In this post, I will describe how to port a desktop application from .NET Framework to .NET Core. I picked a WinForms application as an example. Steps for WPF application are similar and I’ll describe what needs to be done different for WPF as we go. I will also show how you can keep using the WinForms designer in Visual Studio even though it is under development and is not yet available for .NET Core projects.
