How to create a polygon in a workflow?

Hi.  I'm trying to add a polygon markup through a workflow.  I'm able to add a point just fine but am having no luck adding a polygon.

 

I've defined a variable "poly" with a type of ESRI.ArcGIS.Client.Geometry.Polygon.  I then use an Assign activity and set poly to be:

 

New ESRI.ArcGIS.Client.Geometry.Polygon([[7655000,613000],[7655000,620000],[7675000,620000],[7675000,613000],[7655000,613000]])

 

However, it won't compile.  Am I missing something obvious?

 

As an aside, what's the best place to view documentation on the ESRI.ArcGIS.Client.Geometry namespace?  Is it the ArcGIS API for Javascript?  ArcGIS API for Silverlight?  I'm never sure where to look.

 

Thanks!

 

Chris

  forgot to actually tell you where I went for reference: https://developers.arcgis.com/javascript/jsapi/polygon-amd.html

  Thanks Marshall!  Quite a tricky set of procedures.... But it got me what I needed!

   

  What I'm not sure about is why the "new Polygon(coordinates)" constructor doesn't work...

  Yeah, I know, you have me intrigued.  I got this to at least compile, but it is still not an inline constructor (not sure if it works:

   

  thePolygon = new Polygon

   

  thePolygon.rings(0) = new PointCollection(new MapPoint() {new MapPoint(7655000,613000), new MapPoint(7655000,620000),new MapPoint(7675000,620000), new MapPoint(7675000,613000), new MapPoint(7655000,613000)})

   

   I haven't tested it, just happy I could compile it before the end of the day...I'll test tomorrow
