I am trying to optimize the loading times for my WPF prism application. The loading is basically a loop of using reflection to create instances of UI elements and then adding them to the main window (the shell) in a tab control.

Since we are limited to using a single thread to create all the objects, what would be the optimal way to speed up loading / create a better user experience?

These are the options I have so far:

  1. Use lazy loading. Only load the tab when the user first clicks on it. But that would have a 4-5 second delay opening the first time as it gets initialized on demand.

  2. Cache all the reflection calls. I actually did that, but it did not speed anything up at all. Most of the time occurs during the rendering of the controls…

  3. ?

Any suggestions would be greatly appreciated for this tricky problem.

    The best answer to speeding up the loading is to simply hide the container while the visual tree is being constructed.

    This prevents the screen from constantly needing to update itself.

    When all the elements have been added to the visual tree, then setting the container visibility to visible renders the tab container once.

    We also implemented some simple lazy-rendering to the tab control items.

    Net result: loading times from 2 minutes down to about 20 seconds.
