This always means you’re somehow activating the x86 code from an x64 process, or activating the x64 code from an x86 process. Are you running with “Any CPU”? I think I might have experienced this issue when running in my visual studio debugger but it only happened one time. You don’t have the project online at all for me to look at and try do you? I also notice that this is with the older code base. Do you need to use the older code? The newest library was updated with all the linux+mac binaries and should have this problem sorted.
Can you uncomment the native debugging lines to get the native logs:
//API.NativeLogger = API.DefaultConsoleLoggerFunction;
//API.InitializeZiti(OpenZiti.Logging.ZitiLogLevel.DEBUG);
That will output extra logging from the native debugger to your console for view. There might be some useful information in there. My guess is that the service is somehow setup incorrectly or that a router is offline. Get the DEBUG logs and let me look at that please?
Used the express install to create a local network. Here are controller, edge-router and application logs:

I see a bug in the setup script. See ziti-sdk-csharp/weather.ps1 at main · openziti/ziti-sdk-csharp · GitHub
There’s no space between the closing quote and the double hyphen. That might be the cause:
ziti edge create service 'weather-svc'--configs ..... (no space)
should be
ziti edge create service 'weather-svc' --configs ..... (has the space)
I’ll push a patch for that shortly, I think that’s what happened. I’ll try to replicate that as well. thx
Hi @TheLumberjack, Thanks for your updates.
We have created Endpoint, Service and AppWan for Weather sample in Ziti Console using our NetFoundry account. We followed the same steps as like the below community discussion.
Post creation of above steps, downloaded the jwt file from ziti console and completed the enrollment process using the sample app and got the respective Json file. But when we try to fetch the weather details by passing Json as input, facing ‘Location access violation’ error. PFA.
Where we need to set the location either it picks automatically from device or need to set it somewhere in project?
PFB the sample Weather project we tried to get Weather details.
https://drive.google.com/file/d/1QxNZyK_QrgyIb9EDC9ls2A3pyA9Cb9Gf/view?usp=sharing
This sample project has older .NET version of SDK because that is compatible to our application.
Kindly help us resolving Access location violation issue.
Hi @RS_MOB, the “Access violation”, from my experience, has always been a problem of the launch arch not matching the library. Native libs and dotnet can sometimes be a little tricky. Previous SDKs might have had issues determining exactly which native arch to launch…
Also, thanks for the project. I downloaded it and opened/ran the Ziti.Samples.sln just as it came from that zip file. However, it launched under “Any CPU” (the only configuration in the solution) fine. I added an x64 and an x86 and both of those launched fine too, which confused me. I expected to see the access violation you referenced with one or the other.
Do you have any more details you can share about how you launched the app? Any parameters, run config etc? I can’t trigger the problem you’re seeing yet… 
Also, the older SDK functions/API was replaced with the “Ziti_lib” functionality from the CSDK. I’m concerned for you that using the older code will make a bit of work when you upgrade later on. Please do be aware of that. If there are functions in the older library that you need/want, I’d like to hear that feedback too as it’ll help us determine what functionality people are wanting/using.
I’m also interested in your dotnet version – what are you running? Is it .NET Framework 4.x? or .netcore 3?
Hi @TheLumberjack Thanks for the update.
We are still facing the same Access violation issue during runtime of C# console application.
Since eventually we need this SDK to be implemented in Xamarin based Mobile application which is on C#. So we tried sample mobile app with Ziti.NET.Standard nuget versions from 0.7.112.23262 till 0.8.300.26813 to get Weather details but facing below exception during runtime,

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:
dotnet run weather setup-scripts/weather.demo.jwt

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!
