The Complete Guide to ASP.NET Core MVC (.NET 5) - DbInitializer - Deployment Setup

The video tutorial explains how to deploy an application to Azure, focusing on automating database initialization and role creation using a DB initializer class. It covers setting up dependency injection, implementing the initialize method to handle pending migrations, and creating users with specific roles. The tutorial concludes with testing the setup to ensure everything works as expected.

• It holds the user's email confirmation status

What is the final step to ensure the DB initializer runs during application startup?
