MediatR.Extensions.Microsoft.DependencyInjection
Adds MediatR support to Microsoft's dependency injection container for .NET applications.
What is MediatR.Extensions.Microsoft.DependencyInjection?
MediatR.Extensions.Microsoft.DependencyInjection is a .NET library that integrates the MediatR mediator pattern implementation with Microsoft's dependency injection container. It provides extension methods to automatically register MediatR handlers and related components, simplifying the setup process for applications using the mediator pattern.
.NET developers building applications with clean architecture patterns who want to use MediatR with Microsoft's built-in dependency injection container.
This extension eliminates boilerplate code for registering MediatR components and ensures proper service lifetime management, making it easier to adopt the mediator pattern in ASP.NET Core and other .NET applications.
Overview
MediatR extensions for Microsoft.Extensions.DependencyInjection
Use Cases
Best For
- Setting up MediatR in ASP.NET Core applications
- Implementing clean architecture patterns in .NET projects
- Reducing boilerplate code for dependency injection configuration
- Automating registration of request handlers and pipeline behaviors
- Building maintainable applications with separated concerns
- Integrating mediator pattern with Microsoft's DI container
Not Ideal For
- New projects after the archive date, as the functionality is now integrated into the main MediatR repository.
- Applications using dependency injection containers other than Microsoft's built-in one, such as Autofac or Simple Injector.
- Teams needing manual control over service registration without automatic assembly scanning.
Pros & Cons
Pros
Automatically registers all MediatR handlers, pre/post processors, and pipeline behaviors, eliminating boilerplate code for DI setup as highlighted in the key features.
Provides AddMediatR() extension methods for straightforward integration with Microsoft's DI container, simplifying configuration in just a few lines.
Supports automatic discovery and registration of handlers from specified assemblies, reducing manual work and errors in service registration.
Configures appropriate service lifetimes for MediatR components within the DI container, ensuring correct dependency resolution and performance.
Cons
The project is no longer maintained; functionality has been moved to the main MediatR repository, making this extension obsolete for new development.
Only integrates with Microsoft's built-in dependency injection container, limiting flexibility for projects using other DI frameworks like Autofac or StructureMap.
Automatic assembly scanning may not handle complex registration scenarios or custom handler configurations without additional manual intervention.
