Let’s move on to the next sections to explore the benefits and drawbacks of using DotNetFiddle and learn about some alternatives that you can consider.

Benefits of Using DotNetFiddle

Using DotNetFiddle for coding in C# comes with several advantages. First and foremost, its online nature allows you to access it from anywhere, anytime, as long as you have an internet connection. This eliminates the need for a specific development environment on your local machine.

In addition, DotNetFiddle provides a platform for easily sharing code snippets with others. Whether you’re seeking feedback or collaborating with colleagues, you can quickly share your code by sending a link to your project. This makes it convenient for remote collaboration and efficient code review processes.

Another benefit of DotNetFiddle is its suitability for rapid prototyping and experimentation. With its intuitive interface and real-time compiler, you can quickly write and test code snippets without the need for setting up a full development environment. This makes it a valuable tool for quickly trying out ideas or experimenting with different approaches.

Drawbacks of Using DotNetFiddle

While DotNetFiddle offers many benefits, it’s important to consider its limitations and potential drawbacks. One of the primary limitations is its reliance on an internet connection. Since DotNetFiddle is an online platform, you need a stable internet connection to use it effectively. In scenarios where internet access is limited or unreliable, this could pose a challenge. If you’re using .NET Fiddle because you want to be on your phone or mobile device, this might be no issue at all if you’re still on the Internet.

Given that DotNetFiddle only allows you one editor window to work in for your C# code, if you try writing a complex application you’ll find it becomes cumbersome to use. Realistically, DotNetFiddle does not seem to be designed for this, so I feel like if you have realistic expectations about a freely available online C# compiler, you won’t actually have an issue.

Alternatives to DotNetFiddle
