This post shows you how to check which versions of the .NET runtime and SDK are installed on your computer. If you have an integrated development environment, such as Visual Studio or Visual Studio for Mac, .NET may have already been installed.
Installing an SDK installs the corresponding runtime.
If any command in this article fails, you don't have the runtime or SDK installed.
Check SDK versions
You can see which versions of the .NET SDK are currently installed with a terminal. Open a terminal and run the following command.
.NET CLICopy
dotnet --list-sdks
You get output similar to the following.
2.1.500 [C:\program files\dotnet\sdk]
2.1.502 [C:\program files\dotnet\sdk]
2.1.504 [C:\program files\dotnet\sdk]
2.1.600 [C:\program files\dotnet\sdk]
2.1.602 [C:\program files\dotnet\sdk]
3.1.100 [C:\program files\dotnet\sdk]
5.0.100 [C:\program files\dotnet\sdk]
6.0.100 [C:\program files\dotnet\sdk]
Check runtime versions
You can see which versions of the .NET runtime are currently installed with the following command.
dotnet --list-runtimes
You get output similar to the following.

Check for install folders
It's possible that .NET is installed but not added to the PATH variable for your operating system or user profile. In this case, the commands from the previous sections may not work. As an alternative, you can check that the .NET install folders exist.
When you install .NET from an installer or script, it's installed to a standard folder. Much of the time the installer or script you're using to install .NET gives you an option to install to a different folder. If you choose to install to a different folder, adjust the start of the folder path.
