I'm using EntityFramework 5 EDMX designer and would like to combine the first & last name of a person into a single field value (name, for instance) on the entity.
I thought in previous versions there was a way to do this, but I don't see anything available to do what I need to do.
Is this still possible?
No it is not possible. You can create model defined function and use it in queries but it will still not be part of your entity. If your entity is read only you can create database view with combined column and map it instead of the table - it shows also main reason why combining columns into single property is not such easy task. Automatic concatenating during reading is easy but automatic decomposing to save correct value into correct column is hard and error prone.
If you need combined property for anything else than querying you can simply create another partial part of your entity class and add your own computed property. If you need the combined property for querying use the model defined function.
