Shows how to reduce your app's startup time by deferring the creation of elements defined in your markup until you really need them.

x:DeferLoadStrategy sample

Shows how to reduce your app's startup time by deferring the creation of elements defined in your markup until you really need them.

Note: This sample is part of a large collection of UWP feature samples. You can download this sample as a standalone ZIP file from docs.microsoft.com, or you can download the entire collection as a single ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

Specifically, this sample shows how to:

  • Create incidental UI when needed: By responding to an event and calling FindName, you can realize your elements based on user interaction.
  • Create adaptive UIs that are less expensive: By deferring elements and then targeting them with the VisualStateManager, you can reduce the footprint of your adaptive UIs in form factors that don't match the specified conditions of the VisualState.
  • Defer control template parts: If you are creating custom controls that has pieces that you expect to not be used as often, you can defer those pieces of the control and only create them if the conditions under which those template parts are used is met.

Note The Windows universal samples require Visual Studio to build and Windows 10 to execute.

To obtain information about Windows 10 development, go to the Windows Dev Center
