Hi @RS_MOB,
I’ve not tried the .NET sdk with xamarin myself, so I don’t know what sort of issues might happen when I try that.
I’ll spend some time and try to make a sample Xamarin app and see how it goes for me…
@RS_MOB, I was updating my environment and looking things over when I found a StackOverflow post indicating that Xamarin was deprecated and leaving support in 2024. Microsoft link to the announcement here.
From that page:
.NET 6 takes over from Xamarin for building Android, iOS, and cross-platform applications. Xamarin.Android and Xamarin.iOS projects should be upgraded to .NET SDK-style projects. Xamarin.Forms projects should be upgraded to .NET Multi-platform App UI (MAUI).
Would an example that uses MAUI be acceptable? I'd like to keep us up-to-date with "current/future" best practices and it sounds like that's MAUI, not xamarin. Let me know please, thanks
@TheLumberjack Thanks for your update.
MAUI is in our roadmap, should take another 6 to 8 months for adoption. Xamarin is our current platform for our mobile application and will continue to use it till Microsoft supports it.
We will wait for your sample Xamarin app
Hi:
Recently, when I try OpenZiti on Ubuntu 22.04, there are two problems I cannot solve.
First:
We want to use the Python SDK in our local simple server-client Python application, we create the two Python codes and after we do this :
pip install Openziti
We still need the id.json file.
However, I cannot generate the id.json file correctly after several trys. Could you please provide some guidances on Python SDK?
The second problem:
After I found I cannot solve above problem, I was trying to find the similar problem in this forum. Then, I found this C# sample. Everything runs well in the beginning. However, when I try the C# sample:
I got the following error:

Thank you vert much
Looking forward hearing from you
Can you elaborate on how you tried to make the id and which python sample you're running?
For the C# demo, it seems like our dependency is out of date in nuget somehow. I'll see if I can fix that, thanks for letting us know.
Hi @Nick, I pushed a chang out to main to fix that sample. Do note that the proper way of running it from the Samples folder is by running just dotnet run weather. Thanks for pointing that out
Take a look a this gif I just made and you can watch me run it
Hi:
Thank you for your solution.
However, when I do that, it show following output:

If this is the first time running this script, allow
time for the services to propegate to the router
before running the sample or you may receive an error
like: no terminators exist for service
then, execute the sample using:

After above, there is no further output, which should be the weather info.
Do you have an idea about this ?
BTW, all the above codes are running on local Debian machine in a same terminal.
Hmmm. “no output” is definitely unexpected. It looks like the “native” logging isn’t working on this sample.
OpenZiti.Logging.SimpleConsoleLogging(LogLevel.Trace);
OpenZiti.API.NativeLogger = OpenZiti.API.DefaultNativeLogFunction;
Those lines are usually commented out. I’ll dig in a bit more. My guess is that your client isn’t able to connect to an edge router or to your controller and it’s just sitting there never timing out.
I ran from Ubuntu on WSL, I don’t think that would matter and it’s debian-flavored. I’m more troubled the lack of output though. Do you see any logs from your router at all?
After I changed OS to Ubuntu 22.04.2, it becomes better.
However, there is still an error in the last step:
I am not sure if it is the problem in C# code, or it is problem in my configuration:

Sorry, we are running out of queries to the weather service at the moment.
Here is the weather report for the default city (just to show you what it looks like).
We will get new queries as soon as possible.
You can follow https://twitter.com/igor_chubin for the updates.

I think, it means the application build is correct, just the weather service from “wttr.in” not available, right ?
OR, it is my building problem ?
Yeah that’s what happens when they service too many requests. If you’re getting that response, it worked! As for debian, I wonder if you had a firewall enabled that ubuntu didn’t have enabled?
Looks like it worked!
