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.

It appears that the Runtime Parameters of Azure DevOps Pipelines has rolled out to most organisations.
