So I am using WPF windows as dialogs for a plugin I am working on. However, when the user opens a WPF window for the first time, it is extremely slow. The initial load takes 25 seconds or more. Then every time it opens after that, it opens instantly. What could be causing this? How can I fix it? The window I am trying right now is just an empty WPF window with 1 label. It seems like this should load instantly.
