DataGrid using wrong datacontext ?

[nerdkl]

i have this.

public class ExtensionViewModel : ViewModelBase
{
    public ObservableCollection<DataGridItem> Items { get; } = new ObservableCollection<DataGridItem>();
    public ExtensionViewModel()
    {
        Items.Add(new DataGridItem("item 1"));
        Items.Add(new DataGridItem("item 2"));
        Items.Add(new DataGridItem("item 3"));
        Items.Add(new DataGridItem("item 4"));
        Items.Add(new DataGridItem("item 5"));
    }
}

<DataGrid ItemsSource="{Binding Items}" AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Name" Binding="{Binding Name}"/>
        <DataGridCheckBoxColumn Header="Include" Binding="{Binding Include}"/>
    </DataGrid.Columns>
</DataGrid>

the result is

[GeneratedCodeAttribute("Empty Keys UI Generator", "3.2.0.0")]
public class ExtensionViewModel_Name_PropertyInfo : IPropertyInfo {

#error IssueExamples.Base.ViewModel.ExtensionViewModel type does not have property Name
}

[GeneratedCodeAttribute("Empty Keys UI Generator", "3.2.0.0")]
public class ExtensionViewModel_Include_PropertyInfo : IPropertyInfo {

#error IssueExamples.Base.ViewModel.ExtensionViewModel type does not have property Include
}

i saw your example... where is the difference?

You have to set datacontext somewhere. I don't see it in your example.
