SSIS 2016 Custom Connection Manager

I`m trying to create a custom connection manager for SQL Server Integration Services 2016, this component already works in SQL Server Integration Services 2012, but, after converting to SQL Server 2016 and changing DLLs of the same version, when I use the connection in Visual Studio, I get an error:

Connection type "XXX" specified for connection manager "XXX" was not recognized as a valid connection manager type. This error is returned when an attempt is made to create a connection manager for an unknown connection type. Check the spelling in the name of the connection type

My code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.IO;
using System.Text;
using System.Xml;
using Microsoft.SqlServer.Dts.Runtime;

namespace TesteCon
      ConnectionType = "COMTest",
      DisplayName = "Test COM Connection",
      Description = "Connection Test COM Services",
      //IconResource = "TesteCon.TesteCon.ico",
      ConnectionContact = "Test",
      UITypeName = "TesteConUI.TesteConUI,TesteConUI,Version=,Culture=neutral,PublicKeyToken=2ce2b8238f2c8ed7")]
    public class TesteCon : ConnectionManagerBase, IDTSComponentPersist
        //Public Key : 2ce2b8238f2c8ed7

        #region Get and Sets
        private const string CONNECTIONSTRING_TEMPLATE_RECEIVE = "MESSAGE=<message>;IDPEDIDO=<idpedido>;TYPE=<type>;";
        private const string CONNECTIONSTRING_TEMPLATE_ENVIO = "MESSAGE=<message>;";

        private string MessageTransaction = "";
        private string IdPedidoTransaction = "";
        private string TypeAction = "";

        [CategoryAttribute("ICOM Connection")]
        [Description("Caminho do arquivo ICOM.ini")]
        public string PathICOMIn { get; set; }

        [Category("ICOM Connection"),
        Description("Persiste conexão ativa")]
        public bool PersistentConnection { get; set; }

        public override string ConnectionString { get; set; }


        #region Creator
        public TesteCon()
            PersistentConnection = false;

        #region Overrides Connections

        public override DTSExecResult Validate(IDTSInfoEvents infoEvents)
            if (!Directory.Exists(PathICOMIn))
                infoEvents.FireError(0, "ICOM Connection", "Caminho informado para a conexão está inválido",
                    string.Empty, 0);
                return DTSExecResult.Failure;

            return DTSExecResult.Success;

        public override void ReleaseConnection(object connection)


        public override object AcquireConnection(object txn)
                ConnectionString = "CODIGORETORNO=000;";
                return "OK";


            catch (Exception)
                ConnectionString = "CODIGORETORNO=-999;";

                return null;

                ConnectionString = "Finally";

            return base.AcquireConnection(txn);

        public void SaveToXML(XmlDocument doc, IDTSInfoEvents infoEvents)
            XmlElement rootElement = doc.CreateElement("TESCONMANAGER");

            XmlAttribute connectionStringAttr = doc.CreateAttribute("ConnectionString");
            connectionStringAttr.Value = ConnectionString;

            XmlAttribute userNameStringAttr = doc.CreateAttribute("PathICOMIn");
            userNameStringAttr.Value = PathICOMIn;

            XmlAttribute urlStringAttr = doc.CreateAttribute("PersistentConnection");
            urlStringAttr.Value = PersistentConnection == true ? "Sim" : "Nao";

        public void LoadFromXML(XmlElement node, IDTSInfoEvents infoEvents)
            // Checking if XML is correct. This might occur if the connection manager XML has been modified outside BIDS/SSDT
            if (node.Name != "TESCONMANAGER")
                throw new Exception(string.Format("Unexpected connectionmanager element when loading task - {0}.", "TESCONMANAGER"));
                // Fill properties with values from package XML
                this.PathICOMIn = node.Attributes.GetNamedItem("PathICOMIn").Value;
                this.PersistentConnection = node.Attributes.GetNamedItem("PersistentConnection").Value == "Sim" ? true : false;
                this.ConnectionString = node.Attributes.GetNamedItem("ConnectionString").Value;


this code doesn't do anything, only returns "OK", just to test.

What I discovered if I execute the Visual Studio with Run64bitRuntime = True, it works, but, if to execute Run64bitRuntime = False, I get the same error:

The connection type "COMTest" specified for connection manager "Test COM Connection" is not recognized as a valid connection manager type. This error is returned when an attempt is made to create a connection manager for an unknown connection type. Check the spelling in the connection type name.

My DLL is copied in both places:

  • C:\Program Files (x86)\Microsoft SQL Server\150\DTS\Connections
  • C:\Program Files\Microsoft SQL Server\150\DTS\Connections

To register a DLL I used:

  • c:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools\gacutil.exe

But I can't execute in mode 64bit, I need 32bit and I don't know if there are other different ways to register 32bit and 64bit.
