Correct association mapping in Entity Framework
- by Matt Thrower
Hi,
Trying to change two relationships in our entity framework from many-to-one to many-to-many relationships. So I tried the obvious thing: clicked on each association on the diagram, changed the appropriate end of the association accordingly and then changed the name of the navigation property to a plural to reflect the change.
This lead to the following build error, or one each for the two changes I've made:
Error 3002: Problem in mapping
fragments starting at line
1761:Potential runtime violation of
table CustomerServices's keys
(CustomerServices.Id): Columns
(CustomerServices.Id) are mapped to
EntitySet
CompiledDatabaseCustomerService's
properties
(CompiledDatabaseCustomerService.CustomerService.Id)
on the conceptual side but they do not
form the EntitySet's key properties
(CompiledDatabaseCustomerService.CompiledDatabase.Id,
CompiledDatabaseCustomerService.CustomerService.Id)
I'm not entirely sure why this is happening, so unsurprisngly I haven't had much luck fixing it. I've tried fiddling with the mapping details and adding referential constraints to no avail. Anyone point me in the right direction?
cheers,
Matt
