SharpDX - System.Drawing interoperability

Is it possible to get something drawn with default .net paint methods (System.Drawing methods) to a SharpDX Texture2D object so that i can display it as a texture? Preferably with the SharpDX Toolkit.

If yes, how?

edit: what i am trying so far:

Bitmap b = new Bitmap(100,100);
MemoryStream ms = new MemoryStream();
b.Save(ms, System.Drawing.Imaging.ImageFormat.Png);    
Texture2D tex = Texture2D.Load(g.device, ms); // crashing here
ms.Close();

  b.Save(ms, System.Drawing.Imaging.ImageFormat.Png);    
  Texture2D tex = Texture2D.Load(g.device, ms);

The Save() call leaves the memory stream positioned at the end of the stream. Which will confuzzle the Load() method, it can't read any data from the stream. You'll have to rewind the stream explicitly. Insert this statement between the two lines of code:

  ms.Position = 0;
