I am attempting to use a a custom markup extension with Xamarin forms in order to eventually having localization implemented. I am trying to go a long the lines of the Xamarin form examples.
Here is a pieces of XAML Code that uses the extension:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:CRI.MAP.Mobile.Views;assembly=CRI.MAP.Mobile"
x:Class="CRI.MAP.Mobile.Views.CustomerSearchPage">
<StackLayout>
<Button
Text="{local:Translate Clear}"
Command="{Binding ClearCommand}" />
</StackLayout>
Here is the code for the Translation Extension Markup:
using System;
using Xamarin.Forms.Xaml;
using Xamarin.Forms;
using System.Diagnostics;
namespace CRI.MAP.Mobile.Views
{
// You exclude the 'Extension' suffix when using in Xaml markup
[ContentProperty ("Text")]
public class TranslateExtension : IMarkupExtension
{
public string Text { get; set; }
public object ProvideValue (IServiceProvider serviceProvider)
{
//if (Text == null)
// return null;
//Debug.WriteLine ("Provide: " + Text);
// Do your translation lookup here, using whatever method you require
//var translated = L10n.Localize (Text);
//return translated;
return "hello";
}
}
}
I commented out some of the code just in case that was the cause of the issue.
Whenever I attempt to run this I get the error: Xamarin.Forms.Xaml.XamlParseException: MarkupExtension not found for local:Translate. I am very confused as why it doesn't find the the markup extension as all the examples I look at seem to be done the same way. Does anybody know why this would be? I am having a lot of troubles in general finding good examples for Xamarin forms.
The assembly name is wrong. I was using a shared project for Xamarin forms and had the name of the shared project as the name of the assembly. So if you have a shared project the name of the assembly needs to be the assembly that is using the shared project.
