How to set IsUnique within Entity Developer

[Zero-G.]

Hey

I have to place an Index atribute before the property.
How can I do this within Entity Developer?
I Need:

Code: Select all

<Index("IX_FirstAndSecond", 1, IsUnique:=True)> _
Public Property Supplier as Guid

You can add an attribute via interface of Entity Developer in the way described at http://www.devart.com/entitydeveloper/e ... eloper.chm > Basic Workflows > Code Generation > Attributes. Does this help?

Hey
THX. - I still tried this. But I can't find the IndexAttribute from within the DataAnotations.Schema Namespace.

Have you added EntityFramework.dll assembly with its attribute types via the Model Settings window > Attributes?

That solved the Problem.
But for Information:
The Visual Basic Template for Self-Tracking Entity isn't working correct after adding the EntityFramework.dll for the aspects.
The reason is, that The Property EntityState is getting ambigous. And so all properties have to been set explicit to Data.EntityState.

Have a nice day!

Please send us a small test project so that we can reproduce the issue in our environment.
