I created my fist WPF app under .Net Core 3.1 in the latest VS 2019. Its just the stock Window when the project is first created and I want to set the Windows icon so I visited the project properties and clicked the link to add Resources. This creates Resources.resx under a Properties folder. I imported an existing favicon.ico into the resources and then tried setting the main Window's Icon="Resources/favicon.ico" resulting in an error for that property.
I've read that a "build action" is needed but I see no button or property for that.
How is the problem resolved? Thanks,
