## From README

ABP Core Conventions Documentation: https://abp.io/docs/latest API Reference: https://abp.io/docs/api/ Key Rules Use IClock / Clock.Now instead of DateTime.Now / DateTime.UtcNow Use ITransientDependency / ISingletonDependency instead of AddScoped/AddTransient/AddSingleton Use IRepository instead of injecting DbContext directly Check base class properties (Clock, CurrentUser, GuidGenerator, L) before injecting services Use BusinessException with namespaced error codes for domain rule violations Module System Every ABP application/module has a module class that configures services: Note: Middleware configuration (OnApplicationInitialization) should only be done in the final host application, not in reusable modules.
