-## InputFile cancel event
-
-The `InputFile` component now supports detecting when file selection is canceled through the new `OnCancel` event callback. This event fires when a user opens the file picker but dismisses it without selecting any files.
-
-```razor
-<InputFile OnChange="@HandleFileSelected" OnCancel="@HandleCanceled" />
-
-@if (isCanceled)
-{
-    <p>File selection was canceled.</p>
-}
-
-@code {
-    bool isCanceled;
-
-    void HandleFileSelected(InputFileChangeEventArgs e)
-    {
-        isCanceled = false;
-        // Handle selected files
-    }
-
-    void HandleCanceled()
-    {
-        isCanceled = true;
-    }
-}

-This enables better UX by allowing developers to provide feedback or clear loading states when users cancel file selection.

 ## BL0010 analyzer for JSInterop
 
 A new Blazor analyzer (BL0010) has been added that recommends using `InvokeVoidAsync` instead of `InvokeAsync<object>` when calling JavaScript functions that don't return values. This analyzer helps developers write more efficient JSInterop code.
