title: How can I send a message to property validator İsvalid in fluentvalidation?
body: <p>hello fluent validation has been updated to version 10.3.6 but the SetMessage function that was in the properyvalidator that was working before does not work anymore, what should I use instead?</p>
  <pre><code>    public class TcknOrVknPropValidator : PropertyValidator
      {
          public TcknOrVknPropValidator() : base()
          {
  
          }
  
          protected override bool IsValid(PropertyValidatorContext context)
          {
              var propertyValue = context.PropertyValue as string;
              if (string.IsNullOrWhiteSpace(propertyValue))
              {
                  SetErrorMessage(&quot;Tc veya Vergi No Geçersiz&quot;);//this function not found now
                 
                  return false;
              }
  
              if (propertyValue.Length &lt; 10 || propertyValue.Length &gt; 11)
              {
  
                  SetErrorMessage(&quot;Tc Veya Vergi No Eksik Yada Hatalı&quot;);
                  return false;
              }
  
             return true;
  }
