How to check that .NET is already installed

Feedback

In this article

This article teaches 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, .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. For more information, see the install articles forWindows,macOS, orLinux.

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.

dotnet --list-sdks

You get output similar to the following.

7.0.404 [C:\program files\dotnet\sdk]8.0.100 [C:\program files\dotnet\sdk]9.0.306 [C:\program files\dotnet\sdk]10.0.100 [C:\program files\dotnet\sdk]
7.0.404 [/home/user/dotnet/sdk]8.0.100 [/home/user/dotnet/sdk]9.0.306 [/home/user/dotnet/sdk]10.0.100 [/home/user/dotnet/sdk]
7.0.404 [/usr/local/share/dotnet/sdk]8.0.100 [/usr/local/share/dotnet/sdk]9.0.306 [/usr/local/share/dotnet/sdk]10.0.100 [/usr/local/share/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 thePATH 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.

  • dotnet executable
    C:\program files\dotnet\dotnet.exe

  • .NET SDK
    C:\program files\dotnet\sdk\{version}\

  • .NET Runtime
    C:\program files\dotnet\shared\{runtime-type}\{version}\

  • dotnet executable
    /home/user/.dotnet/dotnet
    /usr/lib/dotnet/dotnet
    /usr/share/dotnet/dotnet\

  • .NET SDK
    /home/user/.dotnet/sdk/{version}/
    /usr/lib/dotnet/sdk/{version}/
    /usr/share/dotnet/sdk/{version}/\

  • .NET Runtime
    /home/user/.dotnet/shared/{runtime-type}/{version}/
    /usr/lib/dotnet/shared/{runtime-type}/{version}/
    /usr/share/dotnet/shared/{runtime-type}/{version}/\

  • dotnet executable
    /usr/local/share/dotnet/dotnet

  • .NET SDK
    /usr/local/share/dotnet/sdk/{version}/

  • .NET Runtime
    /usr/local/share/dotnet/shared/{runtime-type}/{version}/

More information

You can see both the SDK versions and runtime versions with the commanddotnet --info. You'll also get other environmental related information, such as the operating system version and runtime identifier (RID).
