If I understand this correctly, once I have all possible validation classes implemented with the same interface... should I just leave the *.cs files by themselves or do I need to compile those as well so the main class can load them?

If you happen to have a small working project similar to what we are trying to accomplish here, can you share it?

public interface IValidator
{
   bool Validate(object itemToValidate);
}

public sealed class FirstValidation : IValidator
{
    public bool Validate(object itemToValidate)
    {
        /* Your code for validation */
    }
}

public sealed class SecondValidation : IValidator
{
    public bool Validate(object itemToValidate)
    {
        /* Your code for validation */
    }
}

<applicationSettings>
    <TestApplication.Settings1>
        <setting name="ValidationClasses" serializeAs="Xml">
            <value>
                <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
                    <string>Test.First</string>
                    <string>Test.Second</string>
                </ArrayOfString>
            </value>
        </setting>
    </TestApplication.Settings1>
</applicationSettings>

foreach (string s in Settings1.Default.ValidationClasses)
{
    Type type = Type.GetType(s);
    IValidator validator = (IValidator)Activator.CreateInstance(type);
    validator.Validate();
}
