I have just implemented Supersource capability in c# but have one small issue.
GetInverse says "Argument 1 must be passed with the 'ref' keyword". SDK doesn't specify this (7.0.2). Every other get works fine using "out". Why does this one require "ref".

public int Inverse
{
get
{
superSource.GetInverse(out _inverse); //-- red error under _inverse
return _inverse;
}
set
{
superSource.SetInverse(value);
}
}

Hello Ian,

Thank you for reporting the inconsistency in the Blackmagic Switchers SDK.

This inconsistency has been confirmed and will be addressed in the future release of the Blackmagic Switchers SDK.
