Hi, im doing something whit farseer and W8 i have this code to create the circle shape, but dont move, nay missing step.
_world = new FarseerPhysics.Dynamics.World( xna.Vector2.Zero);
Vertices circle = PolygonTools.CreateCircle(50, 25);
List<Vertices> _listaCirculo = new List<Vertices>();
_listaCirculo.Add(circle);
Body circleBudy = BodyFactory.CreateCompoundPolygon(_world, _listaCirculo, 1, new xna.Vector2(10,10));
circleBudy.BodyType = BodyType.Dynamic;
circleBudy.Position = new xna.Vector2(200, 200);
and using this code for draw the circle whit SharpDX
foreach (Fixture fixture in circleBudy.FixtureList)
{
PolygonShape pol = (PolygonShape)fixture.Shape;
DrawingPointF pointStart;
DrawingPointF pointEnd;
for (int i = 0; i < pol.Vertices.Count; i++)
{
pointStart.X = pol.Vertices[i].X;
pointStart.Y = pol.Vertices[i].Y;
if (i == (pol.Vertices.Count  1))
{
pointEnd.X = pol.Vertices[0].X;
pointEnd.Y = pol.Vertices[0].Y;
}else
{
pointEnd.X = pol.Vertices[i + 1].X;
pointEnd.Y = pol.Vertices[i + 1].Y;
}
deviceContext.DrawLine(pointStart, pointEnd, brush);
}
}

The vertices of a shape are in local coordinates. You should apply the body transform to them before drawing. See the DebugViewXNA for an example.
