Things Happened

Now everyone knows that you have to use “throw;” to rethrow an exception with the original stack. But when your requirements don't allow to get throw at once? This happens with async tasks quite often. Starting from .net 4.5. you have a helper class that captures all required info and rebuilds exceptions stack:

I got an idea to replace (hide) on fly JSON object responses from the server API on the logger with help of short REGEX:

Its concept in C#5 with TPL are very close to a popular javascript framework - Promises.

The general usage pattern is: var task = DoAsync();

if( task.IsCompleted) { /* process task.Result */ }

task.CompleteWith(t=>ProcessSuccess(t), TaskContinuationOptions.NotOnFaulted);

task.CompleteWith(t=>ProcessError(t), TaskContinuationOptions.OnlyOnFaulted); /*t.Exception.InnerException*/

Also its recommeded to keep all async operations together, mix with synchronous will cost you all of async benefits vapored and can produce thread locks.
