.Net

I’ve been tinkering with Visual Studio 2010 Beta1 and the .Net 4 framework. One of the things that I’ve tried is filling a DataGrid with the results of a LINQ query. Consider the following code: C#

var voyages = from voyage in entities.Voyage
              select new { Number = voyage.Number, ETA = voyage.StartTime };

dataGridTest.ItemsSource = voyages;

XAML

<DataGrid Name="dataGridTest">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Number" Binding="{Binding Path=Number}" />
        <DataGridTextColumn Header="ETA" Binding="{Binding Path=ETA}" />
    </DataGrid.Columns>
</DataGrid>

Seems straightforward enough, doesn’t it? Well it does but when you try to run it, it’ll crash and burn with the following exception:

InvalidOperationException: A TwoWay or OneWayToSource binding cannot Meer >
