Hi @mtheolog,
There is nothing wrong with your code. The error is most likely caused by a wrong connection string or a network connectivity error.
Here are some tips:
- Try to copy-paste the connection string from the Azure portal verbatim.
- Try running it on the device that has stable network connectivity -- for example your dev machine (does not have to be an IoT device like Raspberry Pi).
- Try changing the transport type in
CreateFromConnectionString
fromHttp1
toAmqp
orMqtt
. This will not solve the problem but might give a different error message that can give us a clue of what's going on.

@mtheolog - We assume the issue is solved. If that's no the case, please feel free to reopen. Thanks.

Same problem, Almost same code.

@mtheolog please add more information: what Windows SDK version are you using?
Could you please provide network logs following instructions here: https://github.com/dotnet/corefx/blob/master/Documentation/debugging/windows-instructions.md#traces (easiest way is to use the scripts at https://github.com/dotnet/corefx/tree/master/src/Common/tests/Scripts/Tools). Also having a Wireshark trace taken at the same time with the ETW traces would enable us to look at network-level information.
For transient errors you can try the new retry policy: 42b32b5

Thank you for the quick response. I am working on a dragonboard 410c (windows 10 iot core). I enabled the Realtime ETW tracing providing the GUID of the application and caused a deliberate transient error with the scenario I described in my previous post. I did not get any events in the ETW tracing. Logman is not available in windows 10 iot core and I am not sure if I used correctly the ETW tracing.
I will have a look at the new retry policy you suggested.

You could be hitting https://github.com/dotnet/corefx/issues/20470.
Did you run the UWP application without compiling it using ILC? (Using the F5 / Debug option from Visual Studio instead of using Ctrl+F5 or building a Release version?)
Also, Windows IoT seems to have the xperf tool available: https://docs.microsoft.com/en-us/windows/iot-core/manage-your-device/eventtracing

OK thanks. I will try it.

Please reopen if still having issues.
