How to use

Setup - Add configuration in startup

public void ConfigureServices(IServiceCollection services)
    // Add framework services etc.
    var domainAssembly = typeof(GenerateInvoiceHandler).GetTypeInfo().Assembly;
    // Add MediatR
    services.AddMediatR(cfg => cfg.RegisterServicesFromAssembly(domainAssembly));

    //Add FluentValidation
    services.AddFluentValidation(new[] {domainAssembly});
    //Add other stuffs


Implement validator for your IRequest objects. Validation will be executed before handling IRequestHandler.

public class GenerateInvoiceValidator : AbstractValidator<GenerateInvoiceRequest>
    public GenerateInvoiceValidator()
        RuleFor(x => x.Month).LowerThan(13);
        // etc.

public class GenerateInvoiceRequest : IRequest
    public int Month { get; set; }
public class GenerateInvoiceRequestHandler : IRequestHandler<GenerateInvoiceRequest>
    public async Task Handle(GenerateInvoiceRequest request, CancellationToken cancellationToken)
        // request data has been validated
