Regular videos on current .NET from a Microsoft MVP: performance benchmarks, new language and runtime features as they ship, testing, dependency injection, and blunt critiques of widely used libraries. Code-heavy, typically ten to twenty minutes.

How Async/Await Really Works in C#
Traces C# asynchrony from the Begin/End and event-based patterns through Task, ValueTask, and the compiler-generated state machine, with decompiled code showing exactly what await expands into and how ExecutionContext flows.
Concurrency in C# Cookbook, 2nd Edition
Eighty-five recipes for asynchronous, parallel, reactive and dataflow code in C#: async/await patterns, cancellation, progress reporting, TPL Dataflow, System.Reactive, unit testing concurrency, and the deadlocks caused by mixing blocking and asynchronous calls. Async is where C# learners actually get hurt, and this is the only prescriptive, tested treatment of it.
ASP.NET Core in Action, Third Edition
Builds server-side .NET web applications step by step: minimal APIs, Razor Pages, middleware, dependency injection, configuration, Entity Framework Core, authentication, and testing. Targets ASP.NET Core 7; nearly all of it applies to later releases.
C# 12 in a Nutshell: The Definitive Reference
Reference covering the whole language plus core .NET libraries: type system, generics, LINQ internals, spans and memory, async, threading, serialization, and interop. Written for people who already program; this edition targets C# 12 and .NET 8.
Foundational C# with Microsoft
Certification track pairing roughly 35 hours of Microsoft Learn C# modules — variables, control flow, methods, arrays, debugging, exception handling, object-oriented basics — with a freeCodeCamp exam. Browser-based exercises; a free certificate is issued on passing.
C# language documentation
Microsoft's official C# guide: a tour of the language, fundamentals, tutorials, dedicated LINQ and asynchronous programming sections, plus the complete language reference and specification. Revised with every release, currently documenting C# 15. The only C# reference that is guaranteed current with each release, and the single starting point that removes the need to pick among tutorial sites.
