Missing dependency : Program does not run (and freezes)

[maxime-paquatte]

Here's an example of code where a dependency is missing. The program displays no error and freezes.

using Cocona;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;

var builder = CoconaApp.CreateBuilder();
builder.Services.AddSingleton<Class1>();
builder.Logging.AddConsole()
    .AddFilter(f => f >= LogLevel.Debug);

var app = builder.Build();
app.AddCommands<MyCommands>();
app.Run();

public class MyCommands
{
    public MyCommands(Class1 c1){}

    public void DoStuff()
    {
        Console.WriteLine("Hello, World!");
    }
}

public class Class1
{
    public Class1(Class2 c2){}
}

public class Class2{}

the output is as follows, nothing else happens:

dbug: Microsoft.Extensions.Hosting.Internal.Host[1]
      Hosting starting
dbug: Microsoft.Extensions.Hosting.Internal.Host[2]
      Hosting started

I also experienced this. Took me a while to realize it was caused by missing dependencies.

Experiencing the same issue; any advice on how to capture dependency resolution errors?
