Problem creating a 1:1..0 (One:One or Zero) Association
Posted: Mon 07 May 2018 16:54
Hi DevArt Team,
I have a problem creating a 1:1..0 (One:One or Zero) association. I have
I want to enter now the following association:
But I get the following error during the valid check:
Multiplicity is not valid in Role 'TableB' in relationship 'TableA_TableB'. Because the Dependent Role properties are not the key properties, the upper bound of the multiplicity of the Dependent Role must be *.
Only a Id - Id 1:* association works without a problem, but thats not what I want.
I use the newest ED version 6.2.487, EF 6 model, Code First.
Whats wrong?
Thank you
Florian
