Suggestion diagnostic for 'await using' and 'await foreach'

[jnm2]

Version Used: VS16.5.2

ReSharper has this. It's a super nice way to be made aware when methods you're already using can now be awaited in await using or await foreach statements.

// ℹ Use 'await using'
using var stream = File.Create(path);

Result:

await using var stream = File.Create(path);
