What are the challenges of implementing Entity Framework in a distributed multi-layered architecture?

Implementing Entity Framework in a distributed multi-layered architecture presents several challenges. One such challenge is the performance overhead caused by lazy loading, where related data is fetched from the database only when accessed, potentially leading to additional database calls and increased response times. Another challenge is managing complex object graphs, especially in scenarios involving multiple layers of abstraction and relationships between entities. Additionally, Entity Framework may have limited support for executing stored procedures, which can be crucial in certain distributed architectures. Finally, handling disconnected scenarios, such as managing entity state across different layers and ensuring data consistency, adds complexity to the implementation.
