What are the main difficulties encountered when managing and maintaining an ASP.NET Core project implemented with a standard template?

When managing and maintaining an ASP.NET Core project implemented with the standard template, the following difficulties often arise:

• Scaling complexity: The standard template may not provide a clear architecture, making it difficult to add new features and support.
• Lack of clear layer structure: Mixing presentation logic, business logic, and data access complicates maintenance.
• Configuration and dependency issues: The standard template may not use Dependency Injection effectively, complicating testing and component replacement.
• Security problems: The template may not include advanced authentication and authorization mechanisms, requiring modifications.
• Limited customization: The template is oriented towards common scenarios, making it difficult to adapt to specific requirements.

To address these issues, it is recommended to apply architectural patterns (e.g., Clean Architecture), use Dependency Injection, implement modular testing, and carefully plan the project structure.
