## Original MediatR
[](https://www.nuget.org/packages/mediatr)
[](https://www.nuget.org/packages/mediatr)
[](https://myget.org/gallery/mediatr-ci)
Simple mediator implementation in .NET
In-process messaging with no dependencies.
Supports request/response, commands, queries, notifications and events, synchronous and async with intelligent dispatching via C# generic variance.
Examples in the [wiki](https://github.com/jbogard/MediatR/wiki).
### Installing MediatR
You should install [MediatR with NuGet](https://www.nuget.org/packages/MediatR):
Install-Package MediatR
Or via the .NET Core command line interface:
dotnet add package MediatR
Either commands, from Package Manager Console or .NET Core CLI, will download and install MediatR and all required dependencies.
### Using Contracts-Only Package
To reference only the contracts for MediatR, which includes:
- `IRequest` (including generic variants)
- `INotification`
- `IStreamRequest`
Add a package reference to [MediatR.Contracts](https://www.nuget.org/packages/MediatR.Contracts)
This package is useful in scenarios where your MediatR contracts are in a separate assembly/project from handlers. Example scenarios include:
- API contracts
- GRPC contracts
- Blazor
### Registering with `IServiceCollection`
MediatR supports `Microsoft.Extensions.DependencyInjection.Abstractions` directly. To register various MediatR services and handlers:
```
services.AddMediatR(cfg => cfg.RegisterServicesFromAssemblyContaining());
```
or with an assembly:
```
services.AddMediatR(cfg => cfg.RegisterServicesFromAssembly(typeof(Startup).Assembly));
```
This registers:
- `IMediator` as transient
- `ISender` as transient
- `IPublisher` as transient
- `IRequestHandler<,>` concrete implementations as transient
- `IRequestHandler<>` concrete implementations as transient
- `INotificationHandler<>` concrete implementations as transient
- `IStreamRequestHandler<>` concrete implementations as transient
- `IRequestExceptionHandler<,,>` concrete implementations as transient
- `IRequestExceptionAction<,>)` concrete implementations as transient
This also registers open generic implementations for:
- `INotificationHandler<>`
- `IRequestExceptionHandler<,,>`
- `IRequestExceptionAction<,>`
To register behaviors, stream behaviors, pre/post processors:
```csharp
services.AddMediatR(cfg => {
cfg.RegisterServicesFromAssembly(typeof(Startup).Assembly);
cfg.AddBehavior();
cfg.AddStreamBehavior();
cfg.AddRequestPreProcessor();
cfg.AddRequestPostProcessor();
cfg.AddOpenBehavior(typeof(GenericBehavior<,>));
});
```
With additional methods for open generics and overloads for explicit service types.
