Consuming REST API with Swagger / OpenAPI in Xamarin and Uno Applications

I still recall the simplicity of standing up a SOAP service and adding a service reference via Visual Studio by simply entering the url to the WSDL – this scenario just worked…. until we moved on.

Improving Developer Experience with Multi-Targeted Visual Studio Projects

In my previous post on using multi-targeted cross platform projects I showed how you can add additional target frameworks to allow the addition of platform specific code to a library. One of the downsides of this approach (versus perhaps using a shared project) is that the library gets built once for every target framework that’s … Continue reading “Improving Developer Experience with Multi-Targeted Visual Studio Projects”

Cross-Platform Libraries with Multi-Targeting for Xamarin, Uno and Windows Development

The story of cross platform development for Microsoft developers has been one marked by iteration after iteration of .NET framework fragmentation. With .NET 5 the promise is that we’ll return to having a single framework that will be used everywhere…. Sorry, what?? when did we ever have a single framework? For as long as I … Continue reading “Cross-Platform Libraries with Multi-Targeting for Xamarin, Uno and Windows Development”

MVVM Navigation with Xamarin.Forms Shell – Part II

Following my previous post on Mvvm Navigation with Xmarin.Forms Shell there were a few things that I felt I hadn’t addressed adequately.
