title: Handling Null Values in F#
body: <p>I need to interop with some C# code with F#. Null is a possible value that it is given so I need to check if the value was null. The docs suggest using pattern matching as such:</p>
  
  <pre><code>match value with
  | null -&gt; ...
  | _ -&gt; ...
  </code></pre>
  
  <p>The problem I'm having is the original code is structured in C# as:</p>
  
  <pre><code>if ( value != null ) {
      ...
  }
  </code></pre>
  
  <p>How do I do the equivalent in F#? Is there a no-op for pattern matching? Is there a way to check for null with an if statement?</p>
