An easy-to-use and ambitious in-process mediator to implement CQS

For a detailed understanding and advanced use cases, please refer to the Wiki.

Features

• Developed with .NET 8.0
• Independent (No external dependencies)
• Reduced use of reflection
• Provides polymorphic dispatch and handling of messages with support for covariance and contravariance
• Core Messaging Types include:
  • ICommand: Command without result
  • ICommand<TResult>: Command with a result
  • IQuery<TResult>: Query
  • IStreamQuery<TResult>: Query yielding IAsyncEnumerable<TResult>
  • IEvent: Event
• Designed for flexibility and extensibility
• Modular architecture: Abstractions and implementations are provided in distinct packages
• Allows ordering of handlers
• Can handle plain messages (class types without specific interface implementations)
• Supports generic messages
• Features both global and individual pre and post handlers. These handlers also support covariance and contravariance
• Events do not necessarily need to inherit from IEvent, accommodating DDD scenarios. This is beneficial for maintaining clean domain events without binding them to any particular library interface.
