Protocol Mapping in WCF 4.0 Hosted on Web App

Vijay Prativadi

Today, in this article let's dig out an interesting and wonderful concept. This concept is made life better and delivers high in throughput.

Question arises: What is Protocol Mapping?

In Simple Terms: It is set of configured protocols which intimate to use which type of binding based on particular address. It groups set of protocols that are responsible for transport protocols.

So, we all are good to go and implement this concept.

Now, let's get it started off

The Complete Code of IService1.cs looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WcfService1
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IService1
{
[OperationContract]
double Add(double a, double b);

[OperationContract]
double Sub(double a, double b);

[OperationContract]
double Mul(double a, double b);

[OperationContract]
double Div(double a, double b);

}
}

The Complete Code of Service1.svc looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WcfService1
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
public class Service1 : IService1
{
public double Add(double a, double b)
{
return a + b;
}

public double Sub(double a, double b)
{
return a - b;
}

public double Mul(double a, double b)
{
return a * b;
}

public double Div(double a, double b)
{
return a / b;
}

}
}

The Complete Code of Web.Config looks like this:

<?xml version="1.0"?>
<configuration>

<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<protocolMapping>
<add scheme="http" binding="basicHttpBinding" bindingConfiguration=""/>

</protocolMapping>
<behaviors>
<serviceBehaviors>
<behavior>

<serviceMetadata httpGetEnabled="true"/>

<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>

</configuration>

Now it's time for us to go and add protocols with unique URL and system user name. So the complete steps for doing this is described as below:

Start->Accessories->Run

When the Run window opens type: netsh

The command prompt will open, so now it's time for us to go and add protocols for user. So in the command prompt type:

netsh>http add urlacl url=http: //localhost:8000/Service user=Vijay-PC

Press Enter Now. The http will be successfully added and display a success message on prompt.

The Complete Code of WebForm1.aspx looks like this:

Now, we haven't yet done, when you run the application it displays an "addressacessdeniedException". This exception is thrown because it's one of the new security feature implemented in since release from Vista Operating System. It stops the user and whereby it can be handled by running the visual studio as in Administrator Mode. The reason behind it is protocols require administrator access rights and privileges. The Screenshot displayed below shows how to run visual studio in administrator mode. The Screenshot follows:

The Exception screenshot is given as below:

The Output of the Application looks like this:

The Addition Operation Output Application looks like this:

The Invalid Data Entered Output Application looks like this:
