Planning for Minimal APIs in .NET 7

[DamianEdwards]

Super early list of potential areas to investigate in .NET 7:

• More OpenAPI
  • describe schemas, either from binders or metadata
  • query/header/path params
  • more automatic descriptions (less need to use manual metadata)
  • easier authn/z configuration with Swagger UI light-up
• More inferred parameter binding
  • Form & File binding
  • etc.
• Extensible parameter binding
• Extensible Result processing, e.g. delayed execution, shortcutting
• Validation
• Hot Reload, e.g. top-level statements, modifying route mappings, DI, etc.
• Composition, e.g.
  • Route grouping
  • Route handler filters
• 3rd-party extensibility
  • nSwag
  • OData
  • Microsoft....ApiVersioning
• Developer experience
  • Route debugging tool/features
  • Analyzers
  • API versioning
• Trimming and AoT
• Performance
• Problem Details everything
  • DeveloperExceptionPage
  • Middleware/ExceptionHandler
  • Something else?
• Anti-forgery support (XSRF), e.g. via a middleware
• Teach MVC to do more stuff like Minimal APIs, e.g. auto service resolution
• Expanding the minimalistic philosophy to other areas of ASP.NET Core
  • CORS
  • Authn/z
  • gRPC, SignalR, Orleans
• Razor support (e.g. Results.Page())

Bedrock? Just curious.

Expanding the minimalistic philosophy to other areas of ASP.NET Core

Would introducing minimal APIs for generic hosts and worker services make sense?

Please keep asp.net core 7 runnable on .net 6 LTS runtime.

They ship together so that won't happen
