Hi Friends,
In our Project we are working WPF with MVVM using Linq and WCF Rest Services.
We are facing some problem in WCF Rest Service .We are creating Interface like below,
[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
[FaultContract(typeof(DEErrorProvider))]
Tuple<ObservableCollection<DEEmployee>, DEErrorProvider> getEmploteeList();
In above Mark Line in ResponseFormat if we are using Json means we are getting the below Error
"The underlying connection was closed: The connection was closed unexpectedly."
If we use Xml in ResponesFormat it is working fine. But we need JSON Format.
In BL we are creating Method like below.
public Tuple<ObservableCollection<DEEmployee>, DEErrorProvider> getEmploteeList ()
{
ContactCollection = new ObservableCollection<DEEmployeet>();
ErrorCollection = new DEErrorProvider();
try
{
using (EmployeeEntities EmpEntity = new EmployeeEntities())
{
Here we are creating our Business Logic with Linq Query Collection.
}
ErrorCollection.ErrorResult = true;
}
catch (Exception ex)
{
ErrorCollection.ErrorMessage = ex.Message;
ErrorCollection.ErrorTrace = ex.StackTrace;
ErrorCollection.ErrorResult = false;
}
return new Tuple<ObservableCollection<DEEmployee>, DEErrorProvider>(EmployeeCollection, ErrorCollection);
}
Please help me to solve this problem.
