Consider an implementation of the Entity Framework in a DAL assembly. I am needing to add a custom read-only property to an entity.
Person Class, as defined in the DB, contains fields like:
PersonID FirstName LastName In the above example, I’d like to make a property called FullName. It would be the concatenation of
FirstName + ' ' + LastName;
Can anyone help point out in the .edmx file whereabouts to define this new property? Perhaps it’s done within the GUI designer?
In the current version of the EF, the only way to do this is as a .NET function in your partial class for the entity. This means you can’t use the new property in LINQ to entities or ESQL, but it works very well otherwise.
A possible workaround is to do it on the DB server, but the EF would be totally unaware of the relationship between the properties.
In a future version of the EF, this will be supported in the EDMX.
