title: Entity Framework and Case Insensitive String Search
body: <p>I have a Entity Framework entity with a string Property named Description.<br>
  Searching for all entities where the Description contains a string is as simple as:  </p>
  
  <pre><code>var res = from u ctx.Users where u.Description.contains(str) select u;
  </code></pre>
  
  <p>But suppose I want to support case insensitive search?</p>
