Azure-webjobs-sdk: Document how AddScoped works to be per function calls

[jsgoupil]

Even though as it seems to have been fixed, no information has been provided regarding how to use AddScoped properly per function calls.

The original bug is here:
https://github.com/Azure/azure-webjobs-sdk/issues/1950

After a full month, we have received no answers, no commits, no documentation explaining how this works.

I am opening this bug as an actionable item for the team to respond properly.

Just a heads up: AddScoped is not fixed as far as I can tell. I still am getting my dependencies behaving like singletons.

I can confirm this issue is not fixed in v3.0.6 (of Webjobs.Extensions.Storage BlobTrigger)

Edit: this appears to be working when adding scoped dependencies manually, I am running into an issue with this code always returns the same instance of CustomUserManager

builder.Services
                .AddIdentityCore<CustomUser>()
                .AddEntityFrameworkStores<CustomUserDBContext>()
                .AddUserManager<CustomUserManager>()

Edit 2: Registering like this respects scoping as expected

            builder.Services
                .AddIdentityCore<CustomUser>()
                .AddEntityFrameworkStores<CustomUserDBContext>();
            builder.Services.AddScoped(typeof(CustomUserManager));
