There is a workaround.

XML

<TextBox Name="MyTextBox"
	 Width="250"
	 Height="60"
	 AcceptsReturn="True"
	 PreviewKeyDown="MyTextBox_OnPreviewKeyDown">
</TextBox>

You can use the PreviewKeyDown event.
In your Event Handler do not forget to get rid of the trailing line feeds by using Trim().

C#

private void MyTextBox_OnPreviewKeyDown(object sender, KeyEventArgs e)
{
	if (e.Key == Key.Enter)
	{
		MessageBox.Show(MyTextBox.Text.Trim());
	}
}
