Hello,

I updated an app using Net 4.7.2 + EFc 3.1 to Net 5 + EFc 5; without asking EFDesigner to regenerate the files, everything run fine.

Today, i also updated EFDesinger to the latest version, and changed the 'Entity Framework Package Version' of my 'efmodel' to the '5.0.Latest'; this produces an error each time i have an 1 to 1 unidirectional association between en entity and a dependant entity. The error messages are like this one:
Organization.Address --> Address: The association from Address to Organization must be 1..0-1

Is this caused by a changes in EFc 5 that i did not saw or by the new version EFDesigner?

Regards
