Linq context behaviour

I am using linq 

var remove = WE.Item.Where(key => !response.Any(p2 => p2.ItemID == key.ItemID)).ToList();

and occure error. This is because i am using ToList()? How to fix it?

Additional information: Unable to create a constant value of type 'IBD.Models.Stool'. Only primitive types or enumeration types are supported in this context.

It looks like you need to pull the ids out of response first so you can pass the list into your Linq provider

var ids = response.Select(p => p.ItemID).ToList();
var remove = WE.Item.Where(key => !ids.Contains(key.ItemID)).ToList();
