Microsoft Course 2557 - Building COM+ Applications Using Microsoft .NET Enterprise Services — A 5-Day Course

 Open Public Course Closed In-House Course

Course Synopsis

This five-day, instructor-led course provides students with the knowledge and skills to effectively build scalable, distributed applications that use Microsoft .NET Enterprise Services and the Microsoft .NET Framework.

Course Objectives

On completion of this course, delegates will be able to:

• Describe the history of server-based applications and describe the COM+ runtime architecture.
• Use attributes to configure an assembly as a COM+ application and create components that use just-in-time (JIT) activation and are synchronized.
• Create data access components that use Microsoft ADO.NET to retrieve or update data in a database.
• Create transactional components.
• Help protect an enterprise application by using COM+ services role-based security.
• Manage state in JIT activated components.
• Create compensating resource managers to enable transactional support for resources lacking a resource manager.
• Use loosely coupled events to send notifications to other applications.
• Create queued components.
• Debug COM+ applications and describe common application-failure scenarios and how to solve these failures.
• Create scripts for managing deployment and administration.
• Use the enhancements provided by COM+ version 1.5 to improve the scalability, availability, and manageability of COM+ applications and use COM+ features such as services without components (SWCs), bring your own transaction (BYOT), and Phase Zero notification in applications.

Intended Audience

This course is intended for:

• Departmental developers who currently build client/server applications and large-scale solutions for departments inside a business.
• Consultants who work with developers to build client/server applications and large-scale solutions for businesses.
• Web developers who build Web-based applications requiring significant infrastructure support such as transactions, security, and pooling of resources.
• Line-of-business (LOB) application developers.

Outline Course Contents

Introduction to COM+ Services

This module covers the evolution of applications from monolithic applications to client/server applications to component-based applications and the supporting application infrastructure that COM+ services provides. The module also covers the COM+ runtime architecture and how it uses surrogates, context, and interception to provide services to components.

• History of Server-Based Applications
• The COM+ Runtime Architecture

Configuring Just-in-Time Activation and Synchronization

This module describes the attributes that you can assign to components and how to write a serviced component. This module also describes how to access the object context from within code, JIT activation, synchronization, the relationship between synchronization and JIT activation, and how you can set JIT activation and synchronization for a component.

• The .NET Enterprise Services Programming Model
• JIT Activation
• Synchronization

Using ADO.NET to Work With Data

This module describes how to run a query and retrieve a result set by using ADO.NET. The module also covers how to pass parameters to a stored procedure, create typed DataSet objects, and use construction strings to specify connection information to establish a connection to a data source.

• The ADO.NET Architecture
• Accessing a SQL Server Database

Transaction Services

This module describes transaction processing, how it is implemented in .NET Enterprise Services, and how you add attributes to code to enable transaction processing.

• Introduction to Transaction Processing
• .NET Enterprise Services Transactions

Securing Enterprise Applications

This module explains how to implement COM+ role-based security in serviced components by using .NET Enterprise Services.

• Introduction to Application Security
• Implementing COM+ Role-Based Security
• Authentication and Impersonation

State Management

This module describes how to manage state in .NET Enterprise Services. It explains how to use the shared property manager (SPM) to store state, use ASP.NET applications to store application and session state, and use ASP.NET caching.

• Introduction to State Management
• Using the Shared Property Manager
• Using ASP.NET to Store State

Compensating Resource Managers

This module describes the architecture of compensating resource managers (CRMs) and how to implement CRMs.

• Introduction to Compensating Resource Managers
• Implementing Compensating Resource Managers

Loosely Coupled Events

This module describes the architecture of Loosely Coupled Events (LCEs) and the LCE system. This module also describes how to configure and implement publishers, subscribers, and event classes.

• Introduction to Loosely Coupled Events
• COM+ Events
• Using Loosely Coupled Events

Queued Components

• Introduction to Queuing
• Developing Queued Components
• Queued Components and Transactions

Debugging COM+ Applications

In this module, you will learn how to debug applications that use .NET Enterprise Services.

• Debugging Tools
• Common Debugging Scenarios

Deploying and Administering COM+ Applications

This module introduces the COMAdmin objects and additional techniques and tools for deploying and administering COM+ applications. It describes the advantages and drawbacks of each technique so that students can select the one most appropriate for your application.

• Deploying a COM+ Application Built Using .NET Enterprise Services

COM+ 1.5 Enhancements

This module explains how to use new COM+ version 1.5 features that help you manage, scale, and maximize the uptime of your COM+ application more efficiently. The module also explains how to use .NET Enterprise Services without having to implement serviced components.

• Scalability and Availability Enhancements
• Manageability Enhancements
• Other COM+ Features
