So I wrote this, not sure if it's right, because I get 0 back, and there's 4

Do you think this is because the database was already existing, and it's related to Code First.

On the previous function, I'm not sure if I'm getting data back or not, and not quite sure how to use the returned output.

Uhhhh, what does this have to do with a Count or a list of movies?

I used ConfigurationManager.ConnectionStrings("DefaultConnection").ConnectionString
as the conn string in my new in context. But I changed to your version, You must have a good reason for it; I'll learn down the as to why.

Is it good practice to create a new context and just pass it along? with using. I think that would get disposed as well.
