menu bar. Next, click inside the left hand panel (code window) to open up the code editor where you can enter commands and instructions that will appear on screen.
Just type text into this panel and hit Enter on your keyboard to see results or execute lines one at a time by selecting them with your mouse cursor before pressing Enter. Don’t worry about making mistakes; you’ll find everything is undoable if you make an error!
Start playing with .NET using Visual Studio Code
The .NET Fiddle sandbox is the perfect place to start playing with code. It’s a safe and secure environment where you can try out new ideas without affecting your live site. Plus, it’s easy to use and there’s no need to install anything. Simply create a new fiddle, select the desired programming language and start coding.
Your project will be saved as you go along so that even if you close your browser or hit an error, all of your work will be saved for when you want to come back later. You can also save as many copies of each project as needed.
Open a new fiddle by clicking New at the top right corner of this page. Write some code (or copy-paste from another website), and share it with friends or classmates by sending them the URL for your project. You can also ask for help on any existing projects by asking questions or commenting on other people’s work in their fiddles .
. Don’t forget to press Save Changes when you’re done making changes so that others can see your changes too. To edit other people’s fiddles, first comment on the code you want to change and then click Edit next to that comment. When you’re finished editing, click Save Changes again. All edits made to public content will be visible immediately.
Private content can only be seen by the person who created it and anyone they choose to share it with. If you have any problems, feel free to post your question on our forums and we’ll try our best to help!

Adding Functions, Arrays and Loops
Functions, arrays and loops are important concepts in programming. In the .NET Fiddle sandbox, you can experiment with these concepts without having to worry about setting up a development environment or compiling your code. Simply create a new fiddle, add some code and hit run. You can even share your fiddles with others so they can see what you’ve been working on. Light bulb! Create an array of numbers using new int).
Add one more number to the array, then use foreach loop to iterate over it and print out each value (e.g., Console.WriteLine(i) ). Change the last line of code to this instead: Console.WriteLine(End of Loop) ; Now when you hit Run button, it will end before going through all 10 values in the array because there is no End of Loop statement. That’s where foreach loop comes in handy as it automatically adds that statement for us when we use it!
