Architecture overview

Repositories

Repository	Purpose
Prism.SourceGenerators	Source generators, MvvmAIO.Prism.Core attributes, packaging, tests, CI.
Prism.SourceGenerators.Docs	This static documentation site (VitePress).
Prism.SourceGenerators.Samples	Avalonia sample apps (Prism 8 / 9).

Layout in Prism.SourceGenerators

Prism.SourceGenerators/           # Shared implementation (.shproj / .projitems)
Prism.SourceGenerators.Core/    # Attributes shipped as MvvmAIO.Prism.Core (referenced by apps + analyzers)
Prism.SourceGenerators.Roslyn*/ # Compiler-version-specific generator projects (NuGet compatibility)
Prism.Bcl.Commands/             # Optional Prism 8 AsyncDelegateCommand compatibility package

The shared project holds most generator logic. Roslyn* projects reference the Roslyn API version that matches each published package; the build selects the appropriate target so consumers get a generator compiled against their toolchain.

Major generators (conceptual)

Area	Responsibility
Observable / commands	[ObservableProperty], [DelegateCommand], [AsyncDelegateCommand], related attributes.
Container	Registration attributes → PrismRegistrationExtensions.g.cs → IContainerRegistry calls.
BindableBase	[BindableBase] INPC emission for types not inheriting Prism BindableBase.

Each pipeline uses Roslyn incremental generation (IIncrementalGenerator) with narrow attribute providers where possible so recompilation stays cheap.
