Hello,

Welcome to Microsoft Q&A!

First please check if the Classresult class is in the namespace of arithimetic, if it is, then the app should be able to build/run correctly even if it has line warning for its DataType. After you build/run the project, the warning will disappear. However, you need to add some elements to the DataTemplate first, otherelse, it will still throw exceptions.

<ListView ......>
    <ListView.ItemTemplate>
        <DataTemplate x:DataType="local:Classresult">
            <StackPanel></StackPanel>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

After it, build/run the project.
