silverlight from 4 to 5 upgrade ria services compilation error

Question

I've upgraded silverlight project from 4 to 5 and now have compilation error where I load data to the DomainContext:

Context.Load(Context.GetMyEntityQuery(), LoadBehavior.RefreshCurrent, null, null);


The call is ambiguous between the following methods or properties: 

'System.ServiceModel.DomainServices.Client.DomainContext.Load<MyEntity>(System.ServiceModel.DomainServices.Client.EntityQuery<MyEntity>, System.ServiceModel.DomainServices.Client.LoadBehavior, System.Action<System.ServiceModel.DomainServices.Client.LoadOperation<MyEntity>>, object)
'System.ServiceModel.DomainServices.Client.DomainContext.Load          (System.ServiceModel.DomainServices.Client.EntityQuery,           System.ServiceModel.DomainServices.Client.LoadBehavior, System.Action<System.ServiceModel.DomainServices.Client.LoadOperation>,           object)' 

Any ideas how to fix this (and I have > 100 such errors)?

Edit

Calling like this helps:

Context.Load<MyEntity>(Context.GetMyEntityQuery(), LoadBehavior.RefreshCurrent, null, null);

The culprit is this overload (assembly System.ServiceModel.DomainServices.Client.dll, v2.0.5.0)

[EditorBrowsable(EditorBrowsableState.Never)]
public virtual LoadOperation Load(EntityQuery query, LoadBehavior loadBehavior, Action<LoadOperation> callback, object userState);

together with this

public LoadOperation<TEntity> Load<TEntity>(EntityQuery<TEntity> query, LoadBehavior loadBehavior, Action<LoadOperation<TEntity>> callback, object userState) where TEntity : Entity;

It seems the later is enough so why the former is included? Anyway, will investigate further (it seems I reference the latest ria services 1.0 SP2, cleaning everything and rebuilding not helping).

Answer 1

I used to load data to DomainContext in the following way.

public void GetPersonObjectDataFromService(Action<LoadOperation<TempPersonDTO>>    loadData)
    {                                           
          var query1 = this.tpDataProviderContext1.GetPersonObjectDataFromServiceQuery();
          tpDataProviderContext1.Load(query1, LoadBehavior.RefreshCurrent, loadData, null);
    }

TempPersonDTO is Class which having data. Thank you.
