[jira] [Created] (IGNITE-1791) .Net: Improve Task-based async API
efficiency with promise-style tasks

---------------------------------------
Summary: .Net: Improve Task-based async API efficiency with promise-style tasks
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: 1.5
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.
System.Threading.Task has internal API to create "promise-style" task and then set it to completed state when needed.
