Designer: Better navigation property names when multiple relationships to the same table


When multiple relationships to the same table are present the navigation properties are just postfixed with a name. We could consider using the FK name or some other means to make it clearer which is which.

This work item originated from connect.microsoft.com. A member of the EF team at Microsoft should close the related Connect issue when closing this work item.

you can use nhibernate for .net for more clear naming.

but i want EF to become more powerful too.

EF Team Triage: We are only taking minimal changes to the designer in EF6 because we are still converting the code base to open source. We'll consider this bug for the next release.

I always use a central Look-up table for my database, and this bug kills me, kindly please fix it a soon as you can, it will make the developer life much easier then when coding with navigation properties.

Trying to go around it by changing name in designer (a nightmare when you update it)
or add some extension properties that reference the navigation properties with incorrect naming. (extra code that is not needed and when updated the edmx sometimes it make problems too.)
or change in the T4 template to generate the navigation properties, but didn't master this yet.

Still a problem in EF 6.0.1

For example, I get 2 properties like:
[EdmRelationshipNavigationPropertyAttribute("Warehouse", "FK_DataOverride_DocumentType_After", "DataOverride")]
public EntityCollection<DataOverride> DataOverrides

[EdmRelationshipNavigationPropertyAttribute("Warehouse", "FK_DataOverride_DocumentType_Before", "DataOverride")]
public EntityCollection<DataOverride> DataOverrides1
where it could simply be:
[EdmRelationshipNavigationPropertyAttribute("Warehouse", "FK_DataOverride_DocumentType_After", "DataOverride")]
public EntityCollection<DataOverride> DataOverridesDocumentTypeAfter

[EdmRelationshipNavigationPropertyAttribute("Warehouse", "FK_DataOverride_DocumentType_Before", "DataOverride")]
public EntityCollection<DataOverride> DataOverridesDocumentTypeBefore
All the information is already in the foreign key name used by the designer.

This is an amazingly painful bug for those of us that have to use existing databases that periodically change. Please provide us a way to customize the navigation naming property on the database side.

Annoying... How long do we have to wait to get this?
