I wrote a simple C# file. When I compile it using command prompt, I get an error

'csc' is not recognized as an internal or external command, operable program or batch file.

Do I need to set an environment variable?

  • When you have a VS installed then there should be a "Visual Studio Command Prompt" too. It has those settings preconfigured. – H H Jul 11 '15 at 11:01

When you install Visual Studio it comes with it a batch file that sets up the environment for you and opens a cmd window. It's called Developer Command Prompt for VS201x (where x is the Visual Studio version you have). It is located in the Visual Studio Tools menu, usually at:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Visual Studio 201x\Visual Studio Tools

This is the result:

EDIT:

If you don't have Visual Studio installed you can still access the C# compiler shipped with the .NET Framework in Windows 8. You will find it in:

C:\Windows\Microsoft.NET\Framework\v4.0.30319

Otherwise you can install it manually. Here is the link

What you need to do after is just adding it to your environment variable path

Hope it helps.
