VS Code - Debug doesn't work if app host fails before build

[afscrome]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

If you have an app host that fails before it gets built, the VS Code extension doesn't clearly highlight there was an error.

Expected Behavior

Whilst there is a warning, it doesn't really tell you what the problem is, I'd expect an error in red text, and including the stack trace from the app host (about the duplicate resource name)

Steps To Reproduce

Take the below app host that fails because I try to add two resources with the same name

Run it in via dotnet run, and you'll you'll break very clearly on the second line.

Run it via VS Code, and you don't get any indication

var builder = DistributedApplication.CreateBuilder(args);

builder.AddContainer("nginx", "nginx");
builder.AddContainer("nginx", "nginx");

using var app = builder.Build();

@afscrome I removed the bug label as github has first class support for issue types.
