To get around this error you can either:this
Rename your property (recommended):spa
protected bool isNew;
Set your whole assembly to be non CLS compliant:code
[assembly:CLSCompliant(false)]
Add an attribute just to your property:get
[CLSCompliant(false)]protected bool _isNew;
Change the scope of the property, so that it can not be seen outside the assembly.it
private bool _isNew;
