Hey Patrick, thanks for taking the time to make this awesome series, its one of the best I've found to date! The next sections can't come quick enough!

Any chance you could cover seeding data to a DB so that we can seed the setup data each time a new instance of the application is run? ie. the data like rpg classes which we wouldn't want to recreate each time, but rather just seed the standard 5 or 6 classes that one can choose?

Another idea might be to cover role based calls so that if I am an "admin" user, a call might return different/more data than if I was a "standard" user?

Thanks again and keep the content coming!

PS. In your video series maybe you could also include setup on a Mac? SQL is not available for Mac users so I wasn't able to easily connect to a local DB. It took a little research but I eventually got my SQL DB up and running on a docker image.

Hi,

Thank you very much! :)

These are good ideas. I will remember them and probably add them as "bonus" chapters - at least regarding seeding the database and role based authentication.

I'm afraid I don't have a Mac. But maybe I'll add a chapter with SQLite. You can use SQLite on MacOS, hence you wouldn't have to use SQL Server with Docker. The code should stay the same, just the connection string would be different, I guess.

Let me think about this. ;)

Take care,
Patrick

Hi Patrick,

This is a great series, thanks for the effort you are putting into this.

In this episode, CreateToken is first shown as being declared 'static' but I don't think it should be?

Many thanks!

Patrick God • Mar 25 '20

Hello again and thank you very much again. :)

And you are correct again, I removed the static keyword.

Stay healthy!
Patrick

This is the most lucid, clear explanation I could find of how to do this. I'm a long-time .NET developer, but sometimes walking into a new framework there's just so much any abstractions that it's hard to know where to start. Thank you!

Thank you very much, Nicholas! :)

I have learnt a ton from this series, thank you for selflessly sharing Patrick!

Would you mind showing us how we can go about resetting a users password? The username in my test application is a email address.

I have implemented the following mailkit solution and it works pretty well apart from minor bugs that was fixed in the version I am using - Version="2.10.1

When you used AddJwtBearer in Startup.cs, the AppSettings token was converted by the GetBytes method of Encoding.ASCII instead of Encoding.UTF8 like in AuthController. But then I tried running it and it still worked. Could you explain to me why?
