the .net interop type cannot be used in code for the classic

iperutility

Hello,

I had made a DLL in C#, easy, and put them under "C:\Program Files (x86)\Microsoft Dynamics NAV\60\Service\Add-ins".

The problem is :

1) I had declared a global variable DotNet of my DLL
2) I had Implemented the global variable
3) I had compiled my codeunit without error

but when I ran my codeunit, those got me this error : the .net interop type cannot be used in code for the classic.

C/AL code in form

sgatePXY := sgatePXY.SGATEProxy;

this is my DLL

using System;
using System.Collections.Generic;
using System.Text;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
using System.Xml;

namespace ClassLibrarySGATE
{

ProxySgate = new SgateWebService();
XDom = new XmlDataDocument();
// Invio i certificati tramite il collegamento proxy web senza doverli registrare sul pc o server
ProxySgate.ClientCertificates.Add(X509Certificate.CreateFromCertFile(pathCertificati + "SGATE.cer"));
ProxySgate.ClientCertificates.Add(X509Certificate.CreateFromCertFile(pathCertificati + "GeoTrustPCA.cer"));
ProxySgate.ClientCertificates.Add(X509Certificate.CreateFromCertFile(pathCertificati + "GeoTrustEV.cer"));
ProxySgate.ClientCertificates.Add(new X509Certificate(pathCertificati + username, password));
ProxySgate.Timeout = 360 * 1000;
return false;
}

public tipoRispostaPresaInCaricoLotto InvokePresaInCaricoLotto(tipoRichiestaPresaInCaricoLotto request, int tentativo)
{
result = null;
try
{
result = ProxySgate.PresaInCaricoLotto(request);
}
catch
{
if (tentativo < 5)
result = InvokePresaInCaricoLotto(request, tentativo + 1);
}
return result;
}

{
if (string.IsNullOrEmpty(result.lottoMessaggi.idLotto))
return result.lottoMessaggi.idLotto;
else
return "KO";
}

public tipoRichiestaPresaInCaricoLotto GeneraRequestRichiestaLotto(string requestXML)

So I guess you are running the code by means of a classic client ...
Indeed you can develop the code (it will compile), but the classic runtime cannot execute it. It can only be executed in the 3-tier setup, so using a RTC (and service tier).
If the code is both to run on classic and RTC you have to check whether it's running on either of them using the ISSERVICETIER function to determine that .Net Interop code will be executed only when ISSERVICETIER = TRUE.
