C# and .NET Foundations
Rev. 10.0
.NET Training Overview
This five-day course is designed for the experienced programmer to help you quickly come up to speed on the essentials of the C# language and.NET. It is current to Visual Studio 2026 and .NET 10.
Course examples require Microsoft Visual Studio 2026 and Windows 10 or higher. Window 11 is recommended. The free Visual Studio Community 2026 can be used. See the .NET Essentials course Setup Guide for details.
Microsoft .NET is a programming technology that greatly simplifies application development, both for traditional, proprietary applications and for web-based applications and services. The original .NET was a complete restructuring of Microsoft’s whole system infrastructure and represented a major learning challenge for programmers developing applications on Microsoft platforms. Part of .NET included a major new object-oriented programming language, C#. But learning the new programming language is only part of the challenge. The much greater challenge is learning the .NET Class Library and its many capabilities.
A major new restructuring of the .NET platform, .NET Core is cross-platform, open source, and modular designed for creating modern web applications and services, libraries and console applications. It is available on Windows, Mac and Linux. .NET now is a family of frameworks, including both the classical .NET available on Windows and the new .NET Core package-based frameworks that are cross-platform. This course is designed to run on .NET 10.0, which is an LTS (Long Term Support) version of .NET Core.
The first module of the course covers the C# language and core features of C# and .NET, including delegates and events and an introduction to Windows Forms. The second module focuses on core portions of the .NET Class Library that are common across many application areas. It starts with an introduction to the architecture and key concepts of .NET. The course then discusses class libraries, packages, metapackages and frameworks. The following chapters discuss important topics in the .NET programming model, including metadata and reflection, I/O and serialization, memory management, processes and threads. The course concludes with a chapter on threading, which includes an introduction to the Task Parallel Library (TPL).
The course is provided as a combination of two courses, which can also be ordered separately:
The course is hands-on, with many programming examples. The goal is to equip you with the foundations of this important technology from Microsoft. The student will receive a comprehensive set of materials, including course notes and all the programming examples.
