Work on Your UI, in the State You Need
Work on pages and components in the exact UI states and data conditions
you need, without navigating through your app to reproduce them.
Edit The Real UI
Edit the actual page or component from a Preview. Changes are saved to the source used by your application and reflected wherever that UI is used.
Validate Beyond the Happy Path
Check loading, empty, error, edge-case, and data-specific states while you work.
Go Straight to the State You Need
Open the UI and state you need directly, without repeating navigation or recreating the runtime conditions required to reach it.
The States You Need Aren't Always Easy To Reach
Loading, empty, error, and edge-case states can mean changing data, throttling a connection, forcing a failure, or navigating through the same workflow again.
Bring the UI Into the State You Need
Instead of recreating conditions in the running app each time, create a Preview with the context and state you need and return to it directly. Start from an implicit Preview, then create dedicated Previews for the states and data conditions you want to return to.
Give Each Preview Its Own Context
Create multiple Previews of the same page or component with different data contexts. Use your application’s data context to represent populated, empty, error, and other data-specific states without depending on a live backend.
Edit the Component, Not a Copy
A Preview provides the context around your UI. It doesn’t create a separate version for you to maintain.
Click Edit to work on the actual page or component. Changes are saved to the source XAML and reflected wherever that UI is used.
Skip the Path. Open the UI.
Working on a page several screens deep shouldn’t mean navigating back to it after every change.
If the answer you need is not here, the documentation covers the surface in full.
Hot Design works on the running application, in whatever state it happens to be in. Previews shows the states a page can enter, at design time, without running it.
Try Previews in Your Existing App
Work on real pages and components across the states and data conditions your application needs to handle.
