Not sure if this is an issue  Endpoint and binding both have the same name

In case if you are using WPF application using PRISM framework then configuration should exist in your start up project  i e  in the project where your bootstrapper resides    In short just remove it from the class library and put into a start up project

Just in case anyone hits the same problem whilst using WPF  rather than WCF or Silverlight    I had this error  when connecting to a Web Service   When my code was in the  main  WPF Application solution  no problem  it worked perfectly   But when I moved the code to the more sensible DAL-layer solution  it would throw the exception      Could not find default endpoint element that references contract  MyWebService MyServiceSoap  in the ServiceModel client configuration section  This might be because no configuration file was found for your application  or because no endpoint element matching this contract could be found in the client element    As has been stated by  Sprite  in this thread  you need to manually copy the  tag     For WPF apps  this means copying the  tag from the app config in my DAL solution to the app config in the main WPF Application solution

Had to add the service in the calling App config file to have it work  Make sure that you but it after all    This seemed to work for me

I had a run in with the same problem   My application was also a Silverlight application  and the service was being called from a class library with a custom UserControl that was being used in it   The solution is simple   Copy the endpoint definitions from the config file  e g  ServiceReferences ClientConfig  of the class library to the config file of the silverlight application   I know you d expect it to work without having to do this  but apparently someone in Redmond had a vacation that day

For those who work with AX 2012 AIF services and try to call there C  or VB project inside AX  x    and suffer from such errors of  could not find default endpoint     or  no contract found      go back to your visual studio  c   project and add these lines before defining your service client  then deploy the project and restart AX client and retry  Note  the example is for NetTcp adapter  you could easily use any other adapter instead according to your need    Uri Address   new Uri  net tcp   your-server Port gt  DynamicsAx Services your-port-name     NetTcpBinding Binding   new NetTcpBinding     EndpointAddress EndPointAddr   new EndpointAddress Address    SalesOrderServiceClient Client   new SalesOrderServiceClient Binding  EndPointAddr

I ran into the same issue  for whatever reason Visual Studio did not update the web config when I first added the service  I found that updating the Service Reference also fixed this issue   Steps    Navigate to the Service Reference Folder Expand it Right Click and Select update Service Reference Observe web Config be updated

You can also set these values programatically in the class library  this will avoid unnecessary movement of the config files across the library  The example code for simple BasciHttpBinding is -    BasicHttpBinding basicHttpbinding   new BasicHttpBinding BasicHttpSecurityMode None   basicHttpbinding Name    BasicHttpBinding YourName   basicHttpbinding Security Transport ClientCredentialType   HttpClientCredentialType None  basicHttpbinding Security Message ClientCredentialType   BasicHttpMessageCredentialType UserName   EndpointAddress endpointAddress   new EndpointAddress  http    lt Your machine gt  Service1 Service1 svc    Service1Client proxyClient   new Service1Client basicHttpbinding endpointAddress

Do you have an Interface that your  UserService  class implements   Your endpoints should specify an interface for the contract attribute   contract  UserService IUserService

Rename the output config produced by svcutil exe to app config  it worked for me

This problem occures when you use your service via other application If application has config file just add your service config information to this file  In my situation there wasn t any config file so I use this technique and it worked fine Just store url address in application read it and using BasicHttpBinding   method send it to service application as parameter This is simple demonstration how  I did it   Configuration config   new Configuration dataRowSet 0   ServiceUrl   ToString      var remoteAddress   new System ServiceModel EndpointAddress config Url     SimpleService PayPointSoapClient client        new SimpleService PayPointSoapClient new System ServiceModel BasicHttpBinding         remoteAddress   SimpleService AccountcredResponse response   client AccountCred request

Change the web config of WCF service as  endpoint address    binding  basicHttpBinding       previously binding  wsHttpBinding  After build the app  in  ServiceReferences ClientConfig    configuration  has the value  Then it will work fine

User · Answer

Not sure if it s really a problem  but I see you have the same name for your binding configuration      I usually try to call my endpoints something like  UserServiceBasicHttp  or something similar  the  Binding  really doesn t have anything to do here   and I try to call my binding configurations something with      Configuration   e g   UserServiceDefaultBinding   to avoid any potential name clashes   Marc
