builder.Services.AddRCommon()
    .WithMediator<MediatRBuilder>(mediator =>
    {
        // Registering abstracted mediator requests
        mediator.AddRequest<CreateLeaveAllocationCommand, BaseCommandResponse, CreateLeaveAllocationCommandHandler>();
        mediator.AddRequest<DeleteLeaveAllocationCommand, DeleteLeaveAllocationCommandHandler>();
        mediator.AddRequest<UpdateLeaveAllocationCommand, UpdateLeaveAllocationCommandHandler>();
        mediator.AddRequest<GetLeaveAllocationDetailRequest, LeaveAllocationDto, GetLeaveAllocationDetailRequestHandler>();
        mediator.AddRequest<GetLeaveAllocationListRequest, List<LeaveAllocationDto>, GetLeaveAllocationListRequestHandler>();
        
        // Conventional dependency injection w/ MediatR
        mediator.Configure(config =>
        {
            config.RegisterServicesFromAssemblies((typeof(ApplicationServicesRegistration).GetTypeInfo().Assembly));
        });
        
        // Utilizing MediatR pipeline registrations
        mediator.AddLoggingToRequestPipeline();
