Course Summary
In this course, you'll learn about the services offered
by Enterprise Services and when to use them. You'll see
how to use asynchronous programming and threading in your
applications, and how to use transactions to prevent data
corruption while reducing coding effort. The course shows
you how to use MSMQ and Queued Components to create client-server
applications that work even when the client and server
are disconnected. You'll also learn how to manage scarce
resources with the Dispose pattern and object lifetime
options such as pooling and just in time activation.
This course is focused on the "back end" part of enterprise
programming, not the user interface. The sample applications
are Windows applications, to keep the pre-requisites to
a minimum. You'll be able to use these same concepts as
the back end to a web (ASP.NET) application as well.

What You Can Expect
At the end of this course, delegates will be able to:
- Identify the Enterprise Services that may be useful for
a particular application.
- Use asynchronous programming and threading to speed the
response time of your applications.
- Use COM components from a .NET application and .NET objects
from a COM application.
- Add transaction support to an enterprise application.
- Use Message Queuing and Queued Components to write distributed
applications that are more robust and available.
- Manage scarce resources and object lifetimes.
Who Should Take This Course
Developers that need to build distributed enterprise applications.
Recommended Prerequisites
In order to understand some of the problems and dilemmas
that present to a developer creating an enterprise application,
you should be an experienced programmer (in any language).
The course uses Visual Basic .NET, so you should already
be comfortable with the .NET Framework and coding in Visual
Basic .NET, including how to compile and run applications
in Visual Studio .NET.
Training Style
Instructor led with hands on labs.
