Dashboard used wrong ports for the app

[KSemenenko]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

if port for api service is taken or auto assigned, dashboard can't get it.

logs for app

Microsoft.Hosting.Lifetime: Information: Now listening on: https://localhost:63961
Microsoft.Hosting.Lifetime: Information: Now listening on: http://localhost:63962
Microsoft.Hosting.Lifetime: Information: Application started. Press Ctrl+C to shut down.
Microsoft.Hosting.Lifetime: Information: Hosting environment: Development
Microsoft.Hosting.Lifetime: Information: Content root path: /Users/ksemenenko/Developer/SiloLinker/SiloLinker

as yout can see app started on 63961 and 63962

But in dashboard

as you can see ports are 7079 and 5079 so this is not right

Expected Behavior

dashboard should properly managed ports

Steps To Reproduce

No response

Looks like this is the same underlying issue as #9717 which we have an item on the backlog to address

@KSemenenko , one other thing to add, is that Aspire creates a proxy in front of the services. https://learn.microsoft.com/en-us/dotnet/aspire/fundamentals/networking-overview describes this. I'll close this as duplicate as we have work items tracking the issue with the dashboard showing running even though we failed to bind due to a port in use.
