title: Trouble Unioning to a table in linq
body: <p>My goal is to grab a sum or the Values column of the linq query <code>AboriginalLnVal</code> which has the following select statement:   </p>
  
  <pre><code>select new { Loan = final.Key, Value = final.Sum(Created =&gt; Created.AppLoanAmount) }
  </code></pre>
  
  <p>Below I grab the Sum of the Values from the query, I make it to a single row linq table.<br>
  and Union it to the existing table of summary.</p>
  
  <pre><code>var sum = AboriginalLnVal.Sum(x =&gt; x.Value);  
  var TargetValue = new { Section = "2.1.2 (a)", Activity = "$ Value of Closed Deals by Aboriginal", Result = sum };  
  var TargetValueLinq = Enumerable.Repeat(TargetValue, 1);  
  combineFunction = combineFunction.Union(TargetValueLinq);
  </code></pre>
  
  <p>error produce:   </p>
  
  <pre><code>Error   2   'System.Collections.Generic.IEnumerable&lt;AnonymousType#1&gt;' does not
  contain a definition for 'Union' and the best extension method overload 
  'Telerik.Windows.Data.QueryableExtensions.Union(System.Linq.IQueryable, System.Linq.IQueryable)' 
  has some invalid arguments  
  </code></pre>
  
  <p>If I can possible get some guidance that would be great, I believe I have to convert sum to to make it compatible But Not entirely sure, Quite new to this. 
  System.Linq has been called</p>
