title: C# fluent assertions result of check as bool
body: <p>I am trying to use Fluent Assertions on C# outside of test frameworks. Is there any way I could cast an FA check to bool? For example I need to achieve something like:</p>
  <pre><code>bool result= a.Should().Be(0);
  </code></pre>
  <p>If passes then result = true;
  if fails, result = false.</p>
  <p>Is there any way of casting or extracting a <code>bool</code> result from the assertion?</p>
