+
+### Improved Type Resolution for `FrameworkEventInitType`
+
+The `FrameworkEventInitType` type has been enhanced to better resolve types for both `IFrameworkEvent` and `FrameworkEvent`.
+
+When defining events `FrameworkEventMap`, the dispatch type can now be inferred from the event type.
+
+#### Changes
+
+The type definition for `FrameworkEventInitType` has been updated as follows:
+
+```typescript
+export type FrameworkEventInitType<T> =
+    T extends IFrameworkEvent<infer U> ? U : T extends FrameworkEvent<infer U> ? U : never;
+```
+
+This change ensures that `FrameworkEventInitType` can now correctly infer the type for both `IFrameworkEvent` and `FrameworkEvent`.
