title: Why is it not allowed to declare empty expression body for methods?
body: <p>I had a method which has an empty body like this:</p>
  <pre><code>public void Foo()
  {
  }
  </code></pre>
  <p>As suggested by ReSharper, I wanted to convert it to expression body to save some space and it became:</p>
  <pre><code>public void Foo() =&gt; ;
  </code></pre>
  <p>which doesn't compile. Is there a specific reason why this is not supported?</p>
  <p>And I think I should open a bug ticket for ReSharper since it refactors code to a non-compilable version.</p>
