• Add support to register a custom implementation of INotificationPublisher
• Add support for IRequestHandler<> which is required for MediatR version 12.0.0

• Add ServiceProviderWrapper to the container but only if typeof(IServiceProvider) has not been registered yet
• Re-add support for netstandard2.0 to align with MediatR

Features

• Add possibility to register MediatR dependencies as either Transient or Scoped. Transient translates to InstancePerDependency whereas Scoped translates to InstancePerLifetimeScope

Chore

Chore

• Update Autofac to version 5.1.1
• Update sample project dependencies

Breaking changes

• Autofac has been updated to 5.0.0. The release of Autofac contains breaking changes, mostly making the container immutable. You can read more about the changes here.

Breaking changes

• MediatR has been updated to 8.0.0. This major release contains small breaking changes. Check out this post for more information.
• Open types were previously registered with implementing interfaces which can cause handlers two be called twice when a class implements IRequestHandler<,> and INotificationHandler<>. To prevent this from happening, .AsImplementedInterfaces() has been removed from the registration. If you wish to register it like before, use this code after calling the extension method AddMediatR.

var openHandlerTypes = new[]
{
    typeof(IRequestHandler<,>),
    typeof(IRequestExceptionHandler<,,>),
    typeof(IRequestExceptionAction<,>),
    typeof(INotificationHandler<>),
};

foreach (var openHandlerType in openHandlerTypes)
{
    builder.RegisterAssemblyTypes(this.assemblies)
        .AsClosedTypesOf(openHandlerType)
        .AsImplementedInterfaces();
}

• Two extensions that were likely not used have been removed from ContainerBuilderExtensions.

Features

• Support for MediatR version 8.0.0 by registering the new behaviors and open-handlers for handling exceptions. Check out this post for more information.

Bugfixes

• Make sure that MediatRModule does not throw when no custom types are passed into the extension methods, fixes #4

Features

• It is now possible to pass in behaviors that implement IPipelineBehavior<TRequest, TResponse>.

Given sample with two custom behaviors without constraints:

public LoggingBehavior<TRequest, TResponse> : IPipelineBehavior<TRequest, TResponse> 
{
    private readonly ILogger<LoggingBehavior<TRequest, TResponse>> _logger;

    public LoggingBehavior(ILogger<LoggingBehavior<TRequest, TResponse>> logger) 
    {
        _logger = logger;
    }

    public Task<TResponse> Handle(TRequest request, CancellationToken cancellationToken, RequestHandlerDelegate<TResponse> next)
    {
        _logger.LogInformation("Got request at {requestTime} and content", DateTime.UtcNow().ToString("O"), JsonConvert.SerializeObject(request));
        
        return next();
    }
}

public CachingBehavior<TRequest, TResponse> : IPipelineBehavior<TRequest, TResponse> 
{
    private readonly ILogger<CachingBehavior<TRequest, TResponse>> _logger;
    private readonly ICache _cache;

    public CachingBehavior(ILogger<CachingBehavior<TRequest, TResponse>> logger, ICache cache) 
    {
        _logger = logger;
        _cache = cache;
    }

    public async Task<TResponse> Handle(TRequest request, CancellationToken cancellationToken, RequestHandlerDelegate<TResponse> next)
    {
        var key = GenerateKeyFromRequest(request);

        _cache.TryGetValue(key, out var cachedResponse) 
        {
            _logger.LogInformation("{key} found in cache, using cached-value", key);
            return await cachedResponse;
        }

        var response = next();

        _cache.Set(key, response);
        
        return await response;
    }
}

We would register MediatR like that

var containerBuilder = new ContainerBuilder();

// Since there are two default behaviors the execution order would now be the following
// 1. LoggingBehavior<TRequest, TResponse>
// 2. CachingBehavior<TRequest, TResponse>
// 3. RequestPreProcessorBehavior<TRequest, TResponse>
// 4. RequestPostProcessorBehavior<TRequest, TResponse>
containerBuilder.RegisterMediatR(typeof(SomeClassThatIsInSameAssemblyAsMediatRTypes).Assembly, 
    typeof(CachingBehavior<,>), typeof(LoggingBehavior<,>));

Given sample with two custom behaviors with and without constraints:

public LoggingBehavior<TRequest, TResponse> : IPipelineBehavior<TRequest, TResponse> 
{
    private readonly ILogger<LoggingBehavior<TRequest, TResponse>> _logger;

    public LoggingBehavior(ILogger<LoggingBehavior<TRequest, TResponse>> logger) 
    {
        _logger = logger;
    }

    public Task<TResponse> Handle(TRequest request, CancellationToken cancellationToken, RequestHandlerDelegate<TResponse> next)
    {
        _logger.LogInformation("Got request at {requestTime} and content", DateTime.UtcNow().ToString("O"), JsonConvert.SerializeObject(request));
        
        return next();
    }
}

public CachingBehavior<TRequest, TResponse> : IPipelineBehavior<TRequest, TResponse> where TRequest : class, ICacheableRequest<TResponse>
{
    private readonly ILogger<CachingBehavior<TRequest, TResponse>> _logger;
    private readonly ICache _cache;

    public CachingBehavior(ILogger<CachingBehavior<TRequest, TResponse>> logger, ICache cache) 
    {
        _logger = logger;
        _cache = cache;
    }

    public async Task<TResponse> Handle(TRequest request, CancellationToken cancellationToken, RequestHandlerDelegate<TResponse> next)
    {
        var key = GenerateKeyFromRequest(request);

        _cache.TryGetValue(key, out var cachedResponse) 
        {
            _logger.LogInformation("{key} found in cache, using cached-value", key);
            return await cachedResponse;
        }

        var response = next();

        _cache.Set(key, response);
        
        return await response;
    }
}

We would register MediatR like that again

var containerBuilder = new ContainerBuilder();

// Since there are two default behaviors, two custom behaviors and one with a constraint, the execution order would now be the following
// 1. CachingBehavior<TRequest, TResponse>
// 2. LoggingBehavior<TRequest, TResponse>
// 3. RequestPreProcessorBehavior<TRequest, TResponse>
// 4. RequestPostProcessorBehavior<TRequest, TResponse>
containerBuilder.RegisterMediatR(typeof(SomeClassThatIsInSameAssemblyAsMediatRTypes).Assembly, 
    typeof(CachingBehavior<,>), typeof(LoggingBehavior<,>));
