Error:
"Failed compiling 'AutoPurge.cs': 1. 'ulong' does not contain a definition for 'userid' and no accessible extension method 'userid' accepting a first argument of type 'ulong' could be found (are you missing a using directive or an assembly reference?) [CS1061] (AutoPurge 52 line 429) Requested 'AutoPurge' for compilation Failed compiling

 The error says 'ulong' does not contain a definition for 'userid'. This means that whatever authorizedPlayer is, it's being treated as a ulong type, not an object. This means authorizedPlayer is a ulong. So the simplest fix is just to remove .userid entirely:

Fix is to replace line 429-431 with this: removing .userid

foreach (var authorizedPlayer in privilege.authorizedPlayers)
{
    if (!CanPurgeUser(authorizedPlayer.ToString(), timestamp))  // REMOVED .userid
        return false; // We CANNOT purge an authorized player
}

... not working, can u upload the complete fixed .cs file.

this begins on line 427, not 429

foreach (var authorizedPlayer in privilege.authorizedPlayers)
{
    if (!CanPurgeUser(authorizedPlayer.ToString(), timestamp))  // REMOVED .userid
        return false; // We CANNOT purge an authorized player
}

Delete from the line: userid fixed it for me. Thanks @RuthlessToothless
