Blend cannot generate sample data for many intrinsic types

问题

It looks like Blend (2015) cannot generate sample values for certain data types. The types that failed for me include short and byte. The types that generated sample values are string, int and bool. Has anyone else experienced it and is there a workaround for this limitation?

Example:

The following class doesn't generate correct sample data:

public partial class PointLocation
{
    public byte Number { get; set; }
    public short X { get; set; }
    public short Y { get; set; }
}

Sample data looks like (notice there are no sample values):

<VM:PointLocation>
    <VM:PointLocation.Number>
        <System:Byte/>
    </VM:PointLocation.Number>
    <VM:PointLocation.X>
        <System:Int16/>
    </VM:PointLocation.X>
    <VM:PointLocation.Y>
        <System:Int16/>
    </VM:PointLocation.Y>
</VM:PointLocation>

But if simply change the data type of these properties to int:

public partial class PointLocation
{
    public int Number { get; set; }
    public int X { get; set; }
    public int Y { get; set; }
}

The sample data looks like:

<VM:PointLocation Number="79" X="30" Y="68" />

I have noticed the same thing. You can manually edit the generated sample data and add values yourself.
