Course Description


This thorough and comprehensive course is a practical introduction to programming in C#, utilizing the services provided by .NET. This course emphasizes the C# language. It is current to Visual Studio 2022, .NET 6 and C# 10. Important newer features such as dynamic data types, named and optional arguments, tuples, asynchronous programming keywords, nullable reference types, record types, and top-level statements are covered. Supplements provide a tutorial on Visual Studio 2022, an overview of LINQ, and coverage of unsafe code and pointers in C#.

This course is intended to be fully accessible to programmers who do not already have a strong background in object-oriented programming in C-like languages, such as C++ or Java. It is ideal, for example, for procedural programmers who desire to learn C#.

An important thrust of the course is to teach C# programming from an object-oriented perspective. It is often difficult for programmers trained originally in a procedural language to start “thinking in objects.” This course introduces object-oriented concepts early, and C# is developed in a way that leverages its object orientation. A case study is used to illustrate creating a complete system using C# and .NET. Besides supporting traditional object-oriented features, such as classes, inheritance, and polymorphism, C# introduces several additional features, such as properties, indexers, delegates, events, and interfaces that make C# a compelling language for developing object-oriented and component-based systems. This course provides thorough coverage of all these features.

C# as a language is elegant and powerful. But to utilize its capabilities fully, you need to have a good understanding of how it works with the .NET Framework. The course explores several important interactions between C# and the .NET Framework, and it includes an introduction to major classes for collections, delegates, and events. It includes a succinct introduction to creating GUI programs using Windows Forms. The course concludes with a chapter covering the newer features in the language.

Numerous programming examples and exercises are provided, including the case study. The student will receive a comprehensive set of materials, including course notes and all the programming examples.

Course Length: 5 Days
Course Tuition: $2090 (US)


The student should have programming experience in a high-level language.

.NET Uses & Stats

.NET is Used For:
Windows Applications Business Enterprise Applications Software Development Web Applications
Year Created
In Demand: 
C# along with Java is one of the top languages in demand for employers. 
.Net Library:
C# is integrated with the .Net Library thereby providing access to a vast archive of functionality and support. 
Team Friendly:
Multiple developers can easily work together on a project. 
Compiled Language:
The code that is stored on a public-facing server is in binary form. In other words, if your server gets hacked, the hacker doesn't automatically have access to your source code. 
C# roots are derived from C which means that the structure is transferable to other languages like Java, Objective C, PHP and C++. 

Steep Learning Curve:
For beginners, C# is not the easiest program to start with. 

Windows Application Exclusively:
Any .NET application needs a Windows platform to execute which means that companies using Linux servers would need Windows hosting to run a .Net application. 
Lack of Support for Older .NET:
Many enterprise organizations keep older operating systems because of the many problems that an upgrade can bring to the platform. Microsoft stops supporting older .NET frameworks after a few operating systems upgrades.

Complimentary Skills to have along with .NET

Since the .NET development ecosystem spans a wide array of capabilities and tools, it is difficult for .NET developers to know which .NET development skills and training to pursue in order to increase their marketability — and earning potential.  For that reason, learning supplemental languages such as Java, JavaScript, Python, C/C++, and others is expected in today’s competitive skill-set driven playing field.
