Question

The default constructor in a generated Entity Framework Entities file is like this:

public ProjectEntities() : base("name=ProjectEntities", "ProjectEntities")
{
    this.OnContextCreated();
}

I want to change it to:

public ProjectEntities() : base(UtilClass.GetEnvDependantConnectionStringName(), "ProjectEntities")
{
    this.OnContextCreated();
}

This is because I want to have a different connection string for all the dev environments and the production environment, and have no chance they are mixed up (which is what my custom method checks).

How do I do that? This code is thrown away every time the designer file is regenerated.

We fixed it by calling our entities ProjectEntitiesPrivate, and what was partial class ProjectEntities before, is now a non partial class ProjectEntities : ProjectEntitiesPrivate, with the constructor I need:

public class ProjectEntities: ProjectEntitiesPrivate
{
    public ProjectEntities():base(UtilClass.GetEnvDependantConnectionStringName())
    {

    }
