MakeInternal does not work (ignored & removed if added manually)

I am using 4.50

I see it has been handled in the SStack code …
hover it seems to me that the plugin has not been updated accordingly

in ServiceModelTemplate.txt : MakeInternal does not exists

public class CodegenOptions
bool? MakePartial;
bool? MakeVirtual;
bool? MakeDataContractsExtensible;
bool? InitializeCollections;
bool? AddReturnMarker;
bool? AddDescriptionAsComments;
bool? AddDataContractAttributes;
bool? AddIndexesToDataMembers;
bool? AddResponseStatus;
int? AddImplicitVersion;
string AddDefaultXmlNamespace;

well … very strange I re-opened vsnet and re-loaded the solution and now it works ?!
