Concat/Union Tables in LINQ

Question

This current project is more of a proof of concept for a larger project. I have two \"tables\" (represented as lists below), CatList and DogList, t

Answer 1

The generic lists are from different types (Dog and Cat), you have to "cast" them to the target interface before concatenation:

var list1 = DogList.Cast();
var list2 = CatList.Cast();

var bothLists = list1.Concat(list2); //optional .ToList()
