My team has built a Xamarin.Forms application using VS2017. We are using a Shared project because one of our core functionalities requires ESRI mapping, and ArcGIS Runtime for Xamarin does not support anything but Shared projects at this time.
The next app that my boss wants should be fairly quick to develop if I can use the existing code we've already written for the first app. However, I don't see any way that I can reference that code from another project. I have tried adding a new UWP project to the existing one, but then I have to add all the same NuGet packages, 90% of which are unnecessary to this new project. On top of that, it won't actually compile correctly since the App.xaml is different.
I've searched all over trying to find a solution to this, and haven't come up with anything. PCL is not an option, nor is .NET Standard. Is there any way to accomplish this?
