(30/30) Learn Blazor Together: .NET 6 <ErrorBoundary>
Yesterday we talked about unit testing, but sometimes due to time constraints, comprehensive testing is not possible.
(29/30)Learn Blazor Together: Blazor Unit Testing
The most boring part of developing a system is probably fixing bugs, especially errors like trying to access a null object (`Object reference not set to an instance of an object.`), which is the most common problem most people encounter when they first step into programming. To break free from the tedious bug-fixing process, this article introduces `unit testing`.
(28/30) Learning Blazor Together: Policy-based Authorization
It was mentioned earlier that `ASP.NET Core Identity` uses `Claim`-based authentication. In fact, `ASP.NET Core Identity` has different types of authorization methods, the simplest being `Login Authorization`, `Role Authorization`, and `Claim Authorization`. However, all of the above are implemented in one way: Policy-based Authorization.
(27/30) Learning Blazor Together: Adding User and Claim Functionality
As mentioned earlier, `ASP.NET Core Identity` is based on `Claim` authentication, and `Role` is a `Claim` with type `Role`
(26/30) Let's Learn Blazor Together: Assign Roles to Users
Yesterday, the `CRUD` functions for roles were completed. Next, we need to assign roles to users.
(25/30) Let's Learn Blazor Together: Add Role Functionality
First, add a `ViewModel` to carry role data, because the upcoming permissions will be judged based on roles.
(24/30) Let's Learn Blazor Together: Using <AuthorizeRouteView>
The day before yesterday, we added content in `Blog.razor` to display both authorized and unauthorized views. However, if the unauthorized content to be displayed is the same across the system, writing it in every component would be a waste of time. We can use `App.razor` to handle unified presentation.
(23/30) Let's Learn Blazor Together: ASP.NET Core Identity (3)
Earlier, we mentioned `UserAuthentication()` and `UserAuthorization()`. The difference is that the former is used to verify who the user is, and the latter determines what the user can do.

Yesterday's authentication only targeted the Identity system and did not include our logs.
(21/30) Let's Learn Blazor Together: ASP.NET Core Identity (1)
Today, we'll implement the authentication part.
