Problem in adding Custom Provider for Work Management Service

Question

Hello,
I'm facing an issue in adding custom provider for work management service. As you are aware, Work management service is a Provider model and we
can integrate with other systems by adding custom providers. So with that confidence, i have started writing a connector as mentioned below.
Step - 1: Added new provider xml in the below path
"C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\CONFIG\WorkManagementService\Providers"
Provider Name: provider.bizagitasklist
Provider XML Content: 
<Provider ProviderKey="DAA52AF3-A147-4086-8C0C-82D2F83A089D" OverrideProviderKey="" Assembly="adidas.TaskProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5d6f3e6be60a351b" > </Provider>
Step -2: Added a class which inherits "IWmaTaskProvider" and implemented the override methods.
public class BizAgiTaskListProvider : IWmaTaskProvider
public string LocalizedProviderName
get { return "BizAgiTaskListProvider"; }
public string ProviderName
get { return "BizAgiTaskListProvider"; }
public Microsoft.Office.Server.WorkManagement.CalloutInfo GetCalloutInfo(IWmaTaskContext context, string taskExternalKey, string locationExternalKey)
return null;
public DashboardExtensionInfo GetDashboardExtensionInfo(IWmaBasicProviderContext context)
return new DashboardExtensionInfo { ClassName = "SP.UI.SharePointExtension" };
public BulkEditResult HandleBulkEdits(IWmaTaskContext context, BulkEdit updates)
return null;
public TaskEditResult HandleTaskEdit(IWmaTaskContext context, BaseAggregatorToProviderTaskUpdate taskUpdate)
return null;
public void RefreshSingleTask(IWmaTaskRefreshContext context, string externalKey)
public void RefreshTasks(IWmaTaskRefreshContext context)
//context.WriteProviderCustomData(
Step – 3: Written a class to fetch the tasks from BizAgi System which has method to provide the task data.
But I’m not able to feed those tasks in the class written in Step – 2 as I’m able to find any method which will take Tasks as Input and I’m not
sure about the format of tasks.
I’m able to debug the provider, and the breakpoint hitting in only one method and two properties.
(LocalizedProviderName, ProviderName, GetDashboardExtensionInfo).
Can you please help me to proceed further in implementing the above solution?
Best Regards
Mahesh

Hi Mahesh,
Although the implementation of work management service application is based on the provider model, I reckon the current SP 2013 RTM does not support custom providers. Only SharePoint task lists, Project server and MS Exchange are supported for now.
