A key part of developing any application is dividing the solution into logical components.

Exception handling is an important concept and your applications should be designed with exception handling in mind. This module explains how you can implement effective exception handling in your applications, and how you can use exceptions in your methods to elegantly indicate an error condition to the code that calls your methods.

The Microsoft.NET Framework base class library consists of many types that you can use in your applications. However, in all applications, you must also build your own types that implement the logic for your solution.


This module explains how to create your own modules and types and describes the differences between reference types and value types.

After completing this module, students will be able to:


Describe how to control the visibility of type members.

This module introduces inheritance and interfaces in the Microsoft .NET Framework, and how you can use them to simplify complex problems, reduce code duplication, and speed up development.


Inheritance is a key concept in an object-oriented language. You can use inheritance, interfaces, and abstract classes to develop object hierarchies in your code. These object hierarchies can help reduce bugs by defining clear contracts for what a class will expose and by providing default implementations where you can sensibly abstract code into a base type.


Using Inheritance to Define New Reference Types


Defining and Implementing Interfaces


Defining Abstract Classes


Defining an Interface


Implementing an Interface


Creating an Abstract Class


After completing this module, students will be able to:


Use inheritance to define new reference types.


Define and implement interfaces.


Define abstract classes.


All applications use resources. When you build a Microsoft Visual Basic application, resources fall into two broad categories: managed resources that are handled by the common language runtime (CLR) and unmanaged resources that are maintained by the operating system outside the scope of the CLR. A managed resource is typically an object based on a class defined by using a managed language, such as Visual Basic. Examples of unmanaged resources include items implemented outside the Microsoft .NET Framework, such as Component Object Model (COM) components, file handles, database connections, and network connections.


Resource management is important in any applications that you develop. The NET Framework simplifies resource management by automatically reclaiming the resources by a managed object when it is no longer referenced by an application. Managed resources are handled by the .NET Framework garbage collector. However, unmanaged resources are not controlled by the garbage collector; you must take special steps to dispose them properly and prevent them from being held longer than necessary.


Introduction to Garbage Collection


Managing Resources


Implementing the IDisposable Interface


Managing Resources Used by an Object


After completing this module, students will be able to:


Describe how garbage collection works in the .NET Framework.


Manage resources effectively in an application.


Many operators have well-defined behavior for the built-in Visual Basic types, but you can also define operators for your own types. This module describes how to implement operators for your types by using overloading.


Creating and Using Properties


Creating and Using Indexers


Overloading Operators


Defining Properties in an Interface


Implementing Properties in a Class


Using Properties Exposed by a Class


Implementing a Default Property to Access Bits in a Control Register


Using an Indexer Exposed by a Class

After completing this module, students will be able to:


Explain how properties work and use them to encapsulate data.


Describe how to use default properties to provide access to data through an array-like syntax.


Describe how to use operator overloading to define operators for your own types.


This module explains how to decouple an operation from the method that implements it and how to use anonymous methods to implement decoupled operations. This module also explains how to use events to inform consuming applications of a change or notable occurrence in a type.


Declaring and Using Delegates


Using Lambda Expressions


Handling Events


Raising and Handling Events


Using Lambda Expressions to Specify Code


After completing this module, students will be able to:


Describe the purpose of delegates and explain how to use a delegate to decouple an operation from the implementing method.


Explain the purpose of lambda expressions and describe how to use a lambda expression to define an anonymous method.


Explain the purpose of events and describe how to use events to report that something significant has happened in a type that other parts of the application need to be aware of.


The basic collection classes introduce a new problem. Classes that act on other types are often not type-safe. For example, many collection classes frequently use the Object type to store items, and must then be cast or converted back to their original type before they can be used. It is the programmer’s responsibility to ensure that the correct casts or conversions are performed, and it is easy to introduce errors by casting or converting an item to the wrong type. This module introduces generics and how you can use generic classes to maintain type-integrity and avoid issues that are associated with a lack of type safety.

When you develop applications, you often need to store collections of objects. In many circumstances, you can use the collection classes that the Microsoft .NET Framework includes; however, sometimes these collection classes do not provide the functionality that you require. For example, you may need to store objects in a sorted order that is based on a custom sorting algorithm.


This module introduces you to custom collection classes. It also explains how you can develop collection classes that support the language constructs that Visual Basic provides, such as enumeration and collection initialization.


Implementing a Custom Collection Class


Adding an Enumerator to a Custom Collection Class


Implementing the IList(Of TItem) Interface

This module introduces you to Language-Integrated Query (LINQ) queries and explains how you can use them to process data in your Microsoft .NET Framework applications. This module also explains the difference between shared and dynamic LINQ queries, and describes how you can use dynamic LINQ to create highly flexible queries that you build at run time.


Using the LINQ Extension Methods and Query Operators


Building Dynamic LINQ Queries and Expressions


Using the LINQ Query Operators


Building Dynamic LINQ Queries


After completing this module, students will be able to:


Describe how to use the LINQ extension methods and query operators.


Describe how to build dynamic LINQ queries and expressions.


Integration with other technologies is a key feature of the Microsoft.NET Framework. Previous versions of the .NET Framework enabled you to combine components that were developed by using different languages that have compilers that the .NET Framework supports. The .NET Framework 4 now supports integration of components built by using dynamic languages. This enables you to re-use items built by using a wide range of scripting languages that are not easily accessible from Microsoft Visual Basic code.


In addition, previous versions of the .NET Framework have always enabled you to integrate Component Object Model (COM) services and components into your managed applications. The integration did however, require a good understanding of the differences between the way in which the common language runtime (CLR) and the COM environment operated. The new features of Visual Basic 2010 have simplified the way in which you can invoke COM components, so it is easier for you to re-use these items in a Visual Basic application.


This module describes how to integrate code written by using a dynamic language such as Ruby and Python, or technologies such as COM, into a Visual Basic application.


Integrating Visual Basic Code with Ruby and Python


Accessing COM Components from Visual Basic


Integrating Code Written by Using a Dynamic Language into a Visual Basic Application
