C# – Beyond the Fundamentals
Take your C# further with LINQ, generics, dependency injection, memory management, unit testing and TDD.
This workshop continues from C# Introduction. It covers more advanced C#: LINQ, delegates and lambdas, generics, dependency injection and memory management. The last part is about unit testing and test-driven development (TDD) in .NET: testing libraries, running and debugging tests, asserts, mocking and more advanced tests.
The workshop mixes presentations, demonstrations and hands-on exercises. It is up to date with C# 14, .NET 10 and Visual Studio 2026.

Software developers with at least three months of practical experience with C# and .NET who want to take their skills further.
