Anatomy of a modern ASP.NET web application
Good architecture isn't an end in itself - it shows in how easily a team moves with it: today and in two years. This eBook revisits modern web-development approaches that everyday work often forgets. Food for thought, not dogma.
- Use dependency injection & lifetimes correctly - from the composition root to a unit of work per request.
- Understand the middleware pipeline: order, rate limiting and custom middleware - including our interactive Middleware Designer.
- Test web APIs like a real consumer - with WebApplicationFactory, Testcontainers and honest TDD.

WebApplicationFactory & Testcontainers
We build and maintain web APIs - for many years.
We're .NET experts from Switzerland, including a Microsoft MVP and open-source contributors. From advising CTOs on architecture to running .NET workshops: we love code - and even more, software that matters.
Dependency Injection
Chapter 4Constructor injection as the norm, DbContext as scoped - and why a singleton must never depend on a scoped service.
Middleware pipeline
Chapter 5CORS → Authentication → Authorization: the ordering invariants - plus an interactive designer to try it out.
Testing
Chapter 6Test web APIs as a real consumer: WebApplicationFactory in memory, Testcontainers for the real database, honest TDD.
Interactive Middleware Designer
Compose your ASP.NET middleware pipeline visually - with warnings for problematic ordering and generated C# code.
An eBook doesn't replace a conversation about your specific architecture. But it shows the principles we build by - and where decisions pay off early.
