Simple .NET MediatR base Query, Command, Event and Validation.

Event Queue and Validation behaviors written on C#.

Main Features:

• Queries, and QueryHandlers.

  Implemented base patterns to work with Queries. The Queries used just to get any data.

• Commands and CommandHandlers.

  Implemented base patterns to work with Commands. The Commands used to modify entities.

• Events, EventHandlers, EventWriter and EventReader.

  Implemented base patterns to crate Events, approach how to write a new Events from the Commands, consuming patterns and behavior to handle it. The main idea is to do some actions after the Commands have to be finished, to avoid cases when one Command call another one.

• Filters.

  Here included filter behavior based on RequestFilter and ResultFilter. The RequestFilter allow to filter Queries and Commands requests before their execution. The ResultFilter allow to filter Queries and Commands results after their execution.

• Validation.

  Here included validation behavior based on FluentValidation, that allow to validate Queries and Command before their execution.
