    .Build(args)
    .RunAsync();

void MapEndpoints(WebApplication app)
{
    app.MapPost<CreateJobResponse>("/job", "CreateJob", "Create a new job.",
            async (JobHandler handler,
                   [FromBody(EmptyBodyBehavior = EmptyBodyBehavior.Disallow)] CreateJobRequest request,
                   IValidator<CreateJobRequest> validator)
                => await handler.CreateJobAsync(request, validator));
}

JobHandler.cs

internal async Task<IResult> CreateJobAsync(CreateJobRequest request, IValidator<CreateJobRequest> validator)
{
    var validationResult = await validator.ValidateAsync(request);
    if (!validationResult.IsValid)
        return Results.ValidationProblem(validationResult.ToDictionary());
    ...
}
