Blueprint .NET API Patterns

Feature folder structure

Queries live in Api/Features/{Feature}/, commands and domain logic in Domain/{Feature}/Commands/:

Api/Features/Products/
  GetProducts.cs              // list query — static class
  GetProductDetails.cs        // detail query — static class
  IsProductCodeUnique.cs      // custom query — static class
  ProductsController.cs       // thin — only mediator.Send()

Domain/Products/Commands/
  ProductCreateOrUpdate.cs              // static class: Command, Result, Validator
  ProductCreateOrUpdateCommandHandler.cs // separate file
  RemoveProduct.cs
