Hello,

I've just migrated my application from LLBLgen v3.5 to v4.0.

In LLBLGen v3.5 the “typedList.GetFieldsInfo.PrimaryKeyFields” returned the list PrimaryKeyFields used in the Typed List (selected PrimaryKey Fields from the Entities used in the typed List).

Now with the version 4.0 the PrimaryKeyFields-Property always returns an empty collection.

Why?

Because PrimaryKeyFields is a property which is only valid for when the fields object is in an entity. We refactored the entity fields object in such a way that values aren't stored inside the field objects themselves anymore.

We didn't anticipate that outside entities this property would be used (as it has no designed value outside entities). To mimic the property, do:

var allPkFields = typedList.GetFieldsInfo().Where(f=>f.IsPrimaryKey).ToList();
