Where is .NET Core installed on macOS?

And exactly what versions are installed?

In a recent blog post Iris Classon wrote a PowerShell script that lists installed .NET Core SDK, runtime, and Framework Host versions installed on a Windows machine.

I am mostly using my Mac for .NET Core development so it got me thinking about where .NET Core actually is installed on macOS. The answer is

/usr/local/share/dotnet/

The following script

#!/bin/sh
DOTNET="/usr/local/share/dotnet"

if [ -d $DOTNET ] ; then

  printf "\nSDK versions:\n"
  ls -1 $DOTNET/sdk

  printf "\nInstalled runtime versions:\n"
  ls -1 $DOTNET/shared/Microsoft.NETCore.App

  printf "\nFramework host versions:\n"
  ls -1 $DOTNET/host/fxr
fi

will list installed .NET Core SDK, runtime, and Framework Host versions installed on a Mac.

If you run dotnet --info from the commandline you will see the default SDK version. You can change what SDK version to use by adding a section in the global.json file. The dotnet executable will look for such a file in the root folder of your project.

The format of the global.json looks like

{
  "sdk": {
    "version": "1.0.4"
  }
}

If you now run dotnet --info you should see:

tmp ➜ dotnet --info
.NET Command Line Tools (1.0.4)

Product Information:
 Version:            1.0.4
