Hello,
This is not urgent or a show stopper, but i just want to bring it to your attention...

When using builders and components interchangeably, the following code will fail due to the implicit "=" operator.

Ext.Net.ComboBox oComboBox = null ;

Ext.Net.ComboBox.Builder oComboBoxBuilder = oComboBox;
It fails at the overloaded operator...

// Ext.Net.ComboBox.Builder
/// <summary>
///
/// </summary>
public static implicit operator Builder(ComboBox component)
{
	return component.ToBuilder();
}
