具有CheckboxColumn的DataGrid不注册SelectedItem

Question

I have a DataGrid in WPF. It binds using MVVM to a ViewModel. It works fine with just DataGridTextColumns that display information regarding my List of objects that the DataGrid binds to. Clicking a row selects it, and this works too, firing off a series of events that allow me to work in depth with the given row and derived information.

I then added a DataGridCheckBoxColumn so I can select items and remove them from my List if needed. This, However, breaks everything. Note, that ViewModel remains unchanged entirely and the SelectedItem event for the DataGrid does not seem to fire at all now. Can anyone help so I can still retain my old functionality but also retain my column of checkboxes that help the user quickly do what he/she needs to do?

Relevant XAML:

<DataGrid Name="ArticlesOverviewDataGrid" IsReadOnly="True" 
          ItemsSource="{Binding Project.Articles}"  IsSynchronizedWithCurrentItem="True" 
          Style="{StaticResource DataGridStyle}"  SelectionUnit="FullRow"
          AutoGenerateColumns="False"   SelectionMode="Single" 
          SelectedItem="{Binding SelectedArticle, Mode=TwoWay}">
    <DataGrid.Columns>
        <DataGridCheckBoxColumn Width="65" HeaderStyle="{StaticResource DgchStyle}" Binding="{Binding IsDuplicate, UpdateSourceTrigger=PropertyChanged}" Header="Duplicate" ElementStyle="{StaticResource DataGridCheckBoxColumnElementStyle}"/>
        <DataGridTextColumn Width="*" HeaderStyle="{StaticResource DgchStyle}" Binding="{Binding Name}" Header="Name" ElementStyle="{StaticResource DataGridTextColumnElementStyle}" />
        <DataGridTextColumn Width="*" HeaderStyle="{StaticResource DgchStyle}" Binding="{Binding Author}" Header="Author" ElementStyle="{StaticResource DataGridTextColumnElementStyle}" />
        <DataGridTextColumn Width="100" HeaderStyle="{StaticResource DgchStyle}" Binding="{Binding PublicationDate}" Header="Publication Date" ElementStyle="{StaticResource DataGridTextColumnElementStyle}"/>
    </DataGrid.Columns>
    <DataGrid.InputBindings>
        <MouseBinding Gesture="LeftDoubleClick" Command="{Binding ShowProject}"/>
    </DataGrid.InputBindings>
</DataGrid>

Again, it all works if I remove the checkboxcolumn, meaning it messes with selecting an Item in the DataGrid, but I cannot seem to find any relevant information on WHY it breaks or how to circumvent this issue.

<DataGridCheckBoxColumn Width="65" HeaderStyle="{StaticResource DgchStyle}" Binding="{Binding IsDuplicate, UpdateSourceTrigger=PropertyChanged}" Header="Duplicate" ElementStyle="{StaticResource DataGridCheckBoxColumnElementStyle}"/>

Try to use a template column and set it's DataTemplate with a checkbox instead:

        <DataGridTemplateColumn Width="65" HeaderStyle="{StaticResource DgchStyle}" Header="Duplicate" ElementStyle="{StaticResource DataGridCheckBoxColumnElementStyle}">
            <DataTemplate>
                <CheckBox IsChecked="{Binding IsDuplicate, UpdateSourceTrigger=PropertyChanged}" />
            </DataTemplate>
        </DataGridTemplateColumn>
