.NET is a central part of my work and closely connected to Azure, Altinn and systems that must keep working over time. I use this area to collect the sources I would start with when something needs to be learned, verified or properly understood.
Official documentation and source code come first. Content creators are a valuable supplement: they provide context, demonstrate ways of working and make difficult topics more accessible, but claims should still be checked against primary sources.
Foundations and reference
Start with the sources that describe the platform, language and APIs precisely.
Microsoft Learn
.NET documentation
The main entry point to guides, concepts, tooling, languages and application models.
Open source ↗Microsoft LearnC# documentation
Language reference, fundamentals, new language features and programming guides.
Open source ↗API reference.NET API Browser
Searchable reference for namespaces, types and members across .NET versions.
Open source ↗.NETSupport policy
The authoritative overview of active releases, LTS/STS and end-of-support dates.
Open source ↗Build applications
The central entry points for web, APIs, data, distributed applications and packages.
Microsoft Learn

Open source ↗Conference.NET Conf
The annual free conference with sessions from both product teams and the community.
Open source ↗Community
People and communities I recommend
A personal selection, not a ranking. Some go deep into the runtime and frameworks; others excel at architecture, practical code or teaching.
ASP.NET Core · Aspire · performance
David Fowler
Exceptionally close to the implementation of modern .NET. His GitHub profile is a strong source of code, prototypes and concrete advice on high-performance and distributed systems.
Runtime · concurrency · performance
Stephen Toub
The most thorough explanations of performance, asynchrony and changes to the runtime and base libraries.
ASP.NET Core · hosting · internals
Andrew Lock
Detailed, precise articles on how ASP.NET Core, configuration, dependency injection and the toolchain actually work.
.NET internals · HTTP · observability
Steve Gordon
Practical deep dives into the framework, performance, networking and production-oriented .NET code.
C# · language semantics · precision
Jon Skeet
Unusually precise explanations of C# and difficult language details—an important source when the simple answer is not enough.
EF Core · data · DDD
Julie Lerman
Decades of experience explaining data access, Entity Framework and domain-driven design in practical terms.
Modern C# · testing · concise video
Nick Chapsas
Frequent, concise videos about language features, libraries, testing, performance and modern .NET practices.
Architecture · DDD · APIs
Milan Jovanović
Practical content about modular monoliths, Clean Architecture, DDD, messaging and robust APIs.
Teaching · C# · application development
Tim Corey
Calm, thorough walkthroughs that are particularly useful when you want to see the complete workflow rather than an isolated code trick.
.NET MAUI · tooling · community
James Montemagno
A strong teacher of .NET tooling, cross-platform development, GitHub and product news from across the ecosystem.
A learning sequence that holds up
Language and runtime
Understand C#, the type system, memory management, async/await and how the runtime executes code.
The application model
Learn ASP.NET Core, dependency injection, configuration, logging, HTTP and data access as a connected system.
Production qualities
Move on to security, observability, testing, performance, failure handling and distributed systems.
Primary sources
Use documentation, release notes, issues and source code to verify claims and understand the trade-offs.
