Debugging Caliburn Micro Binding issues

I was looking at this Caliburn Micro question on stackoverflow

https://stackoverflow.com/questions/65362824/datagrid-column-binding-to-class

One thing you can do in Caliburn.Micro to see what is going on with the Binding is to add a logger. This class inherits from ILog to write to the console window.

public class DebuggingLogger : ILog
{
    #region Fields
    private readonly Type _type;
    #endregion

    #region Constructors
    public DebuggingLogger(Type type)
    {
        _type = type;
    }
    #endregion

    #region Helper Methods
    private string CreateLogMessage(string format, params object[] args)
    {
        return string.Format("[{0}] {1}",
            DateTime.Now.ToString("o"),
            string.Format(format, args));
    }
    #endregion

    #region ILog Members
    public void Error(Exception exception)
    {
        Debug.WriteLine(CreateLogMessage(exception.ToString()), "ERROR");
    }

    public void Info(string format, params object[] args)
    {
        Debug.WriteLine(CreateLogMessage(format, args), "INFO");
    }

    public void Warn(string format, params object[] args)
    {
        Debug.WriteLine(CreateLogMessage(format, args), "WARN");
    }
    #endregion
}

To use it in the Bootstapper contractor register the logger.

    public Bootstrapper()
    {
        Initialize();
         LogManager.GetLog = type => new DebuggingLogger(type);
    }

Now when you run the app you see info on what is going on in the output window with the bindings

If there is an error you will see something like this
