Indicates specialized classes for working with security tokens that are associated with Kerberos tickets. Indicates specialized classes for working with X.509 digital certificates. Note that this namespace provides utility classes for working with the classes in namespace .Security.Cryptography.X509Certificate.X509Certificate2. Specifies generic classes for working with security-oriented properties, such as the creation and expiration time stamp information for a SOAP message. Indicates specialized classes for working with XML signatures, which are an important support technology for digital signatures. Specifies general support classes for working with XML, particularly as it relates to the XML that is generated by the WS- specifications. These classes are used in conjunction with other XML classes in the .NET Framework.

WSE provides programmatic hooks in the specifications that automatically generate the required SOAP elements for you, so you do not have to construct them manually. The WSE API is accessed differently by Web services vs. Web service clients. Let s briefly look at the differences.
Note With Visual Studio 2005, Web services can now be hosted under console applications through
simple configuration entries in the application configuration file. This chapter focuses on Web services that are hosted under IIS, because it is currently a more common implementation scenario for .NET developers.
Web Service Access to the WSE API
Web services can access the SoapContext for either request or response SOAP messages using specialized classes called RequestSoapContext and ResponseSoapContext. These classes provide direct access to SOAP messages, and they support messages that are transported over different protocols, including the HTTP and TCP protocols. Each of the classes provides a static property called Current, which furnishes a reference to the SoapContext class. For request messages, the SoapContext class is accessed using SoapContext requestContext = RequestSoapContext.Current; RequestSoapContext is a class provided by the WebServicesClientProtocol, and Current is a static property that returns the SoapContext class. For response messages, the SoapContext class is accessed using SoapContext responseContext = ResponseSoapContext.Current;
CHAPTER 5 WEB SERVICES ENHANCEMENTS 3.0
Once the client references the SoapContext for the request message, it can reference or assign WS- specifications with the WSE API. For example, if the incoming request message requires digital signing with a certificate, the Web service can inspect the attached digital signatures using SoapContext (as shown previously in Listing 5-4). The Web service can also use SoapContext to modify outgoing response messages. Unlike the service proxy class (described in the next section), the Web service itself does not need to derive from a specialized class in order to access the WSE functionality. However, you need to make sure the WSE support assemblies are correctly registered in the service s web.config file.
Note The SoapContext.Current static class creates a blocking risk because it interacts directly with the
Web service context. For this reason, a Web service wrapper class (that invokes the Web service proxy) should never be created as a singleton; otherwise, multiple calls to the wrapper will result in blocked calls. Here is an example of what not to do:
Public Class webservicewrapper (singleton) { Private webserviceproxy _myProxy; Public void dosomething { _myProxy.DoSomething(); } }
Web Service Client Access to the WSE API
A Web service client interacts with a Web service via a proxy class. WSE provides a new base class for this proxy class to inherit from Microsoft.Web.Services3.WebServicesClientProtocol Without WSE installed, proxy class files inherit from System.Web.Services.Protocols.SoapHttpClientProtocol If WSE 3.0 is installed and a reference is set to Microsoft.Web.Services, two classes will be generated. One class will be derived from SoapHttpClientProtocol and will be named after the service (e.g., MyServiceClass). The second generated class will derive from WebServicesClientProtocol and will be named after the service name, with WSE appended to it (e.g., MyServiceClassWSE). The WebServicesClientProtocol class provides access to the SoapContext class for both request and response messages via the proxy class. Listing 5-5 shows an example of a Web client that is digitally signing a SOAP request message before sending it out to a service. The listing shows how you reference the SoapContext and then use it to assign the digital signature to the SOAP request message.
