[Bug] Cannot resolve scoped service when Debug via Visual Studio on Windows - Works using Linux Container

[Johno-ACSLive]

Which version of Microsoft Identity Abstractions for dotnet are you using?
Microsoft Identity Abstractions version 5.3.0 via Microsoft.Identity.Web.DownstreamApi version 2.18.1

Is this a new or an existing app?
New app

Repro

Debug an ASP.NET 8.0 application using multiple IDP's and Azure Web PubSub.

// IDP 1
builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
                .AddMicrosoftIdentityWebApi(builder.Configuration.GetSection("EntraExternalID"))
                .EnableTokenAcquisitionToCallDownstreamApi()
                .AddDownstreamApi("ServiceA", builder.Configuration.GetSection("ServiceA"))
                .AddDownstreamApi("ServiceB", builder.Configuration.GetSection("ServiceB"))
                .AddInMemoryTokenCaches();

// IDP 2
builder.Services.AddAuthentication().AddMicrosoftIdentityWebApi(builder.Configuration.GetSection("EntraID"), "EntraID");

// Add Web PubSub Service Client
builder.Services.AddWebPubSub(options =>
{
    var config = builder.Configuration.GetSection("Config").Get<Configuration<Config>>();
    options.ServiceEndpoint = new WebPubSubServiceEndpoint(config.ConnectionString);
}).AddWebPubSubServiceClient<webpubsub>();

// standard init in between e.g. var app = builder.Build();

// Further down map web pubsub event handler
app.UseAuthentication();
app.UseAuthorization();
app.MapControllers();
app.MapWebPubSubHub<webpubsub>("/eventhandler/{*path}");
app.Run();

Expected behavior
Error is not observed when debugging on Windows via Visual Studio.

Actual behavior
The call to app.MapWebPubSubHub<webpubsub>("/eventhandler/{*path}"); triggers System.InvalidOperationException: 'Cannot resolve scoped service 'Microsoft.Identity.Abstractions.IDownstreamApi' from root provider.' only when debugging via Visual Studio (latest version - 17.9.6) on Windows. When run in a Linux Container the app runs fine.

Possible solution
N/A

What is WebAppPubSubHub? would it require IdWeb as a singleton?
You probably want to move this bug to Microsoft.IdentityWeb.Web btw?

[Johno-ACSLive]

The SDK Azure.Messaging.WebPubSub is for the Azure Web PubSub service. This is workign when running via a Linux docker container, just not when debugging on Windows using Visual Studio so I don't think changing ID Web to a singleton will fix this. It depends on how things are being registered under the hood.

It's possible to be an issue in Microsoft.Identity.Web.DownstreamApi - from memory IDownstreamApi had been moved around and changed in the past so I don't recall why I logged it to this repo.
