What is the Unit of Work pattern in ASP.NET?

The Unit of Work pattern is a design pattern that helps manage database transactions in ASP.NET applications. It allows you to group multiple operations into a single transaction, ensuring that all operations either succeed or fail together.

How does it improve performance?

It improves performance by reducing the number of database calls. Instead of making a call for each operation, it batches them together, which minimizes the overhead and improves efficiency.

Can you give me an example of how to implement it?

Sure! You can create a UnitOfWork class that implements an interface, managing repositories and saving changes. For example, you might have methods like Commit() to save changes and Rollback() to undo them.

What are the common pitfalls to avoid?

Common pitfalls include not properly managing the lifecycle of the Unit of Work, leading to memory leaks, and failing to handle exceptions correctly, which can leave the database in an inconsistent state.
