In `hooks.ts`: - Removed `interfaces` namespace usage - Updated `useNamedInjection` and `useTaggedInjection` to use the new v7 API with `GetOptions` - Fixed type issues with container methods 2. In `provider.tsx`: - Removed `interfaces` namespace usage - Updated container hierarchy handling to use the new v7 API - Implemented a new way to copy bindings between containers since direct access to bindings is no longer available - Added proper type checking for constructor functions using `Newable` 3. In `resolve.ts`: - Removed `interfaces` namespace usage - Updated type references to use direct imports The migration is now complete, and your project is fully compatible with Inversify v7. The key changes reflect Inversify v7's new approach to: - Direct imports instead of the `interfaces` namespace - Container hierarchy management - Binding access and manipulation - Named and tagged bindings -
