An existing connection was forcibly closed by the remote host. in WCF using database first approach - entity-framework

Question

I'm trying to display data in a table format, by joining two tables 'Users' and 'Company' with Foreign key relation.
When I directly writes the code in controller with working fine
public ActionResult Index()
{
var model = new UserModel();
model.Users = db.Users
.OrderBy(o => o.CreatedBy)
.Include(c => c.Company).ToList();
return View(model);
}
but when i place the same code in WCF is throwing exception..
public List GetUsersList()
{
try
{
using (ProductionEntities db = new ProductionEntities())
{
db.Configuration.LazyLoadingEnabled = false;
db.Configuration.ProxyCreationEnabled = false;
IQueryable<User> _users = db.Users
.OrderBy(o => o.CreatedBy)
.Include(c => c.Company);
return _users.ToList();
}
}
catch (Exception ex)
{
ExceptionData exceptionData = new ExceptionData();
exceptionData.ErrorMessage = "Error in GetUsersList";
exceptionData.ErrorDetails = ex.ToString();
throw new FaultException<ExceptionData>(exceptionData, ex.Message);
}
}
The below is the Stack Trace Inner exception :
InnerException: System.Net.WebException

Any idea???
Thank you,

Answer 1

That's due to the circular reference.
Check this link for Reference
also we need to set
ProductionEntities db = new ProductionEntities()
db.Configuration.LazyLoadingEnabled = false;
db.Configuration.ProxyCreationEnabled = false;
