title: How to negate bool value inside blazor?
body: <p>I'm trying to do this</p>
  
  <pre><code>&lt;MatCheckbox @bind-Value="@(!Checked)" Label="Checkbox"&gt;&lt;/MatCheckbox&gt;
  </code></pre>
  
  <p>But it gives me the error</p>
  
  <blockquote>
    <p>CS0131    The left-hand side of an assignment must be a variable, property or indexer</p>
  </blockquote>
  
  <p>How can I pass a negated boolean value without creating another property?</p>
  
  <p>I want to bind the value so it's <code>!Checked</code></p>
