A collection of examples of problematic patterns in ASP.NET Core applications with guidance on how to fix them, based on real-world customer issues. It includes general ASP.NET Core and asynchronous programming guidance for writing scalable web services.

Use cases

• learn common async/await pitfalls in ASP.NET Core
• diagnose why my ASP.NET Core app is slow or blocking
• find examples of broken patterns in scalable web services
• learn best practices for writing scalable ASP.NET Core services
• understand sync-over-async deadlocks in .NET
• review guidance before a production performance audit

When to choose

• you build or maintain ASP.NET Core web services and want to avoid common performance pitfalls
• you are debugging blocking, deadlocking, or scalability issues in a .NET web app
• you want curated, real-world-derived guidance on async programming in C#

When to avoid

• you need runnable production code or a library to drop into your project
• you work outside the .NET/ASP.NET Core ecosystem
• you need up-to-date coverage of the latest .NET versions, as the repo is in maintenance mode
