MediaPicker Enhancements

The MediaPicker has been extended with support for selecting multiple files and compressing images directly from the API using MaximumWidth and MaximumHeight parameters.

var result = await MediaPicker.PickMultipleAsync(new MediaPickerOptions
{
    MaximumWidth = 1024,
    MaximumHeight = 768
});

WebView Request Interception

You can now intercept and respond to web requests made from BlazorWebView and HybridWebView. This allows for scenarios such as modifying headers, redirecting requests, or supplying local responses.

webView.WebResourceRequested += (s, e) =>
{
    if (e.Uri.ToString().Contains("api/secure"))
    {
        e.Handled = true;
        e.SetResponse(200, "OK", "application/json", GetCustomStream());
    }
};

This release includes numerous fixes and improvements to controls and layout behavior:

• CollectionView, CarouselView, and SearchBar now behave more reliably across platforms, with improvements to selection updates, placeholder color updates, and memory management.
• A memory leak in CarouselViewHandler2 on iOS has been resolved.
• Image resizing and layout adjustments are more accurate and efficient.
• The Switch control now uses the native default "on" color when OnColor is not set.
