This code shows how we get from ASP.NET 5 to ASP.NET 9 with minimal APIs. Throughout the live demo, we upgrade small pieces of an ASP.NET 5 app until we leverage these brand-new ASP.NET and C# 10 and 11 features:
- File-scoped namespaces
- Global using directives
- Automatic global usings
- Top-level statements
- async Main
- Minimal APIs
- Parameter and Dependency Injection
- Integration testing improvements
- Default constructors
