WCF Connection Reset

I'm creating a WCF Service, and it's working fine while I'm connecting it to a WinForms Client. But I want to access it throught the browser. Some methods are working fine, but when I'm trying to send back an object that includes multiples objects it returns the error message "A connection was reset"... I was trying to test my service with ARC and with JQuery Ajax, and all the cases I received the same error.
I almost forgot telling you, this issue only happens if I create a instance to Period attribute. If I return the object clear, I don't have any issue.
I share to you a test I made based on the original code. I hope you could help me.

I just found the same issue with a piece of code in a WCF service I'm working on, that is (now) using the webHttpBinding (for REST clients). The culprit was the property "IsReference=true" in a DataContract class. I needed that flag set to TRUE because the graph of objects contains circular references; this way the returned response has a lot less bytes than if the real objects were serialized.
I don't know why this works with SOAP and other bindings but not with webHttpBinding, but since I needed to add REST support, the service stopped working when a DataContract class with IsReference=true was being returned.
My temporary solution was to create another class with the same properties as the original, but without the IsReference property. I need to investigate this further but in the meantime I hope this helps.

How to make WCF web-service consumable by Team Foundation Server Web Hooks?

I'm having trouble with Team Foundation Server 2015 Web Hooks (https://www.visualstudio.com/get-started/webhooks-and-vso-vs)
I can create web hook on TFS side and it successfully uses RequestBin WebService. But when I create the WCF Web service - have errors all the time.
First of all I get #Cannot process the message because the content type 'application/json; charset utf-8' was not the expected type 'text/xml;charset utf-8'.(415)"
I've read a lot of articles and related questions here.
Tried to add Factory="System.ServiceModel.Activation.WebServiceHostFactory" to .svc file. After it I've got 404 error while consuming service and no endpoint found while trying to open it's WSDL

What is happening to the wcf data?

I am adding objects sent from a client to a list which is at the service, my issue is this, during debugging I see that as soon as i return from the main service to the client the list turns to 0. It's like the list gets emptied and as soon as the flow of the program returns to the client and then when the client sends data to the service the data are there, as soon as i enter the method of the service the list gets filled with the old data. I would like to access these data from another part of the program but i always see the list empty. Any tips?

As per my comment you need to setup the ServiceContract's SessionMode and also the ServiceBehavior's InstanceContextMode. The default InstanceContextMode is PerCall which means that your list will not be preserved. You need to change it to use PerSession. See below for fully working example (.NET 4):
Service Side Code:
using System.Collections.Generic;
using System.ServiceModel;
namespace WcfService1
{
[ServiceContract(SessionMode = SessionMode.Required)]
public interface IService1
{
[OperationContract]
int AddData(string data);
[OperationContract]
List<string> GetData();
}
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
public class Service1 : IService1
{
private readonly List<string> _myList = new List<string>();
public int AddData(string data)
{
_myList.Add(data);
return _myList.Count;
}
public List<string> GetData()
{
return _myList;
}
}
}

using System.Collections.Generic;
using ConsoleApplication1.ServiceReference1;
namespace ConsoleApplication1
{
internal class Program

using (var service = new Service1Client())
{
// Add items...
int itemCount;
itemCount = service.AddData("Test Item 1");
Console.WriteLine("Service now holds {0} items", itemCount);
itemCount = service.AddData("Test Item 2");
Console.WriteLine("Service now holds {0} items", itemCount);
itemCount = service.AddData("Test Item 3");
Console.WriteLine("Service now holds {0} items", itemCount);
// Get all of the items added...
List<string> listFromService = service.GetData();
foreach (var listItem in listFromService)
{
Console.WriteLine(" * {0}", listItem);
}
Console.WriteLine();
}
Console.ReadKey();
}
}
}

<?xml version="1.0" encoding="utf-8" ?>

Note: I had to ensure that wsHttpBinding was used as basicHttpBinding does NOT support sessions.

500 Interval Server Error while accessing WCF service from http and Google Chrome Extension Simple REST Client

THis is the service which I created for Android device to post data but this service doesn't work for me. I called this service through an Android but nothing happens just received an error message of -500 in LogCat. I also check this service on HTTP and SIMPLE REST Client (Google Chrome Extension) but received an error message. Error message is given below. and this service is also published on IIS.
Error Message
The message with Action '' cannot be processed at the receiver,due to a ContractFilter mismatch at the EndpointDispatcher.
This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver.
Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None)
These are the params which im passing to the service:
{"mycar":{"Name":"a","Make":"gfgfd ","Model":"web "}}
and here is the service source code
namespace CarSercive
{
[ServiceBehavior(AddressFilterMode=AddressFilterMode.Any)]
public class Service1 : IService1
{
// myCar test = new myCar();
public void UpdateMyCar(myCar mycar) {
string strConnectionString = ConfigurationManager.ConnectionStrings["Database1"].ConnectionString;
SqlConnection conn = new SqlConnection(strConnectionString);
conn.Open();
using (SqlCommand cmd = new SqlCommand("Insert into TestingTable (Name,Make,Model) Values (#Name,#Make,#Model)", conn)) {
cmd.Parameters.AddWithValue("#Name", mycar.Name);
cmd.Parameters.AddWithValue("#Make", mycar.Make);
cmd.Parameters.AddWithValue("#Model", mycar.Model);
int queryResult = cmd.ExecuteNonQuery();
} conn.Close();

You need to add a JSON endpoint to your web.config file.
<system.serviceModel>
<domainServices>
<endpoints>
<add name="JSON" type="Microsoft.ServiceModel.DomainServices.Hosting.JsonEndpointFactory, Microsoft.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</endpoints>
</domainServices>
make sure to link to the assembly Microsoft.ServiceModel.DomainServices.Hosting.JsonEndpointFactory in your project

WCF REST call returns "Method not allowed" exception

I am trying to create a WCF Restful Service.
Here is my contract: (The ActivateUser class extends the BaseResult class).
namespace SmartShopServerContract {
[ServiceContract]
public interface IService {
[OperationContract]
[WebGet(RequestFormat=WebMessageFormat.Json, ResponseFormat=WebMessageFormat.Json, UriTemplate="au/{eMail}/{password}/{idHandy}")]
ActivateUserResult ActivateUser(string eMail, string password, string idHandy);
}
// Basisklasse der Resultate --> alle Resultate haben einen definierten Status!
[DataContract]
public abstract class BaseResult {
private string status;
public BaseResult(string status) {
this.status = status;
}
[DataMember]
public string Status {
get { return this.status; }
}
}
// Result für ActivateUser
[DataContract]
public class ActivateUserResult : BaseResult {
public ActivateUserResult(string status)
: base(status) {
}
[DataMember]
public string CryptedPassword { get; set; }
}
}
Here is the implementation of the Service:
namespace SmartShopServerService {
public class ServiceSmartShop : IService {
public ActivateUserResult ActivateUser(string eMail, string password, string idHandy) {
return new ActivateUserResult("OK") {
CryptedPassword="testatsa"
};
}
And there is the Web.config file:
<?xml version="1.0"?>

I am testing this with the "VS2012 native tool commant prompt" like this:
svcutil.exe http://localhost:51162/SmartShopService.svc/au/data1/data2/data3
The code is being executed, but I am still getting a Method not allowed (405) exception.
Any thoughts on that?
--> currently local use
--> IIS Express (Visual Studio 2012)

You're using svcutil to create a proxy for a "RESTful WCF service". This does not work. The quick reason is that Web endpoints do not expose metadata for the svcutil tool to know what requests it needs to send to it. The long version is on the linked blog post.

The problem was the base class (BaseResult) for the ActivateUser class --> BaseResult
It seems like that it is not possible to extend a DataContract class and expect it to work.
Now i am using a Interface instead of a base class
public interface IResult {
string Status{get;set;}
}
[DataContract]
public class ActivateUserResult : IResult {
[DataMember]
public string CryptedPassword { get; set; }
[DataMember]
public string Status { get; set; }
}
This is working....thats all i know ;)
