How to data bind simple ViewModel to WPF Datagrid?

that's perhaps an absolute newbye question.

I try to bind a simple Viewmodel Person.allinstances with Firstname: string, Lastname: string to WPF DataGrid.

ViewModel:

enter image description here

XAML:

<Window.Resources>
    <ecoVM:ViewModelContent x:Key="VM1" ViewModelName="AllPersons" EcoSpaceType="{x:Type ecospace:RelativesEcoSpace}" ></ecoVM:ViewModelContent>
</Window.Resources>

           <Grid DataContext="{StaticResource VM1}">
                <DataGrid AutoGenerateColumns="True" ItemsSource="{Binding ?????}" />
           </Grid>

Code Behind:

(Resources["VM1"] as ViewModelContent).SetEcoSpace(_es); (Resources["VM1"] as ViewModelContent).RootObject = ???;

How should I do it properly?

When you create the ViewModel - check the CodeGen-checkbox. enter image description here

Then CodeGen - and you have a strongly typed VM at your disposal

Use like this:

xmlns:MyVm="clr-namespace:MDrivenMinimalWecpof3.ViewModelCodeGen_FirstView"
...
<MyVm:FirstView x:Key="MyVm"  ></MyVm:FirstView>
...
<Grid Grid.Row="2" DataContext="{StaticResource MyVm}">
  <DataGrid  ItemsSource="{Binding Path=AllSomeClass }" AutoGenerateColumns="True"></DataGrid>
</Grid>

In code behind you set the EcoSpace and possibly root:

(this.Resources["MyVm"] as ViewModelCodeGen_FirstView.FirstView).SetEcoSpace(_es);
