According to CA1062 null checks are required in externally visible methods like this:
public static double GetLongitude(this Location location)
{
if(location is null)
{
throw new ArgumentNullException(nameof(location));
}
return location.Longitude;
}
I have now updated to .net 6.0 and tried to use the parameter null check "!!":
public static double GetLongitude(this Location location!!) => location.Longitude;
But this thrown CA1062 again.
Hope you guys can help me :-)

There's no such operator in C# 10/.NET 6. Parameter null checking is a proposal for the upcoming C# 11 that was eventually postponed due to developer objections in April 2022.
