Unable to load shared library libgdiplus or one of its dependencies

Overview ☀

While testing a feature locally on my macmini I was uploading an image when I got the following error:

Unable to load shared library ‘libgdiplus’ or one of its dependencies

Dependencies 🌱

So, after a quick google the following was suggested to me:

mono-libgdiplus

brew install mono-libgdiplus

I already had this installed but I re-installed just in case

That did not work so the next option available was to add a reference to a NuGet package that allows you to use System.Drawing on macOS

runtime.osx.10.10-x64.CoreCompat.System.Drawing

<PackageReference Include="runtime.osx.10.10-x64.CoreCompat.System.Drawing" Version="5.8.64" />

And with that all was working again.

Success 🥳
