visual studio - Unmangling (pre .NET 4.5) async/await stack traces -

since pre .net 4.5 runtimes (including sl/wp) not async-aware, stack traces generate show compiler-generated class/method names (like d_15).

does know of utility generate better stack trace given runtime stacktrace, assembly , pdb?

to clear: i'm not looking complete async stack, better view of method threw exception

it seems above statement not clear enough, here example:

public async void foo() {     await bar(); }  public async task bar() {     async somethingtomakethismethodasync();      throw new exception() } 

when exception thrown bar, stacktrace contain generated method names (d_15()). i don't care foo called bar. want know bar method threw exception

andrew stasyuk has great article in msdn magazine http://msdn.microsoft.com/en-us/magazine/jj891052.aspx details async causality chains way aid in debugging in light of disjoint , confusing stack traces.
