Start up the application and try to access the /ManageUsers route while
logged in as a normal user. You'll see this access denied page:
That's because users aren't assigned the Administrator role
automatically.
Create a test administrator account
For obvious security reasons, it isn't possible for anyone to register a
new administrator account themselves. In fact, the Administrator role
doesn't even exist in the database yet!
You can add the Administrator role plus a test administrator account to
the database the first time the application starts up. Adding first-time
data to the database is called initializing or seeding the database.
Create a new class in the root of the project called SeedData :
