c# - ConfigureAwait for IObservable<T> -

i'm experiencing deadlock when use blocking code task.wait(), waiting async method inside awaits rx linq query.

this example:

public void blockingcode()   {      this.executeasync().wait();  }  public async task executeasync()   {      await this.service.getfooasync().configureawait(false);      //this rx query doesn't support configureawaitawait      await this.service.receiver       .firstordefaultasync(x => x == "foo")       .timeout(timespan.fromseconds(1));  } 

so, question if there equivalent configureawait on awaitable iobservable ensure continuation not resumed on same synchronizationcontext.

you have comprehend "awaiting observable" means. check out this. so, semantically, code

await this.service.receiver     .firstordefaultasync(x => x == "foo")     .timeout(timespan.fromseconds(1)); 

is equivalent to

await this.service.receiver     .firstordefaultasync(x => x == "foo")     .timeout(timespan.fromseconds(1))     .lastasync()     .totask(); 

(note there kind of redundance here, calling firstordefaultasyncand lastasync that's no problem).

so there got task (it can take additional cancellationtoken if available). may use configureawait.
