-----------------------------------
> .Net: Improve Task-based async API efficiency with TaskCompletionSource
> -----------------------------------------------------------------------
>
> Key: IGNITE-1791
> URL: https://issues.apache.org/jira/browse/IGNITE-1791
> Project: Ignite
> Issue Type: Improvement
> Components: interop
> Affects Versions: 1.5
> Reporter: Pavel Tupitsyn
> Assignee: Pavel Tupitsyn
> Fix For: 1.6
>
>
> Currently we use TaskFactory.FromAsync to create tasks and return them from
> API. This requires implementing IAsyncResult, which has a heavyweight
> WaitHandle inside. TaskFactory then uses
> ThreadPool.RegisterWaitForSingleObject to wait on that handle and set task
> completion.
> Creating WaitHandle and waiting on it are redundant extra steps.
> [TaskCompletionSource|https://msdn.microsoft.com/en-us/library/dd449174(v=vs.100).aspx]
> allows lighter-weight approach.
