The local variable isn't helpful as it doesn't contain any common expression.

Definition of DisconnectResults
private Dictionary<ulong, DisconnectAsyncResult> DisconnectResults =>
LazyInitializer.EnsureInitialized(ref _disconnectResults, () => new Dictionary<ulong, DisconnectAsyncResult>());So every access of DisconnectResults is a call to LazyInitializer.EnsureInitialized.
So using the local variable only one call is necessary.

What do you want to do?
Remove the local variable and directly access DisconnectResults (this will result in more Volatile.Read of _disconnectResults) or do you have another comment.

HttpListener isn't so optimized. I don't think reducing several volatile reads can result in real world difference. Let's focus on fixing only.
