+## InjectMembers: Attribute-Level Injection Without `[IocInject]`
+
+When you cannot add `[IocInject]` directly to a type's members (e.g., a third-party type), use the `InjectMembers` property on `[IocRegisterFor]` to specify injection points from the registration site:
+
+```csharp
+// Register ThirdPartyService without modifying it
+[IocRegisterFor(typeof(ThirdPartyService),
+    InjectMembers = [nameof(ThirdPartyService.Logger)])]
+public static class ThirdPartyModule { }
+```
+
+Each element is one of:
+
+| Format | Description |
+| :--- | :--- |
+| `nameof(T.Member)` | Inject without a key (resolves `T` from the container) |
+| `new object[] { nameof(T.Member), "key" }` | Inject a keyed service |
+| `new object[] { nameof(T.Member), nameof(SomeKey), KeyType.Csharp }` | Inject using a C# expression key |
+
+> [!NOTE]
+> When the same member is specified in both `InjectMembers` and via `[IocInject]` on the member itself, `[IocInject]` takes priority.

 When working with open generic services, you can use a **generic factory method** to create instances. This requires the `[IocGenericFactory]` attribute to map service type placeholders to factory method type parameters.

+## Generic Factory Without `[IocGenericFactory]`
+
+As an alternative to placing `[IocGenericFactory]` on the factory method, you can specify the type mapping directly on the registration attribute via `GenericFactoryTypeMapping`. This is useful when you cannot modify the factory method (e.g., a third-party library).
+
+```csharp
+// No [IocGenericFactory] attribute needed on the factory method
+[assembly: IocRegisterDefaults(
+    typeof(IRequestHandler<>),
+    ServiceLifetime.Singleton,
+    Factory = nameof(ExternalFactory.Create),
+    GenericFactoryTypeMapping = [typeof(IRequestHandler<Task<int>>), typeof(int)])]
+
+public static class ExternalFactory
+{
+    // Third-party or shared factory — cannot be modified
+    public static IRequestHandler<Task<T>> Create<T>() 
+        => throw new NotImplementedException();
+}
+```
+
+The `GenericFactoryTypeMapping` property uses the same format as `[IocGenericFactory]`:
+
+- **First element**: the service type template with concrete placeholder types (e.g., `typeof(IRequestHandler<Task<int>>)`)
+- **Remaining elements**: the placeholder types that map to factory method type parameters in order
+
+> [!NOTE]
+> `GenericFactoryTypeMapping` is available on `[IocRegisterDefaults]` and `[IocRegisterFor]`. When both `GenericFactoryTypeMapping` on the attribute and `[IocGenericFactory]` on the method are present, `[IocGenericFactory]` takes precedence.
