I've followed the Getting Started guide for NUI with XAML for Tizen version 5.0 here: docs.tizen.org/application/dotnet/guides/nui/xaml/get-started-xaml/#create-solution-using-tizen-version-50-and-lower. No matter what, though, I cannot get the code to compile and run. I've set it up as exactly as I can to the guide, but I get errors about missing ContentPage and TextLabel components, and it complains that InitializeComponent is not a valid function. Can someone tell me what I'm doing wrong?
My code is laid out like the attached image

And my project file looks like this:
<Project Sdk="Tizen.NET.Sdk/1.1.7">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>tizen50</TargetFramework>
<AssemblyName>XamlSamples</AssemblyName>

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">

</PropertyGroup>
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">
<DebugType>None</DebugType>
</PropertyGroup>
<ItemGroup>
<Folder Include="lib\" />
</ItemGroup>
<ItemGroup>
<None Update="res\layout\1920x1080\XamlSamplesPage.xaml">
