Xamarin Android Support Design Library Not Available

Question

I have added the Xamarin Android Support Design Library (and all of its dependencies) using NuGet in Visual Studio, but when I go to use a component in my AXML code it says it is an invalid child element. From all the documentation and examples I could find, it doesn't seem like anything extra needs to be done other than adding the package via NuGet. I can see all of the libraries in the References folder in the Solution Explorer.

I'm sure I'm missing something incredibly simple, but I cannot find what is wrong. Any help would be appreciated. Thanks!

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
   xmlns:p1="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   p1:orientation="vertical"
   p1:layout_width="match_parent"
   p1:layout_height="match_parent">

   <ImageView
        p1:src="@drawable/boxlogo"
        p1:layout_width="match_parent"
        p1:layout_height="wrap_content"
        p1:id="@+id/boxLogo" />
    <android.support.design.widget.TextInputLayout
       p1:layout_width="match_parent"
       p1:layout_height="wrap_content">
       <EditText
           p1:layout_width="match_parent"
           p1:layout_height="wrap_content"
           p1:id="@+id/sku"
           p1:hint="@string/sku" />
    </android.support.design.widget.TextInputLayout>
...
</LinearLayout>

I get the error on the tag with android.support.design.widget.TextInputLayout

I am able to access the libraries in my C# code.

Check the docs for TextInputLayout : https://developer.android.com/reference/android/support/design/widget/TextInputLayout.html

It says:

The TextInputEditText class is provided to be used as a child of this layout. Using TextInputEditText allows TextInputLayout greater control over the visual aspects of any text input. An example usage is as so:

<android.support.design.widget.TextInputLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content">

     <android.support.design.widget.TextInputEditText
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:hint="@string/form_username"/>

</android.support.design.widget.TextInputLayout>

So it seems you need to use an EditText from the support library, eg android.support.design.widget.TextInputEditText
