Build and run Chefs.csproj for e.g. net10.0-desktop and Native AOT while using Uno 6.6.0-dev.3:

sed -i '' 's/"Uno.Sdk": ".*"/"Uno.Sdk": "6.6.0-dev.3"/g' global.json
git clean -xdf Chefs{,.Api}
dotnet publish -c Release -r osx-x64 -f net10.0-desktop -p:TargetFrameworkOverride=net10.0-desktop \
  -bl Chefs/Chefs.csproj -p:UseSkiaRendering=true -p:SkiaPublishAot=true \
  -p:IlcGenerateMapFile=true -p:IlcGenerateMstatFile=true -p:IlcGenerateDgmlFile=true -p:IlcGenerateMetadataLog=true \
  -p:EmitCompilerGeneratedFiles=true -p:CompilerGeneratedFilesOutputPath=`pwd`/_gen
Chefs/bin/Release/net10.0-desktop/osx-x64/publish/Chefs

From the launch screen:

1. Click Skip
2. Click  Sign in with Apple
3. Click ❤️Favorites in the left-hand pane
4. Click the My Cookbooks tab
5. Click the ➕Add floating-action-button (bottom-right)
6. Leave the Cookbook name field blank.
7. Click the Create cookbook button.

The problem is that the dialog which is shown is empty:

(no content here)
[Close]

The app log output contains:

fail: Uno.UI.DataBinding.BindingPropertyHelper[0]
      The [Title] property getter does not exist on type [Chefs.Business.Models.DialogInfo]
fail: Uno.UI.DataBinding.BindingPropertyHelper[0]
      The [Content] property getter does not exist on type [Chefs.Business.Models.DialogInfo]

As with commit 06f4f80, the problem is due to missing reflection metadata, and as with 06f4f80, there are "two" fixes, but really only one fix:

1. Add [Microsoft.UI.Xaml.Data.BindableAttribute] to the type indicated in the fail message: DialogInfo.

2. Add [System.Diagnostics.CodeAnalysis.DynamicDependency] to the constructor for all properties present in the type.

(1) is the easy solution, but as seen in 06f4f80, this causes build errors when targeting WinRT due to microsoft/microsoft-ui-xaml#8723.

Thus (2) is the only viable solution, tedious as it is.

With this fix in place the error dialog is now displayed as:

Error
Please write a cookbook name and select one recipe.
[Close]
