Hi @Paul Ryan ,
According to the official code sample, you need to add a namespace reference x:Class="YourProjectNameSpace.YourDictionaryXamlFileName"
to this ResourceDictionary, and the content of ResourceDictionary cannot be empty.
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:muca="using:MUA_Common.Model.Appointments"
x:Class="YourProjectNameSpace.YourDictionaryXamlFileName">
<DataTemplate x:Key="AppointmentLineTemplate" x:DataType ="muca:AppointmentModel" >
<Grid>
</Grid>
</DataTemplate>
</ResourceDictionary>
Thank you.
