Nice!
But ... using your patch I get without nullable:
{code}
private bool _Visible;
public bool Visible
{
get
{
return _Visible;
}
set
{
__isset.Visible = true;
this._Visible = value;
}
}
{code}
Same with nullable:
{code}
private bool _Visible;
public bool? Visible
{
get
{
return __isset.Visible ? (bool?)_Visible : null;
}
set
{
__isset.Visible = value.HasValue;
if (value.HasValue) this._Visible = value.Value;
}
}
{code}
Couldn't the value be stored as the nullable, effectively combining both the
value and the isset flag into one? That way the conversions now introduced in
the getters could be avoided.
Something like this (not tested!):
{code}
private bool? _Visible;
public bool Visible
{
get
{
return _Visible;
}
set
{
_Visible = value;
}
}
{code}
Maybe if autoprops are mono-comaptible (are they? not sure about that) even
simpler:
{code}
public bool? Visible { get; set;}
{code}

> There should be an option to generate nullable value types for C#.
> If a value is not set, then it would return as null rather than default
> value. If a value is updated to null, then it would become unset.
