Hello!
> Fields = new[] { newQueryField("ClassCode", typeof(
string)) { IsKeyField =true }, new QueryField("Priority", typeof(int)) {
IsKeyField = false } }
Here you declare that you have a field ClassCode *in* your composite key,
and Priority *in* your composite value.
But you have neither.
You should use KeyFieldName/ValueFieldName instead (if they present in .Net
API).
