Get's the calls in a method and adds them to a list. Uses dnlib.

References.cs

private static List<string[]> GetReferences(ModuleDef module)
{
    var typeSet = new HashSet<string>();
    foreach (var type in module.Types)
    {
        typeSet.Add(type.Name);
    }
    var refs = (from type in module.Types from method in type.Methods where method.HasBody from instruction in method.Body.Instructions where instruction.OpCode == OpCodes.Call from set in typeSet where type.Name != set where instruction.Operand.ToString().Contains(set) select new string[] {type.Name, set}).ToList();
    return refs.GroupBy(strArr => string.Join("|", strArr))
        .Select(g => g.First())
        .ToList();
