installing on macOS

[greggjaskiewicz]

Hi there,

First of all, apologies if this is a bit of an off question.
We are looking to start using Maui for upcoming project, with 2-3 year release timeline.
I am completely new to Xamarin etc
I have installed Visual Studio on my mac.

However, after checking out the code and trying to run ./build.sh - I get this error.
I have tried installing the newer version of dotNet SDK, but it does not seem to be able to pick it up. I don't see any flags or such that I could pass into the build script to let it know where to find it.

Are there any instructions out there that would allow me to get from 0 to getting this installed please?

Hi, MAUI is a project in development by Microsoft with a release date of November 2021. If you are starting a project now just use Xamarin.Forms now and you can upgrade to MAUI when it’s released. MAUI is the successor to Xamarin.Forms so there will be a upgrade tool to convert your project from one to the other when it is released.
