c# - Memory consumption of wpfgfx_v0400.dll -

i developed in c#. after period used windowsforms, switch wpf. after time of developing realized application needs more time reduce memory consumption after running high process. winforms had no problem it. analyzed memory profiler , found wpfgfx_v0400.dll reserved memory , after not reduced. question function of library. know native wpf library , in context of graphic rendering in specially controls of wpf or object called library?

as quick fix can use method clear memory leak

  public class memorymanagement     {         /// <summary>         /// clear un wanted memory         /// </summary>         public static void flushmemory()         {             try             {                 gc.collect();                 gc.waitforpendingfinalizers();                 if (environment.osversion.platform == platformid.win32nt)                 {                     setprocessworkingsetsize(system.diagnostics.process.getcurrentprocess().handle, -1, -1);                 }             }             catch (exception e)             {             }         }          /// <summary>         /// set process working size         /// </summary>         /// <param name="process">gets process</param>         /// <param name="minimumworkingsetsize">gets minimum working size</param>         /// <param name="maximumworkingsetsize">gets maximum working size</param>         /// <returns>returns value</returns>         [dllimportattribute("kernel32.dll", entrypoint = "setprocessworkingsetsize", exactspelling = true, charset =           charset.ansi, setlasterror = true)]         private static extern int setprocessworkingsetsize(intptr process, int minimumworkingsetsize, int maximumworkingsetsize);     } 

add class application , call flushmemory method met memory leak.
