Question 1

How do I perform CRUD operations with NPoco?

Accepted Answer

Use methods like db.Fetch for reading, db.Insert for creating, db.Update for updating, and db.Delete for deleting records. For example, db.Insert(new User { Email = 'test@example.com' }) adds a new user, with mapping handled automatically.

Question 2

Does NPoco support async database queries?

Accepted Answer

Yes, NPoco provides async versions of its methods, such as FetchAsync and ExecuteAsync, allowing non-blocking database calls in modern .NET applications for better scalability.

Question 3

How does NPoco handle complex joins or relationships between tables?

Accepted Answer

NPoco can map joined queries to POCOs by matching column names to properties, but for complex relationships like one-to-many, you may need to write custom SQL and handle mapping manually or use nested objects.

Question 4

NPoco vs Dapper: which micro-ORM is better for .NET?

Accepted Answer

NPoco offers more automatic POCO mapping out of the box with less configuration, while Dapper is more minimalistic and requires custom mapping for complex scenarios. Choose NPoco for simplicity in mapping, and Dapper for ultimate control and speed.

Question 5

Is NPoco compatible with .NET Core and .NET 5+?

Accepted Answer

Yes, NPoco targets .NET Standard and works seamlessly with .NET Core, .NET 5, and later versions, using standard database providers like SQL Server, MySQL, or PostgreSQL.

Question 6

How to manage transactions in NPoco?

Accepted Answer

Use db.BeginTransaction() or the TransactionScope for managing transactions. Wrap multiple operations in a transaction to ensure atomicity, with rollback handled automatically on failure.
