Building A Cross Platform App with Xamarin

So, I made an app.  A for real, runs on things app.  More accurately, I followed a little tutorial to make an app, as part of the Xamarin Challenge over at  The app itself is a little weather app, it even includes location based weather and forecasting.  I know this isn’t particularly impressive but I think it’s pretty neat.

Part of the point of the exercise is that it show off the cross platform ability of Xamarin as a development plaform.  The end app uses the same code and runs on Windows 10, iOS and Android.  Unfortunately, I don’t own a MAC or an iOS device to test the iOS code but I was able to run both the Android and Windows 10 versions of the App.  I even ran the Android APK on my Fire Tablet.

I can’t say I learned a ton about how to actually make apps using Xamarin, though I plan to poke through the code provided more later.  What I learned more of was how to trouble shoot Visual Studio, which seems to be a bit more than buggy.  There is a forum set up for people looking for assistance on this contest and there are a lot of issues that all seem unrelated to each other but all related to issues with Visual Studio.

For example, I had issues getting the location based weather to work, until I went through and updated the Android Emulator files and build an emulator that ran on Android 7.  In a later step I found several of the NuGet packages weren’t installing properly, I never really figured out why but I ended up having to add them individually to each of the app platforms rather than the blanket “Install this on all platforms” system.

In the end, I did manage to get through and the app says everything was submitted and accepted.
