The PythonEngine is part of IronPython. You can download that at http://www.codeplex.com/IronPython/.

I’m not sure if this is what you were looking for, but I added a sample to the validation project that adds a DateTime property to the User class. The updated code is at http://code.google.com/p/codevoyeur-samples/.

The new property, Birthday, is a DateTime with a new Validation attribute.


[Validation("is_valid_birthdate")]
public DateTime Birthday { get; set; }

The validation rule simply checks whether the property value for Birthday is a date prior to now.

<rule name="is_valid_birthdate" message="Birthday must be a date prior to today">
result = property_value.CompareTo(DateTime.Now) == -1
</rule>
