升级到Xamarin Forms 2.0后，为什么会出现此错误？

Question

For context, I am creating an activity indicator in Xamarin Forms that brings up a new transparent page so it blocks user interaction.

Anyway,

Everything is fine with Xamarin Forms 1.3, but when I upgrade to XF 2.0, I'm getting this issue.

Here is my code behind for the Xaml

ModalSpinnerPage

From the auto generated class, It looks like Xamarin thinks my ModalSpinnerPage is a member of Xamarin Forms (although its clearly not)

Again, my problem is that after the Xamarin forms upgrade, Xamarin thinks my ModalSpinnerPage is a member of Xamarin Forms. Everything is fine before the upgrade though. Any help on this would be awesome. Thanks

Answer 1

You need to add correct namespaces:

<sp:ModalSpinnerClass xmlns:sp="clr-namespace:XSpinner.FormsPlugin;assembly=XSpinner.PutHereCorrectAssemblyPath" /* the rest of properties */>

</sp:ModalSpinnerClass>

Here it's working example (using custom pages as a base): link

Answer 2

The following code can work:

<ModelSpinner:ModelSpinnerPage xmlns="http://xamarin.com/schemas/2014/forms"
         xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
         xmlns:ModelSpinner="clr-namespace:XSpinner.FormsPlugin"
         x:Class="XSpinner.FormsPlugin.ModelPageSpinner">
</ModelSpinner>
