Why is a repository pattern important?
The Repository pattern makes it easy to test your application logic. The Repository pattern allows you to easily test your application with unit tests. Remember that unit tests only test your code, not the infrastructure, so repository abstractions make it easy to achieve that goal.

Is the unit of work necessary?
Not necessarily. EF already provides you with the unit of work pattern. The only reason to keep having a unit of work is if: you want to include non-EF data sources in an atomic data operation.
Do you need a repository pattern with EF core?
No, the repository/unit of work (abbreviated as Rep/UoW) pattern is not useful with EF Core. A better solution is to use EF Core directly, which allows you to use all the features of EF Core to produce high-performance database accesses.
What is the unit of work?
Maintains a list of objects affected by a business transaction and coordinates the writing of changes and the resolution of concurrency issues. A Unit of Work keeps track of everything you do during a business transaction that can affect the database. …
What is a unit of work pattern?
Unit of work is the concept related to the effective implementation of the repository pattern. non-generic repository pattern, generic repository pattern. The unit of work is referred to as a single transaction involving multiple insert/update/delete operations, etc.
Why shouldn’t I use the repository pattern with the Entity Framework?
Best reason not to use repository pattern with Entity Framework? Entity Framework already implements a repository pattern. DbContext is your UoW (Unit of Work) and each DbSet is the repository. Deploying another layer on top of this one is not only redundant, it also makes maintenance difficult.
How does the Rep/UOW pattern work in EF Core?
The Rep/UoW pattern does this by providing a method for adding or removing reviews from the book repository. Hide complex T-SQL commands – Sometimes you need to bypass the smarts of EF Core and use T-SQL instead. This type of access should be hidden from higher layers, but should be easy to find to help with maintenance or refactoring.
Why are repository and unit of work patterns important?
Implementing these patterns can help isolate your application from data store changes and can facilitate automated unit testing or test-driven development (TDD). In this tutorial, you will implement a repository class for each entity type.
Can you wrap a transaction in a repository pattern?
Yes, we can wrap all of that inside a transaction to make it even uglier! A pattern that goes hand in hand with the repository pattern is the unit of work. With the unit of work, we can rewrite that ugly code like this: now either both objects are saved together, or neither is saved. The database will always be in a consistent state.
