title: Create a DbGeography Polygon from a collection of DbGeography Points
body: <p>Can anyone tell me how I can create a DbGeography object of type 'Polygon' from a Collection of DbGeography objects of type 'POINT'</p>
  
  <p>So far I've got this which creates the polygon but I'm missing how the initial step.</p>
  
  <pre><code>1. DbGeography multipoint = DbGeography.MultiPointFromText("MULTIPOINT(53.095124 -0.864716, 53.021255 -1.337128, 52.808019 -1.345367, 52.86153 -1.018524)", 4326)
  
  2. DbGeometry temp_multipoint = DbGeometry.MultiPointFromBinary(multipoint.AsBinary(), 4326)
  
  3. DbGeography polygon = DbGeography.PolygonFromBinary(temp_multipoint.ConvexHull.AsBinary(), 4326); (RESULT)
  </code></pre>
  
  <p>The problem is creating the initial multipoint geography object from a list of DbGeography(POINTS)</p>
