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.

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;
}
}
}

Error: Cannot obtain Metadata; using WCF Test client, C#, and trying to implement webhttpbinding and json

I'm getting the fabled Error: Cannot obtain Metadata from... message, particularly http://localhost:1640/Service1.svc I've scoured stackoverflow and Google and, so far, none of it has helped. I created a new product to dumb it down and it's still not working. So I am here asking for help.
I'm trying to setup a WCF Service that uses JSON, which means I need to use webhttpbinding, in C#. When I use the WCF Test Client, I get the aforementioned metadata error. I'm using Visual Studio Express 2010 and the target framework. I've been at this for two days and cannot understand why or what is the problem.
I would appreciate any help. Thank you.

Take a look at this link
It states the following:
WebHttpBinding is a REST-based binding - REST does not expose
metadata like WSDL/XSD contrary to SOAP.

In addition to bruno bologna's answer and link, the link at WCF REST Service not visible in WCFTestClient also provides some very useful information. Basically, the reason why it's not working is the WCFTestClient is not designed for web (think JSON). It hooks in through SOAP. If I have a service that is dependent on JSON, I cannot test it through the WCFTestClient.
I see that it is possible to modify the client configuration file in WCFTestClient to enable web binding, but that may be because of future-proofing for WADL or if someone writes a WADL service extension. That's just specultation on my part, though. Otherwise, it doesn't appear one can test WCF Service with JSON using the WCFTestClient tool.

No connection could be made because the target machine actively refused it 127.0.0.1:8000

I have created the WCF service and trying to host in Managed Windows Service (followed article). The service is up and running in services.
When trying to add the URL in the client application (net.tcp://localhost:8000/UserManagement) I get the error:
Metadata contains a reference that cannot be resolved:
'net.tcp://localhost:8000/UserManagement'. Could not connect to
net.tcp://localhost:8000/UserManagement. The connection attempt lasted

in the current solution, try building the solution and adding the

You need to use the address
net.tcp://localhost:8000/UserManagement/mex
when you are configuring your service reference.
Alternatively your metadata endpoint should use the mexHttpBinding and you should set your httpGetEnabled to true in your service behavior
<serviceMetadata httpGetEnabled="true"/>

I also faced the same issue after following MSDN link you provided. There is a error in that code.
In you OnStart method,
serviceHost = new ServiceHost(typeof(UserManagementService));
instead of creating ServiceHost for UserManagementService, use your actual WCF service class name here. This line of code will create an instance of windows service and not the WCF service. I was able to fix mine using that.
