Modifying Dynamics 365 Sales Code for Technical Upgrade to Dynamics NAV 2017

  • Cikk

Applies to: Microsoft Dynamics NAV 2017 cumulative update 55 (July 2021) and later

If your solution integrates with Microsoft Dynamics 365 for Sales, and you're upgrading to Dynamics NAV cumulative update 55 (build 30587) or later, you'll have modify some code before you do the upgrade.

Overview

Dynamics NAV cumulative update 55 introduced the following changes will affect the integration:

  • Microsoft .NET Framework 4.6.2 is now required to be installed on the machine where Microsoft Dynamics NAV 2017 Server runs. It should install automatically by the Microsoft Dynamics NAV 2017 installer (setup.exe). Otherwsie, it can be found on the Microsoft Dynamics NAV 2017 installation media (DVD) in the Prerequisites folder. You can also downloaded it from Download .NET Framework 4.6.2.

  • Support for CRM version 8.x has been removed and replaced with CRM SDK version 9.1. The CRM SDK version 9.1 is now part of Dynamics NAV Integration Solution (.zip) found on the installation media (DVD).

  • Microsoft.IdentityModel.Clients.ActiveDirectory version 3.19 is required instead of version 2.28.

The following sections explain how to address these changes.

Make variable declarations version-agnostic

In C/AL code, you'll have to change the version-specific references to CRM version 8 to be version-agnostic. This section describes the changes that you have to make. The following base application objects objects have been identified as containing such explicit version-specific references, which you'll need to change as a minimum. Your application might contain more.

  • Codeunit 5330
  • Table 5330

Variable declaration changes

  • Change:

    DotNet "'Microsoft.Xrm.Sdk, Version=8.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.<class/type>"

    To:

    DotNet "'Microsoft.Xrm.Sdk'.<class/type>”

  • Change:

    DotNet 'Microsoft.Xrm.Tooling.Connector, Version=2.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.<class/type>”

    To:

    DotNet "'Microsoft.Xrm.Tooling.Connector'.<class/type>”

Update Microsoft.IdentityModel.Clients.ActiveDirectory (post-upgrade)

Microsoft.IdentityModel.Clients.ActiveDirectory version 3.19 is provided on the installation media (DVD). It should be installed automatically when you install Dynamic NAV Server. But after upgrade, it's a good idea to verify that you have the correct version in the Dynamics NAV Server installation folder. By default, the folder is C:\Program Files\Microsoft Dynamics NAV\100\Service.

To check the version, search the folder for "Microsoft.IdentityModel.Clients.ActiveDirectory.dll". Open its Properties, and look at the File Version on the Details tab. If the version is not 3.19, copy the Microsoft.IdentityModel.Clients.ActiveDirectory.dll file from the ServiceTier\program files\Microsoft Dynamics NAV\100\Service folder of the installation media (DVD) to your Dynamics NAV Serve installation folder.
