Validation uses examples that are from older versions of FluentValidator

[TheVeryStarlk]

In https://github.com/canton7/Stylet/wiki/ValidatingModelBase#implementing-imodelvalidator-synchronously specfically this part:

public Task<IEnumerable<string>> ValidatePropertyAsync(string propertyName)
{
   var errors = this.validator.Validate(this.subject, propertyName).Errors.Select(x => x.ErrorMessage);
   return Task.FromResult(errors);
}

FluentValidator does not have a method that accepts a string as a property name, but instead, it accepts ValidationStrategy, so it should be something like this:

public Task<IEnumerable<string>> ValidatePropertyAsync(string propertyName)
{
    var errors = this.validator.Validate(this.subject, strategy => strategy.IncludeProperties(propertyName)).Errors.Select(x => x.ErrorMessage);
    return Task.FromResult(errors);
}

Thanks! I've updated the wiki, and the samples will get updated in the next release
