Building COM+ Applications Using Microsoft .NET Enterprise Services

Target Audience
The goal of this course is to enable developers to effectively build scalable, distributed applications that use Microsoft .NET Enterprise Services and the .NET Framework

Pre-Requisites
Before attending this course, students must be able to:Experience building assemblies by using Microsoft Visual Basic .NET or Microsoft Visual C#Experience handling database transactions in program codeStudents can meet these prerequisites by takingCourse 2349, Programming with the Microsoft .NET Framework(Microsoft Visual C# .NET)

Purpose
After completing this course, students will be able to state the need for using Enterprise Services and list the elements of an enterprise-wide application and the classes of the EnterpriseServices namespace and the .NET Framework that help program these elements; describe the Enterprise Services architecture and programming model and create Just-in-Time (JIT) activated and synchronized components; create data access components that use ADO.NET to retrieve or update data in a database; create transactional components; secure an enterprise application by using Enterprise Services role-based security and .NET role-based security; manage state in JIT activated components; create Compensating Resource Managers (CRMs) to enable transactional support for resources lacking a resource manager; use loosely coupled events (LCEs) to send notifications, both filtered and unfiltered; create transactional message queues and queued components; debug Enterprise Services applications and describe common application failure scenarios and how to solve these failures; create Enterprise Services scripts for managing deployment and administration; describe some interoperability scenarios for enterprise applications and how to design and program for these scenarios
