title: What is the difference between declaring a variable using Lambda expression and using = operator
body: <p>I have a very basic question, what's the difference declaring a variable using Lamda and using <code>=</code> operator.</p>
  
  <pre><code>  public static string ID =&gt; "RETAILER_ID";
    public static string ID = "RETAILER_ID";
  </code></pre>
  
  <p>I am sure someone would have asked this in SO, but I could not find it. </p>
