Here is the exception details by itself:

After taking a few minutes to load and giving me this exception, the designer view will function but it is so slow that it is virtually unusable, and will make my whole VS session lag (It corrects itself when the designer view is closed).

I'm not experienced in XAML, so I need a way to visualize as I create. Is there a way I can fix this, or a free extension that I can use instead?

Answer 1

Fixed! This was done by uninstalling .NET 4.6, installing .NET 4, reinstalling Windows SDK, and then reinstalling all the necessary .NET packages.
