After marking the Dependency Injection library as deprecated, we should remove the old library code to clean up the repository and avoid confusion. The functionality has been moved to the Hosting package.

Tasks:

• Remove all source code from the Dependency Injection library
• Keep the library folder structure
• Add a README.md file in the library folder explaining:
  • The library has been deprecated
  • The functionality now lives in the Hosting package
  • Migration instructions or link to migration guide
  • Link to the new Hosting package location
