WSHttpBinding Class

Represents an interoperable binding that supports distributed transactions and secure, reliable sessions.

Namespace:  System.ServiceModel
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public class WSHttpBinding : WSHttpBindingBase

The WSHttpBinding is similar to the BasicHttpBinding but provides more Web service features. It uses the HTTP transport and provides message security, as does BasicHttpBinding, but it also provides transactions, reliable messaging, and WS-Addressing, either enabled by default or available through a single control setting.

The following sample code shows how to use the WSHttpBinding class.

using System;
using System.ServiceModel;
using System.Collections.Generic;
using System.IdentityModel.Tokens;
using System.Security.Cryptography.X509Certificates;
using System.ServiceModel.Channels;
using System.ServiceModel.Security;
using System.ServiceModel.Security.Tokens;
using System.Security.Permissions;

    [OperationContract(IsOneWay = false)]
    double Subtract(double n1, double n2);
    [OperationContract(IsOneWay = false)]
    double Multiply(double n1, double n2);
    [OperationContract(IsOneWay = false)]
    double Divide(double n1, double n2);
