To get around this error you can either:

1. Rename your property (recommended):

   protected bool isNew;

2. Set your whole assembly to be non CLS compliant:

   [assembly:CLSCompliant(false)]

3. Add an attribute just to your property:

   [CLSCompliant(false)]protected bool _isNew;

4. Change the scope of the property, so that it can not be seen outside the assembly.

   private bool _isNew;
