Description

Version Used: Version 16.9.0 Preview 3.0

Steps to Reproduce:

  1. Set a variable to an asynchronous await call var root = await document.GetSyntaxRootAsync(cancellationToken).ConfigureAwait(false))

  2. Do not use the variable

  3. Create an asynchronous method

  4. Do not call the asynchronous method

Expected Behavior: Green underline appears underneath root and method header name indicating that the variable/method is unused.

Actual Behavior: The unused warning does not appear.

Note: I may be missing an option selection that would make it so the warning appears in this case, but I am unsure.
