To prevent your WPF (Windows Presentation Foundation) UI from freezing during lengthy operations, you need to ensure that these operations do not run on the UI thread. Here are some strategies to achieve this:
Use Asynchronous Programming
Task-Based Asynchronous Pattern (TAP): Use async and await
keywords to perform operations asynchronously. This keeps the UI responsive while the operation completes.

BackgroundWorker: This is an older approach but still valid for performing background operations. It provides progress reporting and completion handling.

Use Dispatcher to Update UI
When you need to update the UI from a background thread, use the Dispatcher
to marshal the update back to the UI thread.

Summary
Use async
and await
for asynchronous operations.
Use BackgroundWorker
for background processing with progress reporting.
Use Dispatcher
to update the UI from a background thread.
By following these strategies, you can keep your WPF UI responsive and prevent it from freezing during long-running operations.To prevent your WPF (Windows Presentation Foundation) UI from freezing during lengthy operations, you need to ensure that these operations do not run on the UI thread.
