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.

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.

Earlier this year I published a pre-release version of an Azure DevOps extension that wrapped the ApkTool for extracting and re-packing Android APK files.

Pipeline Templates: Complete Azure Pipelines Example for a Uno Project for iOS, Android and Windows

My last post was a bit of a long one as it covered a bunch of steps for setting up the bits and pieces required for signing an application for different platforms.

Deploy Xamarin.Forms Apps to App Center from a Azure Multi-Stage Pipeline using Templates and Environments that Require Manual Approval

Pipeline Templates: Building Xamarin.Forms Apps on Azure DevOps using Templates

One of the things I find frustrating is that for every new project we seem to have to recreate the build and release pipeline.
