title: Possible to add a condition for linked table fields in LINQ
body: <p>Can someone suggest me a solution to add condition for reference table items in linq.</p>
  
  <p>I have a master table called TourPackage, which include</p>
  
  <pre><code>public class TourPackage{
     public int TourID { get; set; }
     public string TourName { get; set; }
     public List&lt;IncludedItems&gt; IncludedItems { get; set; }
  }
  </code></pre>
  
  <p>Every tour package contain some selected items reference like</p>
  
  <pre><code>public class IncludedItems {
     public int TourID { get; set; }
     public int IncludedID { get; set; }
     public Included Included { get; set; }
  }
  </code></pre>
  
  <p>All included item should have a reference to Included  table for lookup reference</p>
  
  <pre><code>public class Included {
     public int IncludedID { get; set; }
     public string IncludedValue { get; set; }
  }
  </code></pre>
  
  <p>now i have set of IncludedID like [1,2,3], Is it possible to filter TourPackage based on IncludedID.</p>
  
  <p>Thanks in advance</p>
