Consider removing the dependency between IApplicationLifetime and IApplicationLifetimeEvents

[davidfowl]

The following class will cause a circular dependency error in the DI system:

public class LifetimeEvents : IApplicationLifetimeEvents
{
    public LifetimeEvents(IApplicationLifetime lifetime)
    {

    }

    public void OnApplicationStarted()
    {
        
    }

    public void OnApplicationStopping()
    {
        
    }

    public void OnApplicationStopped()
    {

    }
}

This is because internally, the default implementation of IApplicationLifetime takes an IEnumerable<IApplicationLifetimeEvents>. The reason you might want to inject IApplicationLifetime is because you might want to call StopApplication at some point. Either way, the error is impossible to figure out without understanding how it's implemented.
