I have added a property to a subclassed entity, the property is DaysLate and it has some internal calculations and null checks to determine how many days late an item is. However, when attempting to project this onto a DataView, I ran into an issue where there is no MyProjectItemFields (the base class is ProjectItemEntity). Is there a way to project my custom properties onto a DataView, or is there a better way to do this than projection?
Is there any reason why you couldn't put this extra field in a user code region or in a partial class of the entity? This is how I usually handle calculated properties for entities.
