OpenIddict configuration - asp.net-core

I'm in need of a detailed explanation on how I should configure OpenIddict in ASP.NET Core 7.
I have been looking at the available examples and documentation for a week now.
But I do not understand why some examples have ~400 lines of code and others have ~40, in their controller or endpoint implementations.
To make my use case and problem more specific:
Server side:
ASP.NET Core 7
Using minimal APIs
EF Core 7
PostgreSQL
Clients:
Blazor WASM or Angular
Decision not yet made
A skeleton Blazor WASM app created
Mobile apps (native iOS and Android)
I also need to refresh the token, and the user to access and modify the profile data.
I will also need to use other authentication providers (e.g.: Apple, Google).
I read the official docs and tried to undertand the examples.
Edit: I tried the Balosar and Zirku examples.
It left me more confused.
So my goal would be to understand why I need to add and how to configure certain services to achive the functionality described above.
Also, how to implement the needed endpoints, can I do it in minimal APIs, or do I have to stick with the controllers, or add views?

How can we implement Single sign on using C# WEB API (Without MVC)?

The idea is to implement Single-sign on using the given technical stack (ASP.NET CORE WEB API, IdentityServer4, ReactJS - Front end)
ASP.NET Core Identity together with IdentityServer4 offers an extensions for Single-Sign-On (Google, Microsoft ect.) for MVC framework. However, a proper guidance is not given for a WEB API scenario.
Please provide me an example or a tutorial, which I can follow in this regard?
Thanks in advance.
*** Update ***
Would be great if an example is given for the flow of events on this scenario, as to how should the communication happen between the Front end application and the backend.

Integrate ASP.NET Core Identity With Microsoft.Identity.Web in Blazor for Authentication

I have been working on authentication methods for my blazor app for some time now. I am currently developing as a standalone protected WebApi + Blazor Server, but will ultimately migrate to standalone protected WebApi + Hosted Blazor WASM so I need to be mindful of both server and client side authentication. The WebAPI will also serve an external OData feed and API for end users that also needs to be protected using the central authentication mechanism.
I would like to be able to sign on with Microsoft (ie. Microsoft.Identity.Web / MSAL), but want to configure some fairly complex roles and behaviours at the database level
(ie. ASP.NET Core Identity). To hopefully help someone else understand the different documentation sets, following are links to MS docs for the 2 options.
Introduction to Identity on ASP.NET Core
Microsoft Identity Platform Documentation
Don’t know about anyone else, but I have found it very difficult to navigate through the different documentation sets and tutorials to firstly understand how they work and secondly determine if it is best for me.
My question is, does anyone have any documentation on how they have integrated Microsoft.Identity.Web with the individual user accounts available in ASP.NET Core Identity for Blazor Server and/or WASM apps?, .
The following link shows how to do it all within ASP.NET Core Identity.
Integrate ASP.NET Core Identity with Microsoft account | BinaryIntellect Knowledge Base
If I was building an MVC web app, that’s what I would do. However, I really like the token handling capabilities of Microsoft.Identity.Web / MSAL (ie. ITokenAquisition etc.) for Blazor. It seems to be a real kludge to have to use the Razor pages for ASP.NET Core Identity and handling tokens securely becomes an issue – especially for Blazor WASM.
Chris Sainty has done some good work in porting some of the ASP.Net Razor pages to Blazor Components in the following link. However he does a lot of (very clever) manual processing of the token and I’m not sure I like the idea of storing the token in unprotected Local Storage of the blazor app. I haven’t gone into it in full detail yet, but I don’t think this method will be directly transferrable to Blazor WASM.

This SO post indicates that it is not possible to integrate Individual user accounts with Microsoft.Identity.Web.
c# - Microsoft Identity Plataform with asp.net Core Identity - Stack Overflow
I got a working solution going where I had both ASP.NET Core Identity and Microsoft.Identity.Web working side by side. However, I found this to be very difficult to implement and debug. Once you start mixing the various builder.Services.AddAuthetication(
) options (eg. .AddMicrosoftIdentityWebApp, . AddMicrosoftIdentityWebApi, .AddIdentityCore, .AddIdentity, .AddDefaultIdentity, .AddJWTBearer etc. etc.) I have found that you enter a world of pain and unpredictable behaviour. I basically had to go back to the source for each of them to work out what they were actually doing under the covers and work out how to blend them. I ended up going back to the raw OAuth / OpenId specifications and implementing everything manually – which is very unsatisfactory and I was unhappy with the risk I was taking in potentially introducing a security flaw – even though I got it to “work”.
EDIT: This SO post is similar to what I implemented. Microsoft Identity Local User Accounts and MSAL
I can’t believe how hard it has been to just get to this level of understanding, and still not have a solid working concept that does what I want it to do that is supported by documented acceptable techniques and not just my kludge at implementing everything manually.
Right now it appears to me that if I want to use as much out of the box / documented functionality as possible, I suspect that I should use ASP.NET Core Identity and work out how to integrate the ASP.net razor pages into my Web Api, Blazor Server and and Blazor WASM apps. However, this appears to be a backward step since Microsoft.Identity.Web / MSAL seems to be so much better suited to Blazor and seems to be the direction that MS is going.
If anyone can point me to some current examples of how this can be done, I would be very thankful.
I think I have found at least a partial answer to my question. The key problem I faced was how to capture the callback event from Microsoft.Identity.Web so that I can persist / retrieve info to/from the database during the authentication event. I was hung up on the ASP.NET Core Identity method of doing that.
I found the following SO post that provides information on how to respond to the OnTokenValidated event using Microsoft.Identity.Web. Microsoft.Identity.Web: OnTokenValidated event not triggered
Having access to this event means that I will be able to implement what I need to do at the database level and move on.

Getting an oauth token from AAD .net core app?

I will need to pass in an oauth token to a library in order to POST some information in a remote system.
For debugging purposes, I have created a basic app as per the Azure AD and OpenID Connect tutorial
At this point I am stumped. The documentation is somewhat opaque to a newbie and I have been unable to find relevant examples here and elsewhere.
Have a look at one of the samples here. You need to look for a Core app that calls another API (even Graph - it is also an API), e.g.: this one.

How can I have JWT authorisation in a standalone .NET Core ASP application?

I have been trying for weeks to implement JWT authorisation in my .NET Core web app and have found myself following a lot of guides that I don't think are relevant to my use case. These guides talk a lot about scopes etc, and I don't think I need that level of complexity for my use case.
A lot of the guides talk about using things like OpenIddict or Identity Server to setup and configure something that the user can authorise against, but in these settings it seems like a seperate project is required to house the identity provider, and then my new asp net core application has to somehow hook into that for use. I'm also trying to get things like refresh tokens to work so the user doesn't have to log in over and over again.
The "client side" of my app will be Xamarin (for mobile) and Angular (for web).
In a single web application (a single .net core application) how can I use .NET Core Identity with JWT or OAuth? What is the minimum level of configuration required to achieve this?

This is not asp.net core .This is just asp.net mvc project but this really simple and basic one. by watching this code, you will be clear how to implement JWT. Thanks

Basic Authentication with WCF Web API Preview 6

I'm trying to use the new WCF Web API Preview 6 with Basic Authentication. But don't really know where to begin.
zanewill apparently had the same issue:
https://stackoverflow.com/questions/8304367/how-to-use-basic-authentication-with-wcf-web-api
But the question is not a dup. I'm using this with mvc and don't really see how
Wcf Basic authentication
should apply?
I've tried out this:
http://cacheandquery.com/blog/2011/03/customizing-asp-net-mvc-basic-authentication/
But can't get it to work.
Should there not be an official solution from MS?
I have to note, that we are using our custom membership provider and that I basically just wanna pass an API token to the service. So the built in Windows Basic Authentification cannot be used.
I actually figured out a way myself. I've built my custom HttpOperationHandler and combined it with an Attribute, so I get a similar functionality as the MVC AuthorizeAttribute.
You can have a look at the solution here:
http://remy.supertext.ch/2012/02/basic-authentication-with-wcf-web-api-preview-6/
I think the recommended approach is to implement custom message handler. See my blog post for an example that works with ASP.NET Web API RTM:
