The Service method help page can be used to invoke your Web methods but can also be used to inspect sample SOAP messages for both the SOAP 1.1 and 1.2 specifications. The .NET Framework 2.0 provides an attribute mechanism to alter the format ting of your SOAP messages. The System.Web.Services.Protocols namespace includes the SoapDocumentMethodAttribute and SoapRpcMethodAttribute classes, which represent the SoapDocumentMethod and SoapRpcMethod. You can build a Web service that complies with the WS-I Basic Profile by using the WebServiceBinding attribute on your Web service class file. The System.Xml.Serialization namespace contains the XmlSerializer class, which is the underlying transport mechanism for Web services built with the .NET Framework 2.0. The XmlSerializer class can be used to customize SOAP mes sages using the XmlElement attribute. SOAP headers are optional according to the SOAP 1.1 and 1.2 specifications, but if you choose to include them, you can implement a custom class file that inher its from the System.Web.Services.Protocols.SoapHeader namespace. The Web method that implements the custom SOAP header will use the SoapHeader attribute to reference the custom class file. You can further customize your Web services by using a custom SOAP extension class that derives from the System.Web.Services.Protocols.SoapExtension class. This class will be implemented in a class library project that represents the SOAP extension.

Having a primary index improves performance because instead of having to navigate the BLOB structure, the SQL Server query processor can execute lookups on the primary index. Those lookups are executed sequentially based on the primary index key. However, you can achieve further performance gains by declaring secondary indexes that let SQL Server avoid sequential lookups on the primary index. Secondary indexes are built on top of the primary index, so they provide different lookup schemes depending on the secondary index keys. Table 8-9 lists the three types of secondary indexes you can create.

Steve Stein When I originally set out to learn how to program data access applications in the first version of ADO.NET, I struggled to understand the relationships between the many different objects in the System.Data namespace. I later realized that I was trying to understand the more complex DataSet and DataAdapter objects without establishing a foundation of knowledge regarding the underlying objects that the DataSet and DataAdapter are made up of specifically, the Connection, Command, and Parameter objects. A solid understanding of working with these data infrastructure objects allowed me to truly understand the inner workings of the more complex objects that you typically use in most Microsoft Windows applications.
