In MS Visual Studio Express 2013 for Windows Desktop:
I\'m learning C# and following an example that shows how to create a user interface in a .xaml file. https://ms
Well this is an old post but I just found another way the designer can hide even when it is configured correctly in VS2019. So here is what happened to me:
XML designer was enabled and all should have worked except the designer was not showing....except it was, just hidden away in a split view slider that had zero width! I can only presume this was because I change monitors a lot on my PC and have resizing of windows going on quite often between monitors of different resolutions.
At any rate search around in the dark on dark nothing around the xml view, grab the split view slider and slide and the designer will show up in no-zero size in the real world....
