Memory leak issue of Graphic Layer

hhhh

I have a test program. There are 2 buttons. One button is used for adding 2000 graphics, the second one is used for
clear all graphics.
  By monitoring the memory, I found the memory used is keeping increasing when I click "Add", "Clear", "Add", "Clear", .....

    Is there a way to solve the memeory leak?

   Thanks

if ((sender as Button).Name.Equals("btnClear"))
          {
              (dpMap.Layers["SelectionHighLightLayer"] as GraphicsLayer).Graphics.Clear();
              (dpMap.Layers["SelectionHighLightLayer"] as GraphicsLayer).ClearGraphics();
            
              GC.Collect();
              GC.GetTotalMemory(true);
              GC.WaitForPendingFinalizers();
          }
          else
          {
              ESRI.ArcGIS.Client.Geometry.Geometry geom = new MapPoint(-3105,5650533) ;

              for (int i = 0; i < 2000; i++)
              {
                  (dpMap.Layers["SelectionHighLightLayer"] as GraphicsLayer).Graphics.Add(new Graphic()
                                {
                                    Geometry = geom,
                                    Symbol = ResultsMarkerSymbol
                                });
              }
          }

Hello,

I'm also very interested in this. We're currently using version 2.4 and have the same problem. Even deleting a layer does not free the memory and this is becoming a problem when the users run the application through Citrix. I don't know if this is related, but hiding a layer doesn't affect memory either. When Silverlight doesn't have to render as many vertices, shouldn't the memory usage decrease? Is there any way to solve this myself, through source code at GitHub or where is the code concering this located, if it's open?
