Learn to program C# in a Console environment using Visual Studio. Apply the .NET Framework and object-oriented programming principles to create a C# application. In addition, develop skills in designing and writing C# computer programs using structures, collections and custom exceptions. Develop the skill to test code using unit-testing techniques. Get hands-on practice with applying these programming concepts by creating new code and revising existing code. Study C# programming in a Console environment using Visual Studio.

• C# Programming: 1 or equivalent knowledge

Create a C# console application that will enable user interaction with an application in a Console Window.

• Describe the Common Language Runtime (CLR) and the Base Class Library (BCL) components of the .NET Framework
• Use the command line to compile a .NET application
• Create code to read and display a revised message on the Console Window
• Use the Locals Window in debugging mode to change the value of a local variable

Add a class to an application that implements encapsulation and all types of members including constructors and methods.

• Create and use a class containing static and instance members
• Modify a class to include operator overloading
• Create and use a static class
• Run unit tests against an application

Apply inheritance and polymorphism principles using multiple classes.

• Implement inheritance by adding a class that inherits from another class
• Use polymorphism to print custom information for each derived type
• Convert a class to an abstract class
• Seal a class to prevent inheritance
• Apply Object Class methods

Add a custom exception class to an application that will throw the exception when a business rule is violated and catch the exception on the client side.

• Throw a new instance of an exception object
• Retrieve the contents of the InnerException property of an exception object using a recursive method
• Create and use a custom exception class

Add a service class to an application to store information in a collection, and provide an indexer for the client class to store and retrieve that information.

• Implement an array of a reference type to store and retrieve information
• Implement an indexer to store and retrieve information from a collection
• Implement the List and Dictionary generic collections to store and retrieve information

Implement polymorphism using an interface.

• Create and implicitly implement multiple interfaces
• Apply polymorphism by executing a method through an interface reference
• Create an explicit implementation of an interface
• Implement the IDisposable and IComparable interfaces

Add a struct to an application to manipulate a given string message and test it using unit-testing techniques.

• Create and use a struct
• Create a struct that employs the StringBuilder class to build a string in a specified format
• Create unit tests to test an application as it is being coded
