Error trying to use sample code for Custom Brush

[JerryWar]

Hi here is a picture which contains sample code I copied exactly. I made sure I was using System.Windows.Media yet it still generates an error I have not figured out how to avoid.
the error by being more specific.

Here is the code:

// initiate new solid color brush with custom blue color
Brush myBrush = new SolidColorBrush(Color.FromRgb(56, 120, 153));
myBrush.Freeze();
Draw.Line(this, "tag1", true, 10, 1000, 0, 1001, myBrush, DashStyleHelper.Dot, 2);

Here is error followed by source I copied from

	Error
	'Brush' is an ambiguous reference between 'System.Windows.Media.Brush' and 'SharpDX.Direct2D1.Brush'
	'SolidColorBrush' is an ambiguous reference between 'System.Windows.Media.SolidColorBrush' and 'SharpDX.Direct2D1.SolidColorBrush'

I was able to find a solution to this from an earlier post.
No response necessary.
