 ## AOT-Compatible Property Attributes
 
 Supported attributes for properties in AOT mode:
-- **Argument** - Compile-time constant values
-- **MethodDataSource** - Static method data sources
-- **ClassDataSource** - Static class-based data sources
+- **MethodDataSource** - Data sources via calling a method
+- **ClassDataSource<T>** - A data source that injects in T
 - **DataSourceGeneratorAttribute** - Source-generated data (first item only)
-- **ClassDataSource** - Dependency injection with service provider
+
+For dependency injection with service providers, inherit from `DependencyInjectionDataSourceAttribute<TScope>` to create custom attributes. See [Dependency Injection](./dependency-injection.md) documentation for details.
 
 The AOT system generates strongly-typed property setters at compile time, eliminating reflection overhead and ensuring Native AOT compatibility.
