An integrated development environment (IDE) is an application that combines a range of tools for developing software, typically including a code editor, code completion, code analysis and diagnostics, running tests, and debugging. Unity supports the following C# IDEs:
The External Script Editor setting in the Preferences window determines which IDE Unity C# script files open in for editing. To change this setting, go to Unity > Preferences > External Tools > External Script Editor.
This setting is enough if all you want to do is open, view, or make simple edits to C# source files. A full IDE experience including code analysis and debugging typically requires additional plugins or extensions. Refer to the sections for each supported IDE below for more details.
