Class PrefabLinkAttribute

Namespace
Bannerlord.UIExtenderEx.Attributes
Assembly
Bannerlord.UIExtenderEx.dll

Links a prefab patch or standalone mod prefab to its bound ViewModel type and, optionally, to the specific mixin type whose members it binds.

Consumed by Bannerlord.UIExtenderEx.Analyzers at build time to perform compile-time type checking, data-binding validation, and diagnostics across XML prefabs, ViewModels, and mixins. Ignored by UIExtenderEx at runtime.

For prefab patches, ViewModel corresponds to the active data source scope at the target injection node. For standalone prefabs, it corresponds to the root data source scope. If specified, Mixin must target the host ViewModel type or a base type when handleDerived: true is configured.
