Please try with the metadata behaviour to extend the existing person class.

For example, in your EDM, you have person class with the following properties and Person.cs looks like the below one.
Person.cs
public partial class Person
{
//extra code removes for readability
Name,
Age
Gender
Title
}
In the same project, add one PersonExtened.cs or some thing like that.
public partial class Person
{
DisplayName
Address
}
Compile the code.
When you're creating object, you should be able to Person class with Name,DisplayName,Address etc properties.
Don't modify directly to the edm file. When you're doing updating the database, you might loose you're changes.
Hope this helps you.
