Simplified Grid Row & Column Definitions in Xamarin Forms

Now with release for Xamarin.Forms 4.7 column and row definitions have been simplified.
Here is a simplified syntax sample:

<Grid ColumnDefinitions="1*, 2*, Auto, *, 200"
    RowDefinitions="1*, Auto, 35, 24, 30">
</Grid>

old fashioned code is below:

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="1*" />
        <ColumnDefinition Width="2*" />
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="200" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="1*" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="35" />
        <RowDefinition Height= "24" />
        <RowDefinition Height="30" />
    </Grid.RowDefinitions>
</Grid>
