    C#, known as Csharp, is a general-purpose programming language designed by Anders Hejlsberg. It follows several programming paradigms . They are object-oriented, component-oriented, functional, declarative, imperative, and generic.

    Developers globally use the language for the development of

    • Mobile and desktop applications
    • Enterprise-grade software and applications
    • Websites and cloud-based services

    Are you interested in developing applications, websites, or games in C# ? If yes, using an integrated development environment and code editor will help you.

    This article introduces you to some best C# IDEs and code editors. Before that, let me help you know about a C# IDE and code editor.

    So, let us get started!

    What is a C# IDE?

    IDE is an acronym for an integrated development environment. It is a software offering several developer tools to ease the development process. It integrates all the tools required for writing and testing software under a single GUI. Standard tools include a source code editor, compiler or interpreter, and debugger.

    A C# IDE is a computer software offering various developer tools to speed up the development of Csharp applications. Or it is a single application enabling developers to create, run, and test C# applications.

    What is a C# Code Editor?

    It is a text editor enabling you to write and edit the source code of computer applications. A C# code editor enables the writing and editing of source code in Csharp.

    Writing and editing source code is the primary job of programmers and developers. Hence, code editors are the fundamental tools for them.

    They are part of all integrated development environments. Some standard features of code editors include:

    • Syntax highlighting
    • Auto code completion
    • Error detection
    • Brace matching functionality

    What is an Online C# IDE?

    It is also known as a cloud or web IDE. It is a browser-based integrated development environment. You write and edit the source code from your web browser.

    An online C# IDE allows writing and debugging Csharp code from within a web browser.

    You do not have to worry about installation with online integrated development environments. You can access them anywhere with an internet-enabled device. They let you develop apps even on low-powered machines.
