so my team and I developed an app in Xamarin Forms cross-platform. Now we have also a database in SSMS 2017. For testing purposes I would like to send like a entry form with this fields:
Username: _____ ID#: _____ phone: ______
From my app I have to send this information to my database base that is already created with also those nodes. My actual app has more entry fields, but for now I'm just testing. I have done some research and the best option is to use a web service but I just don't know where to start from. Please help.
