i am working on rest service which is developed using WCF App. Service is working both xml and json format as rest. And i have to handle errors therefore i developed a ErrorHandler which is derived from IErrorHandler.



    public class ErrorHandler : IErrorHandler
{
public bool HandleError(Exception error)
{
return true;
}

public void ProvideFault(Exception exception, MessageVersion messageVersion, ref Message message)
{
CommonManager.Log($"Message:{exception.Message}, Stack Trace:{exception.StackTrace}");
var response = CommonManager.CreateResponse(exception.Message);
message = Message.CreateMessage(messageVersion, string.Empty, response, new DataContractJsonSerializer(typeof(ContainerModel<object>)));
var wbf = new WebBodyFormatMessageProperty(WebContentFormat.Json);
message.Properties.Add(WebBodyFormatMessageProperty.Name, wbf);
var rmp = new HttpResponseMessageProperty();
message.Properties.Add(HttpResponseMessageProperty.Name, rmp);
rmp.StatusCode = System.Net.HttpStatusCode.OK;
}
}


Below you can see XML response. The root attr type is "object".



   <s:Body>
<root type="object">
<Data type="null"/>
<IsSucceeded type="boolean">false</IsSucceeded>
<Message>The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:data. The InnerException message was 'There was an error deserializing the object of type CosmosXIAMWebServices.Models.UserModel. The value 'asd' cannot be parsed as the type 'Int32'.'. Please see InnerException for more details.</Message>
</root>




Normally if request is sucessfull. The root attr type is "AddOrUpdateUserResponse";



   <s:Body>
<AddOrUpdateUserResponse xmlns="http://tempuri.org/">
<AddOrUpdateUserResult xmlns:a="http://schemas.datacontract.org/2004/07/CosmosXIAMWebServices.Models" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<a:Data>
xx
</a:Data>
<a:IsSucceeded>false</a:IsSucceeded>
<a:Message>Username is already exist with that user code</a:Message>
</AddOrUpdateUserResult>
</AddOrUpdateUserResponse>




And i need response type to be same during error and success.



Thanks in advance.
