Not possible to Substitute.For(new[] { typeof(ISomething) }, null) in 4.3.0 #685
Description
It was changed from:
private static bool HasItems<T>(T[]? array)
{
return array != null && array.Length > 0;
}to
private static bool HasItems<T>(T[]? array) => array?.Length != 0;Those two statements behave differently if array is null. The old code resulted in false but the new code returns true in this case. I don't think that was an intentional change?
Message:
NSubstitute.Exceptions.SubstituteException : Can not provide constructor arguments when substituting for an interface.
Stack Trace:

Changing it to this should fix it:
private static bool HasItems<T>(T[]? array) => array?.Length > 0;
