Should I use unit of work with EF core?
There’s no actual need to implement your own unit of work and repositories if they just wrap DbContext functionalities without adding any new value. Simple idea – use what you already have.
What is unit of work in EF core?
The unit of work class serves one purpose: to make sure that when you use multiple repositories, they share a single database context. That way, when a unit of work is complete you can call the SaveChanges method on that instance of the context and be assured that all related changes will be coordinated.
What is an EF unit?
The Engineering Fundamentals range is designed to enable students to gain an understanding of the fundamentals of engineering by the process of learning via hands-on experimentation.
Is DbContext a unit of work?
DbContext is a unit-of-work, and IDbSet is a repository; they are an abstraction; by wrapping it with your own, you’re making an abstraction over an abstraction, and you gain nothing but complexity.
Is Unit of Work necessary?
The only reason to still have a unit of work is if you: want to include non-EF-datasources in an atomic data operation. want to use a unit of work in your domain without relying on an EF dependency on that layer.
Should work units be transient or scoped?
Controllers should be transient though, only one is instantiated per request anyway 🙂 If you acquire the instance from the scope created for the request, they will be disposed of at the end of the request when the scope is disposed though.

Separation of Concerns: seperate application functionalities based on function, which facilitates evolving and maintaining the code.

How is the unit of work injected into the repository?
The Unit of Work is injected into the repository, as a mechanism to share whichever context it is working with. The job of actually calling the Commit method to save the changes to the database is the responsibility of the calling application and is not in the repository.
Can you use repository classes without a unit of work class?
You can use repository classes with or without a unit of work class. You can implement a single repository for all entity types, or one for each type. If you implement one for each type, you can use separate classes, a generic base class and derived classes, or an abstract base class and derived classes.
