           /// <summary> 
        
           /// The first row of the matrix. 
        
           /// </summary>

           public Vector4 Item0;

Since they are rows, it would make a lot more sense to call them "Row0/Row1" etc.

Wrapper properties for "Item0/Item1" etc can be used to preserve API compatibility if desired.

	/// <summary>
	/// The first row of the matrix.
	/// </summary>
	[Browsable( false )]
	public Vector4 Item0;
