can guide me on how to

1. consume wcf service in mvvm light
2. what changes should make in viewmodel , viewmodellocator collection of data wcf service.
3. how bind data gridview in mainpage.xaml

below code have implimented,

mainviewmodel.cs

using galasoft.mvvmlight; using nyntraonlineshopping.nyntraservicereference; using system.collections.objectmodel;  namespace nyntraonlineshopping.viewmodel {     public class mainviewmodel : viewmodelbase     {         readonly nyntraserviceclient _clientcontext = new nyntraserviceclient();                  private observablecollection<product> _products = new observablecollection<product>();          public observablecollection<product> products         {             { return _products; }             set { _products = value; }         }                 public mainviewmodel()         {                         _clientcontext.getallproductscompleted += clientcontextgetallproductscompleted;         }          void clientcontextgetallproductscompleted(object sender, getallproductscompletedeventargs e)         {             _clientcontext.getallproductsasync();         }     } }

viewmodellocator.cs

namespace nyntraonlineshopping.viewmodel {         public class viewmodellocator     {         static viewmodellocator()         {             servicelocator.setlocatorprovider(() => simpleioc.default);              if (viewmodelbase.isindesignmodestatic)             {                 simpleioc.default.register<inyntraservice, nyntraserviceclient>();             }             else             {                 simpleioc.default.register<inyntraservice, nyntraserviceclient>();             }              simpleioc.default.register<mainviewmodel>();         }         [system.diagnostics.codeanalysis.suppressmessage("microsoft.performance",             "ca1822:markmembersasstatic",             justification = "this non-static member needed data binding purposes.")]         public mainviewmodel main         {                         {                 return servicelocator.current.getinstance<mainviewmodel>();             }         }                [system.diagnostics.codeanalysis.suppressmessage("microsoft.performance",             "ca1822:markmembersasstatic",             justification = "this non-static member needed data binding purposes.")]         public productviewmodel product         {                         {                 return servicelocator.current.getinstance<productviewmodel>();             }         }                 public static void cleanup()         {         }     } }

and mainpage.xaml

<usercontrol xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"  x:class="nyntraonlineshopping.mainpage"              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"              xmlns:d="http://schemas.microsoft.com/expression/blend/2008"              xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"              mc:ignorable="d"              height="300"              width="300"              datacontext="{binding source={staticresource locator}, path=viewmodelname}">                    <usercontrol.resources>         <resourcedictionary>             <resourcedictionary.mergeddictionaries>                 <resourcedictionary source="skins/mainskin.xaml" />             </resourcedictionary.mergeddictionaries>         </resourcedictionary>     </usercontrol.resources>      <grid x:name="layoutroot">          <telerik:radgridview itemssource="{binding products}" autogeneratecolumns="true" >                      </telerik:radgridview>            </grid> </usercontrol> 

i not getting errors. not getting result aswell.

public mainviewmodel() {     _clientcontext.getallproductscompleted += clientcontextgetallproductscompleted;     _clientcontext.getallproductsasync(); }  void clientcontextgetallproductscompleted(object sender, getallproductscompletedeventargs e) {     if (e.error == null)     {         return;     }      foreach (product item in e.result)     {         products.add(item);     } }
