The .NET Foundations course provides a thorough exploration of the .NET architecture and runtime internals for C# developers. This 14-hour course covers the Common Language Runtime (CLR), .NET Class Library, NuGet package management, metadata, reflection, I/O operations, delegates, events, threading, and the Task Parallel Library (TPL). Duration: 14 hours — €797. Esamatic srl, a Microsoft Learning Partner in Milan, delivers this course with Microsoft Certified Trainers.

.NET Architecture: CLR internals, managed execution, JIT compilation, and garbage collection
Class Library & NuGet: leveraging the Base Class Library and managing dependencies with NuGet
Metadata & Reflection: assembly metadata inspection and runtime type discovery
Delegates & Events: callback mechanisms, event-driven programming, and lambda expressions
Threading & TPL: multithreading, Task Parallel Library, async/await patterns, and concurrent collections

Course Overview: .NET Foundations

The .NET platform is the backbone of modern Microsoft development, powering everything from web APIs to desktop applications. Understanding the runtime internals — how the CLR manages memory, how assemblies are loaded, how the type system works — is what separates productive C# developers from expert .NET engineers. This course bridges that gap with deep coverage of the platform’s core mechanisms.

Learning Objectives

Understand .NET architecture — explore the CLR, managed code execution, JIT compilation, garbage collection, and the assembly loading process
Leverage the Class Library and NuGet — use Base Class Library types effectively and manage packages and dependencies with NuGet
Apply metadata and reflection — inspect assemblies at runtime, discover types dynamically, and generate code using reflection emit
Master asynchronous programming — implement delegates, events, threading, TPL tasks, and async/await for responsive applications

Who Should Attend

This course is designed for C# developers who want to deepen their understanding of the .NET platform, software engineers transitioning to .NET, and junior developers looking to build a strong foundation in .NET internals.

Career Benefits

Deep .NET platform knowledge is essential for senior development roles. Understanding CLR internals, async programming, and reflection distinguishes senior .NET developers, software architects, and technical leads in the job market.

Prerequisites

Working knowledge of C# programming fundamentals
Experience building basic .NET applications
Understanding of object-oriented programming concepts

Frequently Asked Questions

Is this course about .NET 6 or .NET Framework?

This course covers the modern .NET platform (.NET 6+). The core concepts (CLR, GC, threading) apply across versions, but examples and tooling use the latest .NET.

Do I need to know C# before taking this course?

Yes, working knowledge of C# is required. This course focuses on platform internals and advanced features, not language basics.

Will this course help me with performance optimization?

Yes, understanding CLR internals, garbage collection, and the TPL is fundamental to writing performant .NET applications and diagnosing performance issues.
