From @ReubenBond:

Currently, each project which needs a representation of an Order has its own representation. This makes refactoring complex and it leads to inconsistencies. Instead, we should have one or more shared projects which define the domain model.

If we see a benefit to having a mapped type in some cases (eg, types used in Blazor view models), we should do so, but we should simplify where we can.

From @SteveSandersonMS

I'm not sure how to repro this but have seen it twice now. You can have a state where the user is logged in and has a non-expired auth token, so WebApp shows you as being logged in, but:

• Calls to basketClient.GetBasketAsync succeed
• Calls to basketClient.UpdateBasketAsync fail, reporting RpcException: Status(StatusCode="Unauthenticated", Detail="The caller is not authenticated.")

You can get out of this state by logging out and then back in. But of course we don't want this to occur in the first place.

I suspect the issue is one of two things:

• Either the WebApp and BasketService disagree about the validity of the auth token, and GetBasketAsync simply doesn't enforce auth at all (perhaps it just returns an empty basket if the user isn't authenticated).
  • If this is the issue, maybe WebApp is incorrectly configured and isn't validating the auth tokens as strictly as it should be. No idea in what way the config might be wrong though - it was taken from the older MVC app.
• Or, BasketService is internally inconsistent about whether an auth token is valid

Here's what shows up to the user when trying to add an item to the cart in this state:

From @captainsafia:

Why can't these be records with primary constructors?

@davidfowl thinks they should be but we just need to test the entire flow.

Right now the .NET MAUI app only uses fake mock data. This needs to be updated to use the new endpoints.

Working with @michaelstonis

• Update design and any performance issues
• Update to latest .NET 8
• Use new endpoints
• Update Mobile BFF with any new apis needed
• Ability to run with or without auth

This isn't a bug (hopefully) but the checkout process currently deletes the basket twice. Once via the webapp and once via the basket API once the order process has started.

Clicking on the Northern Mountains logo from any page should take you back home. It currently doesn't do that at the login page.

@3lcarry

Would be interesting to see how much traffic we can handle with this architecture and where things start to break down.

Hi @davidfowl ,
I was walking through the Catalog.API code. In this file https://github.com/dotnet/eShop/blob/main/src/Catalog.API/Apis/CatalogApi.cs I see a usage of [AsParameters] CatalogServices services as a second parameter in all methods. I'm at loss to understand where CatalogServices is getting constructed. It is neither created in DI nor coming as a param. Can you please clarify?

We want to remove the scanning so we can potentially AOT more of eshop.

    "version": "8.0.100",
    "rollForward": "latestPatch",
    "allowPrerelease": false

From @captainsafia:

This app is currently an MVC app that we can rework to use Blazor Web.

• Make URLs lowercase
• Simplify some of the catalog URL patterns

From @bricelam

Today, database schema migrations are applied as certain components start up. This is problematic when multiple components (or multiple instances of the same component) use the same database.

Currently, for example, Ordering.BackgroundTasks immediately begins querying the OrderingDB database. This continually fails while waiting for Ordering.API to create and migrate the database schema to the latest version.

Data seeding (#10) should also be done at the same time.

We need to do an accessibility pass. @3lcarry will be handling this.

A couple of known issues:

• Missing tooltips when hovering over the user/cart icons.
• Footer text is blocked by banner image when looking at the identity page.

Currently, when opening the solution in Visual Studio, the "src" folder harbors an overwhelming number of projects.

I propose organizing it by grouping related modules into folders, as illustrated below.

I welcome comments from anyone with alternative suggestions on this matter.

• Basket.API
• Catalog.API
• ClientApp
• EventBus
• EventBusRabbitMQ
• HybridApp
• Identity.API
• IntegrationEventLogEF
• Ordering.API
• Ordering.BackgroundTasks
• Ordering.Domain
• Ordering.Infrastructure
• Payment.API
• Shared
• WebApp

From @danroth27:

We should pick a consistent name for the shopping cart/bag/basket.

Currently we have Basket.API, Cart.razor, and user facing text that says, "Your shopping bag".

From @SteveSandersonMS:

The user-facing text is all consistent on "shopping bag".

In the code, WebApp uses the term Cart, and the underlying service uses the term Basket. So those are indeed inconsistent, but in a way that is sort of valid - nothing strictly requires them to use the same term even though it would be better if they did.

Every online store I've used allows anonymously adding items to a shopping cart and then prompts for login during check out. Unusually, eshop requires logging in before adding items to the cart. I think the demo should follow the usual rules for websites.

Was this done for technical reasons? i.e. tracking cart items against an account, or to show off requiring auth in the cart APIs

Include what tech was used and that we're able to use it.

From @davidfowl

Clean up all of the extraneous content, the extra content globs etc.

Current implementation of eShop.Ordering.Infrastructure.MediatorExtension.DispatchDomainEventsAsync
will check tracked entities and publish all domain event those entices hold once, which triggers domain event handlers to handle published events.
However, in real world applications, domain event handlers might also cause new domain events generated, and in current implementation new created domain events will be ignored.

I wrote this implementation that will keep publishing created domain events from tracked entires recursively, utill there are no more left. Please consider.

static class MediatorExtension
{
    public static async Task DispatchDomainEventsAsync(this IMediator mediator, OrderingContext ctx)
    {
        bool remains = true;
        while(remains) {
            var publishedCount = await DispatchDomainEventsRecursivelyAsync(mediator, ctx);
            remains = publishedCount > 0;
        }
    }

    private static async Task<int> DispatchDomainEventsRecursivelyAsync(this IMediator mediator, OrderingContext ctx)
    {
        var domainEntities = ctx.ChangeTracker
            .Entries<Entity>()
            .Where(x => x.Entity.DomainEvents != null && x.Entity.DomainEvents.Any());

        var domainEvents = domainEntities
            .SelectMany(x => x.Entity.DomainEvents)
            .ToList();
        int count = domainEvents.Count;

        domainEntities.ToList()
            .ForEach(entity => entity.Entity.ClearDomainEvents());
        
        foreach (var domainEvent in domainEvents)
            await mediator.Publish(domainEvent);
        
        return count;
    }
}

Would be happy to create the PR.

From @danroth27

The web app is hosted on an HTTPS address, but it displays images that are retrieved over plain HTTP, which results in lots of "Mixed content" warnings in the browser dev console.

From @danroth27

The web app configures the exception handling middleware to route requests to /Error:

if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

But no /Error endpoint is defined in the app.

From @ReubenBond:

Currently, there are many integration events which have duplicated representations across projects, which makes the complex Order processing flow even more complex because developers cannot use tooling to find usages of the integration event types.

Instead, let's use one or more shared projects to describe these events so that FindAllReferences/etc work.

From @bricelam:

It is the professional opinion of the EF team that the DDD patterns employed in the Ordering.API and related projects are of no value (and possibly even result in negative value) and can safely be removed for the sake of maintainability.

This includes, but is not limited to:

• Removing the types under the src/Ordering.Domain/SeedWork/ directory
• Use actual CLR enums for CardType and OrderStatus
• Update OrderQueries to use EF LINQ queries
  • Make ViewModel classes more idiomatic
• Consider Using IdentityGuid as the primary key (instead of the current surrogate key) for Buyer
• Review the unusual use of transactions and the SaveChanges call in TransactionBehavior

There are lots of applications in there that no longer use auth or have been deleted.
