******************************
Module 1, “Overview of the Microsoft .NET Framework,” defines terminology
specific to the Microsoft .NET Framework and describes its key features and
benefits. This module also discusses the namespaces taught in this course.
There will be minimal lecture and no lab. After completing this module, you
will be able to list the major elements of the .NET Framework.
Module 2, “Introduction to a Managed Execution Environment,” introduces the
concept of managed execution and shows developers how to quickly build
applications that take advantage of the new .NET Framework common
language runtime environment. After completing this module, you will be able
to explain the main concepts behind the common language runtime and use the
features of the .NET Framework to create a simple application.
Module 3, “Working with Components,” discusses how to create a small,
componentized application where modules can easily be written in either
Microsoft Visual Basic or C#. The steps necessary to construct, compile, and
run each program are covered in detail. This module also explains how to build
the client application by using the Windows Forms library and Microsoft
ASP .NET Web Forms. After completing this module, you will be able to create
and use components in Windows Forms-based and ASP .NET-based
applications.
Module 4, “Deployment and Versioning,” explains how to use deployment and
versioning features of the .NET Framework common language runtime to build
and deploy applications that are fully managed and protected. After completing
this module, you will be able to use the deployment and versioning features of

the .NET Framework common language runtime to deploy multiple versions of
a component.
Topic Objective

cover...
Briefly describe each
module.

As you describe each
module, acknowledge any
information that will meet
the student expectations
that you recorded earlier.
Introduction 5


Module 5, “Common Type System,” introduces the Common Type System.
The module discusses how to differentiate between value types and reference
types and examines how classes, interfaces, properties, methods, events, and
values are represented in the .NET Framework. After completing this module,
you will be able to create, use, and extend types by understanding the Common
Type System architecture.
Module 6, “Working with Types,” discusses the use of attributes to control
visibility and inheritance on types and explains how to work with various type
operations, such as boxing and unboxing, and type operators. In addition, this
module discusses how to build an interface that supports methods and

properties and how to make interface designs more efficient. Finally, this
module highlights features that are designed to help you work with unmanaged
types, such as Component Object Model (COM) types. After completing this
module, you will be able to create classes and interfaces that are functionally
efficient and appropriate for given programming scenarios.

Module 7, “Strings, Arrays, and Collections,” describes some of the key classes
in the .NET Framework class library. This module explains how to work with

strings, arrays, collections, and enumerators. After completing this module, you
will be able to use the .NET framework class library to efficiently create and
manage strings, arrays, collections, and enumerators.
Module 8, “Delegates and Events,” explains how the .NET Framework uses
delegates in callback and event-handling scenarios. After completing this
module, you will be able to use delegates and events to have an event sender
object signal the occurrence of an “action” to an event receiver object.
Module 9, “Memory and Resource Management,” discusses how the .NET
Framework automatically handles the allocation and release of an object’s
memory resources through garbage collection. After completing this module,
you will be able to describe and control how memory and other resources are
managed in the .NET Framework.
Module 10, “Data Streams and Files,” introduces the System.IO namespace
and discusses the types that it contains that allow synchronous and
asynchronous reading from and writing to data streams and files. This module
discusses synchronous operations only, as asynchronous operations are beyond
the scope of this course. After completing this module, you will be able to read
from and write to data streams and files.
Module 11, “Internet Access,” discusses the use of the System.Net classes to
communicate with other applications by using common protocols, such as
HTTP, Transmission Control Protocol (TCP), User Datagram Protocol (UDP),
and Socket Internet protocols. After completing this module, you will be able to
use the basic request/response model to send and receive data over the Internet.
Introduction 7


Module 12, “Serialization,” explains how to use serialization to convert a graph
of objects into a linear sequence of bytes, which can then be sent to a remote
computer and deserialized, thereby making a clone in the remote memory of the
original graph of objects. After completing this module, you will be able to

serialize and deserialize an object graph.
Module 13, “Remoting and Web Services,” explains how .NET Remoting
supports communication between objects in different application domains, in
different processes, and on different computers. The module describes how the
common language runtime remoting infrastructure provides a rich set of classes
that enable you to ignore most of the complexities of deploying and managing
remote objects. After completing this module, you will be able to create
distributed applications by means of Web Services and Object Remoting.
