I download Xamarin.FFImageLoading.Forms in Nuget, the discription says it support uwp. I followed FFImageLoading/samples/Simple.WinUniversal.Sample/, and in MainPage.xaml, refered 

xmlns:ff="using:FFImageLoading"
xmlns:fft="using:FFImageLoading.Transformations"

I want to use FFImage, so 

        <ff:FFImage Name="Image"
                Grid.Row="1"
                VerticalAlignment="Stretch"
                HorizontalAlignment="Stretch"
                TransformPlaceholders="False"
                LoadingPlaceholder="loading.png"
                ErrorPlaceholder="error.png"
                CacheDuration="30"
                RetryCount="3"
                RetryDelay="250"
                Height="500"
                Width="500"
                DownsampleToViewSize="True"
                DownsampleMode="None"
                Source="http://loremflickr.com/600/600/nature?filename=simple.jpg">

    </ff:FFImage>

But the designer shows

Unknown type 'FFImage' in XML namespace 'using:FFImageLoading'

So, what's the correct way to use FFImage. Thx.

How to use FFImageLoading's FFImage in uwp project

Please check this line, it is Xamarin.Froms control, it could not be used in native uwp project.

For uwp platform we suggest use ImageEX to replace that one. For more please refer this document .

<controls:ImageEx x:Name="ImageExControl1"
     IsCacheEnabled="True"
     Source="/Assets/Photos/LunchBreak.jpg"
     PlaceholderSource="/Assets/Photos/ImageExPlaceholder.jpg"
     Style="{StaticResource BaseStyle}"/>

  • For some reason, like a home page designed liked NetFlix, `ImageEx` will causes a huge memory usage when navigating back, while set home page `NavigationCacheMode = NavigationCacheMode.Required/Enabled;`. – Vincent Nov 28 '19 at 06:20
