Outline

Unit 1: Building and Consuming a Simple XML Web Service

This unit describes how you can create a simple Web service and client application by using the .NET Framework. It also explains how you can configure client proxies, and debug and deploy Web services.

Lessons

• Technical Context of Web Services
• Components of Web Service Technology

After completing this unit, students will be able to:

• Explain the technical context for Web services.
• Understand key components of Web service technology.
• Create a Web service and client.
• Configure a Web service client and proxy.
• Deploy and use a Web service.
• Debug a Web service.
• Determine Web service connectivity.

Unit 2: Configuring and Customizing a Web Service

This unit introduces a number of important configuration and customisation options for Web services. It describes how to control the way in which complex parameters to Web methods are serialized. This unit also shows how to use configuration files to control the way in which a Web service operates.

Lessons

• XML Serialization
• How to Use Complex Data Types in Web Services
• How to Use Attributes to Control Serialization
• How to Use Service Configuration Attributes
• Configuration Files

After completing this unit, students will be able to:

• Explain XML serialization of user-defined classes.
• Pass complex data types between a Web service and a client.
• Configure XML serialization.
• Configure SOAP formatting options.
• Configure the namespace and binding for a Web service.
• Configure a Web service by using the Web.config file.

Unit 3: Calling Web Methods Asynchronously

This unit explains how to call a Web method asynchronously. It describes how to improve the responsiveness of client applications by avoiding the need to wait for Web methods to complete execution before continuing processing. This unit covers the different options available for calling Web methods asynchronously and it describes how to create one-way methods.

Lessons

• The Need for Asynchronous Calls
• Options for Making Asynchronous Calls
• One-Way Methods

After completing this unit, students will be able to:

• Explain why asynchronous calls are needed by Web service clients.
• Create and invoke one-way methods.
• Call methods in a Web service asynchronously.

Unit 4: Building a Remoting Client and Server

This unit describes key remoting concepts, and shows how to create a remoting server and client. This unit describes how to use remoting to call methods in remote objects, and how to pass data across remoting boundaries. This unit also shows how to configure and deploy remoting applications.

Lessons

• Technical Context of Remoting
• Remoting Servers and Clients
• Important Components of Remoting

After completing this unit, students will be able to:

• Describe the technical context of remoting.
• Implement a simple remoting server and client.
• Pass data by value across a remoting boundary.
• Configure remoting channels.
• Use different activation modes.
• Configure a remoting service by using a configuration file.
• Deploy and host remotable types.
• Debug a remotable type.

Unit 5: Creating and Serializing Remotable Types

This unit describes how to transfer complex data values across remoting boundaries, and the issues involved in doing so. It compares and contrasts the marshal by value and marshal by reference mechanisms for accessing remote data. This unit also covers version compatibility issues between clients and servers using different versions of a class, and the special requirements for remoting generic classes.

Lessons

• Marshal by Value
• Marshal by Reference
• Version Compatibility for Remotable Types
• Generic Classes

After completing this unit, students will be able to:

• Describe the differences between marshal by value and marshal by reference.
• Describe the issues surrounding versioning and remoting.
• Use version tolerant serialization.
• Configure a communication channel to use different serialization formatters.
• Create and marshal remotable objects by reference.

Unit 6: Performing Remoting Operations Asynchronously

This unit describes how to call a method asynchronously in the remoting environment. It covers the different techniques you can use and it explains how to raise events in a remoting server and handle them in a client.

Lessons

• Asynchronous Methods
• Calling Remote Methods Asynchronously
• One-Way Methods
• Using Events in Remoting Applications

After completing this unit, students will be able to:

• Call remoting methods asynchronously by using BeginInvoke.
• Implement callbacks.
• Create and call one-way methods.
• Create and fire events in remote services.
• Handle events in a client application.

Unit 7: Managing the Lifetime of Remote Objects

This unit describes the lifetime of remote objects and how you can control them. This unit introduces the concepts of remote object leases and sponsors. This unit shows how to initialise a remote object's lease to a specific period, and how to renew an object's lease when it expires by using a sponsor.

Lessons

• Lifetime Sponsors
• Lease Properties
• Leases and Exception Handling

After completing this unit, students will be able to:

• Initialise the lifetime of a remote object.
