Another issue with Newstonsoft.JSON in the Middle Tier:

I get:

InvalidCastException: [A]Anesthesia.AnesthPreference cannot be cast to [B]Anesthesia.AnesthPreference. Type A originates
 from 'Anesthesia19.3, Version=19.3.7281.23673, Culture=neutral, PublicKeyToken=null' in the context 'Default' at
 location 'C:\Users\wjs\Desktop\ODVersions\opendental19.3\opendental19.3\OpenDental\bin\Debug\Anesthesia19.3.dll'.
 Type B originates from 'Anesthesia19.3,Version=19.3.7281.23673, Culture=neutral, PublicKeyToken=null' in the context
 LoadNeither' at location 'C:\Users\wjs\Desktop\ODVersions\opendental19.3\opendental19.3\OpenDental\bin\Debug\Anesthesia.dll'.

Here:

Code: Select all

		public static void Update(AnesthPreference anesthPref, bool toggleAllPrefs) {
			if (RemotingClient.RemotingRole == RemotingRole.ClientWeb) {
				Meth.GetVoid(MethodBase.GetCurrentMethod(),anesthPref,toggleAllPrefs); <---------------
				return;
			}
            string command = "REPLACE INTO anesthpreference(PrefNum,TimeStandard,TimeMilitary,VersionNum,AutoSaveMins,
            +FixToothGrphc,FixPhoneOnRx,SplitNotes,ElimDupNotes,ProcNoteLock,DynChartRefresh,
            +ChartRefInterval,DynApptBookRefresh,AddBackupMenuItem,AddEnhancedMenuItems,ToggleAllPrefs) VALUES('1', '"
            + POut.Bool(anesthPref.TimeStandard) + "'"

            + ", '" + POut.Bool(anesthPref.FixToothGrphc) + "'"
            + ", '" + POut.Bool(anesthPref.FixPhoneOnRx) + "'"
            + ", '" + POut.Bool(anesthPref.SplitNotes) + "'"
            + ", '" + POut.Bool(anesthPref.ElimDupNotes) + "'"
            + ", '" + POut.Bool(anesthPref.ProcNoteLock) + "'"
            + ", '" + POut.Bool(anesthPref.DynChartRefresh) + "'"
            + ", '" + POut.Int(anesthPref.ChartRefInterval) + "'"
            + ", '" + POut.Bool(anesthPref.DynApptBookRefresh) + "'"
            + ", '" + POut.Bool(anesthPref.AddBackupMenuItem) + "'"
            + ", '" + POut.Bool(anesthPref.AddEnhancedMenuItems) + "'"
            + ", '" + POut.Bool(anesthPref.ToggleAllPrefs) + "'" + ")";
			DataCore.NonQ(command);
		}

As a reminder, I have to have multiple versions of my plugin in the OD folder (Anesthesia.dll, Anesthesia 19.2.dll, Anesthesia19.3 dll etc,)

To fix this, you probably will have to make sure that just the Anesthesia19.3.dll is in your bin folder on the Middle Tier server. I believe that when IIS loads an application, it will load every assembly in the bin folder, so having multiple Anesthesia dlls will likely cause problems when it comes to serialization.
