back to top  Dear KV,

I was recently hired as a mid-level Web developer working on version 2 of a highly successful but outdated Web application. It will be implemented with ASP.Net WebAPI. Our architect designed a layered architecture, roughly like Web Service > Data Service > Data Access. He noted that data service should be agnostic to Entity Framework ORM (object-relational mapping), and it should use unit-of-work and repository patterns. I guess my problem sort of started there.

Our lead developer has created a solution to implement the architecture, but the implementation does not apply the unit-of-work and repository patterns correctly. Worse, the code is really difficult to understand and it does not actually fit the architecture. So I see a lot of red flags coming up with this implementation. It took me almost an entire weekend to work through the code, and there are still gaps in my understanding.
