Answer 1

This is working for me:

project.json add:

"FluentValidation.AspNetCore": "6.4.0-beta3"

startup.cs

services
.AddMvc()
.AddFluentValidation(fv => fv.RegisterValidatorsFromAssemblyContaining<Startup>());

Validation:

public class Foo
{
     public string Bar {get; set;}
}

public class FooValidator : AbstractValidator<Foo> 
{
    public FooValidator()
    { 
        RuleFor(x => x.Bar).NotEmpty().WithMessage("Error Message");
    }
}
