How can I enable CascadeMode.Stop from FluentValidation throug IoC on ASP.NET Core 3?

Question

I've seen it somewhere but couldn't find it anymore. Something like the following:

public class Startup {

public void ConfigureServices(IServiceCollection services)
{

services.AddControllers()
                .AddFluentValidation(s =>
                {   
                    s.ValidatorOptions.CascadeMode.Stop;                    
                    ...

Answer 1

Response from JeremySkinner the library maintainer:

Either:

using FluentValidation;

services.AddMvc().AddFluentValidation(fv => {
  fv.ValidatorOptions.CascadeMode = CascadeMode.Stop;
});

Or just:

ValidatorOptions.Global.CascadeMode = CascadeMode.Stop;

Both have the same result (they're the same configuration instance)

Answer 2

I believe it should be:

ValidatorOptions.CascadeMode = CascadeMode.Stop;
