    Xamarin.Forms.Xaml.XamlParseException: Position 12:8. Type telerikGauges:GaugeLinearAxis not found in xmlns clr-namespace:Telerik.XamarinForms.DataVisualization.Gauges;assembly=Telerik.XamarinForms.DataVisualization

     

    We are able to reproduce this on 2 machines now with 2 completely different Xamarin projects. The project runs normally and displays the gauge on Android, that error is only thrown with iOS.

    This is even reproducible if you use the Telerik Xamarin Forms project wizard, you will only be able to run on Android

    Hi,

    I was able to reproduce the described runtime exception.

    One way to resolve this is to give an x:Name to the gauge:
    <telerikGauges:RadRadialGauge x:Name="gauge1">

    Another way to go here is to access anything in the DataVisualization assembly so that it gets loaded. I suspect that the reason for this exception is the .Net mechanism of lazy loading of dlls and the xaml parser cannot find the proper type unless an x:Name is given, or a prior initialization was done.

    Let us know how it goes.

    Hello,

    I have just learned that there is one more option - you can turn on XAML Compilation. You can either set the XamlCompilation attribute for the whole portable assembly:
    [assembly: Xamarin.Forms.Xaml.XamlCompilation(Xamarin.Forms.Xaml.XamlCompilationOptions.Compile)]

    Or you can only mark only the page with the gauge:
    [Xamarin.Forms.Xaml.XamlCompilation(Xamarin.Forms.Xaml.XamlCompilationOptions.Compile)]

    We are probably going to include this by default in our Wizard, so that this issue does not occur.

    That makes sense since I noticed the gauge will load on the 2nd or 3rd pages loaded but not the initial page.

     

    Thanks for the fix
