For my brilliant friend Steve.

AOT-Safe, Source-Generated, ViewLocation for Avalonia

===========================

1. Assembly-Setup 1.1) The Source-Gen assembly is netstandard2.0 and requires:

==========================

=========================

[ It's only v3.8.0 because Avalonia requires exactly that version. ]

1.2) Keep in mind there can be problems when trying to change the roslyn- assemblies' versions due to the Avaloniaan dependency.

++++++++++++++++++++++++++

2. Usage 2.1) Set the import-usings via the AddNamesspaceUsings()-method [marked A)] 2.2) Set the namespace-name via the field s_Setting_Namespace [markedB)] 2.3) In App.xaml.cs at invocationstart of OnFrameworkInitialized() init the ViewLocator and call the ViewLocator.PopulateViewModelViewMappings()-method [marked C)] 2.4) ViewLocator-class needs to be partial 2.5) In the class that references the SourceGen, modify the reference, adding OutputItemType="Analyzer" ReferenceOutputAssembly="false" to the end of the Project-Ref.

==========================

==========================

2.6) Make sure the ViewLocator.cs class provides the same functionality like (or is) the ViewLocator.cs in this project. It needs the Locator-Dictionary and has to use the factories.

3. Testing / Debugging I'd like to see what the Source-Gen generates...

   In the .csproj that references the Source-Generator add these settings to the main Propertygroup:

=========================

true $(ProjectDir)GeneratedFiles

=========================

In the Main-Solution-Directory will spawn a GeneratedFiles-dir which hosts the generated sources. In order to be able to run the project again, you will have to delete these files quite certainly. [since Avalonia's source-generated files will also spawn there, and create duplicate Type-Errors]
