.NET Core Microservices - Implement Order Repository

This video tutorial explains how to access a database using DB context in .NET Core. It covers setting up a private readonly DB context, using dependency injection, and implementing async operations. The tutorial also discusses error handling and updating order status. The video concludes with a brief overview of the methods implemented and introduces the next topic of retrieving messages from Azure service bus.

What is the purpose of using dependency injection when accessing the database in .NET Core?

• To create multiple instances of the DB context

• To retrieve the DB context without creating a new object

• To avoid using async operations

• To directly access the database without a context

Which statement is used to efficiently manage resources when creating a new application DB context?

• async statement

• try-catch block

• using statement

• await statement

What is the role of the async keyword in database operations?

• To create a new DB context

• To perform operations without blocking

• To make operations synchronous

• To handle exceptions

How do you ensure that the order header is valid before updating the payment status?

• By verifying the order header is not null

• By ensuring the order header is empty

• By checking if the order header ID is zero

• By confirming the payment status is false

What should be done if an error occurs during the database operation?

• Retry the operation

• Return true

• Return false

• Ignore the error
