8. OpenID Connect and OAuth OpenID Connect (OIDC) is a simple identity and authentication protocol layer built on top of the OAuth protocol that allows applications (typically referred to as clients) to verify the identity of end-users. OAuth is an open standard for authorization that provides secure, delegated access, meaning that an application (or client) can take actions or access resources on a resource server on behalf of a user, without the user ever sharing their credentials with the application - the key being delegated access. Here's a diagram showing how these concepts and protocols fit together in a basic authentication and authorization scenario.

OIDC/OAuth flow. To summarize this workflow: The user (resource owner) initiates an authentication request with the authorization server. If the credentials are valid and everything checks out the authorization server obtains end-user consent and grants the client application an access token. The access token is attached to subsequent requests made to the protected resource server. The authorization server validates the access token; if successful the request for protected resources is granted, and a response sent back to the client application. Ok, we've covered off some theory behind identity, access control, OpenID Connect, and OAuth. Now we'll look at implementing a similar workflow using Angular, ASP.NET Core and IdentityServer4. Task Tread and Async 1. Tread life Cycle

How does the Task.WhenAll method work when handling multiple async tasks, and what potential issues could arise from its usage in C#? Answer Task.WhenAll is a method provided by the Task class that takes an IEnumerable or a set of Task instances as parameters and returns a new Task that completes once all input tasks have completed. Uses: It’s useful when you need to perform multiple asynchronous operations concurrently and wait for all of them to complete. It works by internally creating a new task that handles each child task’s completion and signals when all child tasks have finished. Potential issues: Exception Handling: When using Task.WhenAll, exceptions thrown by individual tasks are wrapped in an AggregateException. It’s crucial to handle this AggregateException and to unwrap it to understand the actual exceptions that occurred in the tasks. Otherwise, you may miss critical exceptions or experience unexpected behavior.
