Q: 

How to define an unqiue entity property using ADO.net

Hi,

I've created my entity using ado.net. So far i have the following Fields for the entity person:

PersonId - Primary
ExternalId <-  should be unqiue
FirstName
LastName
[...]

In model.edmx entity view i don't know where to click, so that i can mark the propery "ExternalId" as an unique property.

Thanks in advance for any reply.
