Hi,

Unfoirtunately, I do not have access to a Mac environment to test this on.

Going by the error message, it goes wrong in ListComponentBase. That is being used by the on the home page. I don't have a clue as to why that exactly is using reflection. Maybe you can do some testing with disabling Trimming?

Hello,

I've tried setting the <MtouchLink>None</MtouchLink> property in the project file but when I launch the app it crashes.

<Mtouchlink> is not something from us. Can;t help you with that.

What I meant is add something like this to the project file:

<ItemGroup>
 <TrimmerRootAssembly Include="Microsoft.FluentUI.AspNetCore.Components" /> 
</ItemGroup>

See also #1057. As this is not downloading assemblies like a regular WebAssembly app, you might consider to turn trimming of completely.

This has worked. Thanks, Vincent!
