Isn't this message still valid / correct, isn't it? Should we be changing it for this case?

Hmmmm. My understanding was we wanted to stop logging this recommendation for any complex type where we couldn't reliably examine the constructor to verify that they were initializing the property inside it?

The way I had thought this would work was that we would not show this message for top-level objects. We would still show this for arbitrary properties that we couldn't initialize because it is valid for users to initialize it and for us to bind properties on it. That said, this one is a struct so it might have unique characteristics.

I think this exception still makes sense. For a set of types like:
private class Location
{
public PointStruct Point { get; set; }
}
private readonly struct PointStruct
{
public PointStruct(double x, double y)
{
X = x;
Y = y;
}
public double X { get; }
public double Y { get; }
}
We can't examine the Location
constructor to check if Point
is initialized so it doesn't make sense to log that behavior?

Ok, I re-read the message and it works out alrigh - it says you cannot model bind a value type. The part about the ctor is entirely irrelevant here. This seems alright enough, let's get this in.
