Web services/WCF binding on Client Machine

Step 1. Accessing Web services with impersonation Credential 

          1. Add Service reference in Project.
          2. Add Service NameSpace
                     using MyNameSpace.MyNameSpacee;
                         MyNameSpacee.MyWebServiceSoapClient myNameSpacee = new MyWebServiceSoapClient();





Step 2. change the binding in web.config/App.Config like below...



<system.serviceModel>
        <bindings>
            <basicHttpBinding>
              <binding name="MyWebServiceSoap">
                <security mode="TransportCredentialOnly">
                  <transport clientCredentialType="Ntlm" proxyCredentialType="None" realm=""/>
                  <message clientCredentialType="UserName" algorithmSuite="Default"/>
                </security>
              </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address=""
                binding="basicHttpBinding" bindingConfiguration="MyWebServiceSoap"
                contract="MyNameSpace.MyWebServiceSoap" name="MyWebServiceSoap" />
        </client>
    </system.serviceModel>

          3. Add Dynamically Address for current Web

  myNameSpacee.Endpoint.Address = new System.ServiceModel.EndpointAddress(SPContext.Current.Web.Url+"/_layouts/15/MyWebServices/MyWebService.asmx");

OR

Add Static Services Address in

Web.config/App.config like below inside Client Tag

 <client>
            <endpoint address="http://site:port/_layouts/15/MyWebServices/MyWebService.asmx""
                binding="basicHttpBinding" bindingConfiguration="MyWebServiceSoap"
                contract="MyNameSpace.MyWebServiceSoap" name="MyWebServiceSoap" />
        </client>



            myNameSpacee.ChannelFactory.Credentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
            myNameSpacee.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;



4. finally Call your WebMethod 


myNameSpacee.GetMYMethod();
