Just released a new version of PrettyLogging:

Supports line breaks in one line mode. Better or worse? :-)

In ASP.NET Core Identity, the `AddDefaultIdentity<TUser>` looks ... suspecious because it calls `AddAuthentication()` for us.

Well, it gets the service of IAuthenticationService from the IoC container. That means, some code is registering IAuthenticationService, and what is that? 🤔

It calls GetAuthenticationService and then calls SignInAsync on that. Right, what does GetAuthenticationService mean?

Digging a bit, there's actually an extension method described here: learn.microsoft.com/en-us/dotnet.... Good, what does that actually do?

#30MinsLearning Day 12, in the code implementation, this Context.SignInAsync() method got me confused for quite a while. Firstly, there's no SignInAsync() method on HttpContext class: learn.microsoft.com/en-us/dotnet... ...

#30MinsLearning Day 11, today, I read the code and created a top level sequential for `/login` of #aspnetcore #identity. The code is pretty straightforward. It supports 2 types of scheme - cookie or token. It starts with user name, password sign in, and check to see if 2FA is needed. For 2FA... 🧵

5 static results: Success, Failed, LockedOut, NotAllowed, TwoFactorRequired. And for each result, here's the status break down. Each row shows, for a given result, what's the status of the properties. For example, when the result is Success, only Succeeded property is true.

#30MinsLearning Day 10, move on to read '/login' in #aspnetcore #identity, keys about handling the SignInResult. And here's a break down of it. The class is pretty straight forward 🧵👇 #dotnet #csharp There are 4 boolean properties: Succeeded, IsLockedOut, IsNotAllowed, RequestTwoFactor. And 5 ...

#30MinsLearning Day 9, Ok, this 1 took 30+ mins. Well, to understand the code for `/register` of #aspnetcore #identity, I created a sequential chart to visualize it:
It takes 7 parties to finish the registration. It is #SOLID, but is it #overengineered? What about KISS? Worth it? 🤔 #dotnet #csharp

#30MinsLearning Day 8: Today, I read the code of UserManager.CreateAsync(), it relies on the PasswordStore to set the password hash, then calls the UserStore to create the user in real - like in db. The responsibilities are quite clear. >>>🧵 #dotnet #csharp #aspnetcore #identity #auth #authZ

Interestingly, it actually doesn't do too much but put the username onto the user object in UserStoreBase.cs. Looks like totally an overkill except its a virtual method. Hmm, needs more time to understand the reason. Probably needs to see the code in the user manager as well.

#30MinsLearning Day 5: I got the identityDB context into a #sql server. It is a journey. To reach here, I ran a sql express in #container on #Ubuntu, get basics of #EntityFramework migrations, figured out the nugets to reference, and derived IdentityDbContext. 💪 #dotnet
