"Unable to instantiate WindowsPage"

Question

I created the Xamarin.Forms middleware application template. Now I get the error "Cannot create an instance of WindowsPage" in a UWP project. Note. I have not made any changes to the template. Error screenshot

Answer 1

In my case, the error does not interfere with compiling the project and appears only if the MainPage.xaml file is open in the editor. Therefore, I suggest you close this file before creating your solution, and the error will disappear.

Anyway, I hope this helps.
