Is DbSet<>.Local something to use with special care?

Question

For a few days now, I have been struggling with retrieving my entities from a repository (DbContext).

I am trying to save all the entities in an atomic act

For those who come after, I ran into some similar issues and decided to give the .Concat method a try. I have not done extensive performance testing so someone with more knowledge than I should feel free to chime in.

Essentially, in order to properly break up functionality into smaller chunks, I ended up with a situation in which I had a method that didn't know about consecutive or previous calls to that same method in the current UoW. So I did this:

var context = new MyDbContextClass();
var emp = context.Employees.Concat(context.Employees.Local).FirstOrDefault(e => e.Name.Contains("some name"));
