Reference with two fields

[askrinnik]

Hello,
I have two tables with a reference by two fields. I put the following attribute to my reference property:

[Reference(ReferenceType.OneToOne, ColumnName = "col1,col2", ReferenceMemberName = "col1,col2")]
public Invoice Invoice { get; set; } = new();

But it doesn't work
I found out that the ComplexSqlBuilder.GetJoinExpressions() supports only one field in a ColumnName and ReferenceMemberName
Is it possible to add reference support with more than one field?

Or is there another solution for my scenario?

Thank you in advance
