[jira] [Commented] (IGNITE-18820) .NET: Thin 3.0: Add cancellation to all async APIs

["Pavel Tupitsyn (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-18820?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17707788#comment-17707788 ] 

Pavel Tupitsyn commented on IGNITE-18820:
-----------------------------------------

We can't cancel a request with side effects once it has been sent (written to the socket). 

However, cancellation can still be useful:
* We can cancel while waiting on *sendLock*
* We can cancel ongoing retries
