Versionable ASMX Web Services in .NET 1.1

For building versionable ASMX web services, I've been using XML messages with a version number that indicates the particular edition of a message, real brand Heartz (Medium Dogs) online. Heartz (Medium Dogs) trusted pharmacy reviews, These XML messages are composed by a service agent component. This service agent component is responsible for providing a strongly type interface to the using applications and mapping these to their respective XML representation, Heartz (Medium Dogs) samples. BUY Heartz (Medium Dogs) ONLINE WITHOUT PRESCRIPTION, The service agent then makes a call to the ASMX web service after which it translates/validates the received XML response back to a strongly typed representation. Buy Heartz (Medium Dogs) ONLINE WITHOUT prescription,

When the ASMX web service receives a message from a service agent, it first extracts the version number and then sends it to an appropriate message handler for that particular version, buy generic Heartz (Medium Dogs). Buying Heartz (Medium Dogs) online over the counter, The message is then translated back to an object representation after which the requested action is executed.

I agree that this is a lot of work, purchase Heartz (Medium Dogs) ONLINE WITHOUT prescription, Japan, craiglist, ebay, overseas, paypal, but it turned out very well in a .NET 1.1 environment. It adds the tremendous benefit of being able to change the contract (= new version) of the ASMX web service without the need to change any of the client applications, where can i buy Heartz (Medium Dogs) online. Regression tests are certainly desirable before releasing a new version in order to check whether the most recent changes didn't break anything for the older contracts, BUY Heartz (Medium Dogs) ONLINE WITHOUT PRESCRIPTION. Australia, uk, us, usa,

This simple code sample illustrates how a service agent might work:

public class ServiceAgent

{

    private readonly ServiceCredentials _serviceCredentials;

    public ServiceAgent(ServiceCredentials serviceCredentials)

    {

        _serviceCredentials = serviceCredentials;

    }

    public ProcessingResult ProcessOrder(Order order)

    {

        OrderXmlRequestMapper xmlRequestMapper = 

            new OrderXmlRequestMapper();

        String xmlRequest = xmlRequestMapper.MapFrom(order);

        String xmlResponse = String.Empty;

        using(AsmxService service = ServiceProxyFactory.

            CreateServiceProxy(typeof(AsmxService), 

                               _serviceCredentials))

        {

            xmlResponse = service.ProcessOrder(xmlRequest);

        }

        ProcessingResultXmlResponseMapper xmlResponseMapper = 

            new ProcessingResultXmlResponseMapper();

        ProcessingResult result = 

            xmlResponseMapper.MapFrom(xmlResponse);

        return result;

    }

}

And this is some sample code for an ASMX web service:

[WebService(Namespace = http://www.jvr.be/AsmxService)]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

public class AsmxService : WebService

{

    [WebMethod(MessageName = "ProcessOrder")]

    public String ProcessOrder(String xmlRequest)

    {

        // Convert the XML request back to objects

        // Process the order

        Debug.Write("ProcessOrder on ASMX service called.");

        // Return an XML response

        String xmlResponse = "This is a versioned reponse.";

        return xmlResponse;

    }

}

Migrating from ASMX web services to WCF

When migrating to a WCF service, we obviously want the existing client applications to keep working with the service agents, buy Heartz (Medium Dogs) from mexico. Purchase Heartz (Medium Dogs), New applications can use a WCF client proxy for communicating with a new contract of the WCF service. This way we can use the versioning technology of WCF for future releases, purchase Heartz (Medium Dogs). Buy generic Heartz (Medium Dogs), Existing applications can gradually move to a WCF client proxy as well, but at their own pace, Heartz (Medium Dogs) from canadian pharmacy.

The whole setup is to trick the service agents that the ASMX web service is still there while it actually is replaced with a WCF service that provides an extra service contract that mimics the old ASMX web service for backwards compatibility, BUY Heartz (Medium Dogs) ONLINE WITHOUT PRESCRIPTION. Order Heartz (Medium Dogs) no prescription, Let's see how we can do this in code.

First we define a service contract for the old ASMX web service, order Heartz (Medium Dogs) from mexican pharmacy. Rx free Heartz (Medium Dogs),

[ServiceContract(Namespace = http://www.jvr.be/AsmxService)]

public interface IOldAsmxService

{

    [OperationContract(

        Action = http://www.jvr.be/AsmxService/ProcessOrder)]

    String ProcessOrder(String xmlRequest);

}

Notice the namespace provided by the ServiceContract and the action for the OperationContract. This is how the new service contract looks like:

[ServiceContract]

public interface IWcfService

{

    [OperationContract]

    ProcessOrderResponse ProcessOrder(

        ProcessOrderRequest request);

}

Implementing the concrete service class is somewhat straightforward:

[ServiceBehavior(Namespace = http://www.jvr.be/AsmxService)]

public class WcfService : IWcfService, kjøpe Heartz (Medium Dogs) på nett, köpa Heartz (Medium Dogs) online, Buy Heartz (Medium Dogs) ONLINE WITHOUT prescription, IOldAsmxService

{

    public ProcessOrderResponse ProcessOrder(

        ProcessOrderRequest request)

    {

        // Process the order

        Debug.Write("ProcessOrder of IWcfService called.");

        return new ProcessOrderResponse();

    }

    public String ProcessOrder(String xmlRequest)

    {

        // Map XML request to a ProcessOrderRequest 

        // (in a separate mapper class!!)

        // Process the order

        Debug.Write("ProcessOrder of IOldAsmxService called.");

        var response = ProcessOrder(new ProcessOrderRequest());

        // Map ProcessOrderResponse to a XML response 

        // (in a separate mapper class!!)

        return "Some mapped XML reponse";

    }

}

Notice that the service method that supports the contract of the old ASMX web service delegates its call to to the new method. BUY Heartz (Medium Dogs) ONLINE WITHOUT PRESCRIPTION, You can also do this the other way around if you want.

The first step to make this all work is to add a new file with an .asmx extension that contains the following line:

<%@ServiceHost language=c# Debug="true" Service="Jvr.WcfService" %>

The next step is to add the following configuration settings to the web.config file of the WCF service, Heartz (Medium Dogs) price, coupon. Purchase Heartz (Medium Dogs) online,

<system.web>

    <compilation debug="false">

        <buildProviders>

            <remove extension=".asmx"/>
