Build and Learn ASP.NET 6.0 Blazor Hands-On - Register the Data Access Services Class in Startup

The lecture explains how to register a data access service in the startup class using dependency injection. It covers the use of IServiceCollection and the AddTransient method, detailing the concept of service lifetimes. The video discusses the differences between Singleton, Scoped, and Transient lifetimes, and guides on choosing the appropriate one based on application needs.

What is the primary purpose of registering a data access service in the startup class?

• To initialize the database

• To set up middleware

• To enable dependency injection

• To configure routing

Which method is used to add a service with a transient lifetime?

• AddService

• AddTransient

• AddSingleton

• AddScoped

What does the transient lifetime imply for a service instance?

• A single instance is shared across all requests

• An instance is created once per request

• A new instance is created every time it is requested

• The instance is shared across multiple applications

Which service lifetime would you choose if you need a single instance shared across all HTTP requests?

• Singleton

• Session

• Scoped

• Transient

Why might you choose a transient lifetime for a service?

• To minimize memory usage

• To ensure a single instance is used across requests

• To allow instances to be shared between components

• To create a new instance for each request

What is a key advantage of using a transient service lifetime?

• It reduces the number of instances created

• It allows for parallel processing without shared state

• It ensures data consistency across requests

• It minimizes the need for garbage collection

In what scenario would you prefer a Singleton service over a Transient service?

• When each request needs a unique instance

• When the service is used infrequently

• When the service is lightweight and stateless

• When the service needs to maintain state across requests
