I have a SP I call that takes 1 or 2 minutes to run.

I am running into the error:

system threading taskcanceledexception a task was canceled

atm the SP takes 1:08 to run.

At 35 seconds, using filters to get less data back, it runs fine!

We have many reports that take a bit to run.

How to I get this task thing to stop killing my app.

The task is cancelled from where?  The browser?

Browser.

It says something has happened, reload.

Doing the Inspection thing I see a System.Threading.Tasks.TaskCanceledException

as the first error.

Appears to be timing out somewhere.

I know the data from the SQL server is back from stepping thru the code.

I would check the timeout on the httpclient, the browser, etc.  Have you verified using Fiddler?

It appears I was calling the routine incorrectly!

What I had:

await getData_ProdResultRtp3(strWhoIAm);

What now seems to work:

await Task.Run(() => DoLongSyncOperation());

Not sure what the difference is between those two?

I assume, I know! :(, the 2nd one force it to wait till that routine is done?

sorry:

 await Task.Run(() => getData_ProdResultRtp3(strWhoIAm));

for the 2nd cmd.

 

No answers yet. Maybe you can help?
