SystemTarget
[System.Obsolete(Do not call the empty constructor.)]protected SystemTarget() Obsolete parameterless constructor for
SystemTarget. Breaking change: This constructor is obsolete and will throw a System.NotSupportedException if called. It is present only to satisfy certain reflection-based scenarios and should not be used in application code.
If you are using reflection or serialization frameworks that require a parameterless constructor, update your code to use the constructor with parameters: SystemTarget.
