How to install multiple versions of .NET on macOS

1. Add the Microsoft package feed to your system

brew tap isen-ng/dotnet-sdk-versions

2. Install the desired version of the .NET SDK

brew install --cask dotnet-sdk-6-0-400
brew install --cask dotnet-sdk-7-0-400

3. Verify the installation

dotnet --list-sdks

This way you can use multiple versions of the .NET SDK in parallel.

In your .NET code you can specify the desired version in the global.json file:

{
  "sdk": {
    "version": "7.0.400"
  }
}
