Full Changelog: jbogard/MediatR@v12.0.1...v12.1.0

This release removes all scanning around behaviors, stream behaviors, and pre/post processors. That proved too problematic so you MUST register each of these explicitly with the appropriate registration methods inside AddMediatR. This also ensures that the order of behaviors and pre/post processors reflects the explicit order of registration. With the scanning approach, you couldn't control the order.

Full Changelog: jbogard/MediatR@v10.0.1...v11.0.0
Migration Guide: https://github.com/jbogard/MediatR/wiki/Migration-Guide-10.x-to-11.0

v10.0.1: 10.0.1

This is a patch release to support the latest Contracts package, which changed its targets to netstandard2.0 and net461.

Although MediatR supports only netstandard2.1 and above, it should not force the consumers of the contracts as such.

v10.0.0: 10.0.0

This release adds support for IAsyncEnumerable<T>. A new request type, IStreamRequest<T> represents a request to create a stream, with a new handler type IStreamRequestHandler<TRequest, TResponse> to handle. An example:

public class StreamPing : IStreamRequest<Pong>
{
    public string? Message { get; init; }
}

public class PingStreamHandler : IStreamRequestHandler<StreamPing, Pong>
{
    public async IAsyncEnumerable<Pong> Handle(StreamPing request, 
        [EnumeratorCancellation] CancellationToken cancellationToken)
    {
        yield return await Task.Run(() => new Pong { Message = request.Message + " Pang" }, cancellationToken);
    }
}

Where the work inside of the handler would likely be calling some other streaming API, such as gRPC, EF Core streaming support, Dapper streaming etc.

There are also separate behaviors, with IStreamPipelineBehavior that are separate from the normal IPipelineBehavior.

With the addition of IAsyncEnumerable, this release now targets netstandard2.1 exclusively.

There are some breaking API changes, called out in the 10.0 migration guide.
