Module 1: Review of C# Syntax & New Features 

The .Net (Core) provides a comprehensive development platform that you can use to build, deploy, and manage applications and services. By using the .Net, you can create visually compelling applications, enable seamless communication across technology boundaries, and provide support for a wide range of business processes.

Module 2: Creating Methods, Handling Exceptions, and Monitoring Applications 

Applications often consist of logical units of functionality that perform specific functions, such as providing access to data or triggering some logical processing. C# is an object-orientated language and uses the concept of methods to encapsulate logical units of functionality. A method can be as simple or as complex as you like. In this module, you will learn how to create and use methods and how to handle exceptions. You will also learn how to use logging and tracing to record the details of any exceptions that occur. 

After completing this module, students will be able to: 

• Create and invoke methods. 
• Create overloaded methods and use optional parameters. 
• Handle exceptions. 
• Monitor applications by using logging, tracing, and profiling 

Lessons

• Creating Overloaded Methods and Using Optional and Output Parameters 
• Handling Exceptions 
• Using log & trace 

Module 3: Basic types and constructs of C# 

To create effective applications, you must first learn some basic C# constructs. You need to know how to create simple structures to represent the data items you are working with. You need to know how to organize these structures into collections, so that you can add items, retrieve items, and iterate over your items. Finally, you need to know how to subscribe to events so that you can respond to the actions of your users. 

In this module, you will learn how to create and use structs and enums, organize data into collections, and create and subscribe to events. 

After completing this module, students will be able to: 

• Create and use structs and enums. 
• Use collection classes to organize data. 
• Create and subscribe to events.
