I have been trying to work with CustomVision for 2 days without getting any success. I have tried several different libraries, including Microsoft's own (Microsoft.Azure.CognitiveServices.Vision.CustomVision.Prediction) and opened an issue on its github page.
The only times I have been been able to get a successful response (200 and not 404 status) was when I was using these libraries with Windows. But whenever I tried using the exact same library on an Android application based on Xamarin.Forms, I systematically got a 404 not found response from the API.
Last thing I tried was trying to run the sample in this official Xamarin tutorial but an exception gets thrown before even hitting the API call, and it's also important to note that the nuget library used here has been deprecated (Microsoft.Cognitive.CustomVision.Prediction) so at this point I'm really starting to feel like I will never be able to use this API with Xamarin anyway.
But I'm also wondering, are there actually even people out there who are successfully using this API with Xamarin.Forms?
Any insight or shared-experience on the subject would be appreciated, and thank you for taking the time to read me.
