Azure Devops build error

Current behavior

Hi guys, since today i get a very annoying build exception on Azure Devops pipeline.

##[error]CSC(0,0): Error CS1705: Assembly 'Uno.UI' with identity 'Uno.UI, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null' uses 'Microsoft.MacCatalyst, Version=17.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065' which has a higher version than referenced assembly 'Microsoft.MacCatalyst' with identity 'Microsoft.MacCatalyst, Version=16.4.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065'

The strange thing that i have no references to Uno.UI which boggles me. Local build works fine, but somehow, something is referencing this package.
These are the packages i have in my package references:

Thanks for the question.

This generally means that you azure devops agent has a version of the .NET workloads that is too old for the version of Uno that you're using. The best way to handle this is to use uno check to install the latest workloads to setup your build agent.

Executing something like this will be enough, on a windows machine, should get you running:

dotnet tool install --global Uno.Check --version 1.20.0
uno-check -v --ci --non-interactive --fix --skip gtk3 --skip vswin --skip androidemulator --skip androidsdk
