Data Upgrade ax12 to d365 missing dll

Posted on by Calleb Malinoski

I'm performing the data upgrade process within a VHD pointing to a database. While executing the process, I'm stuck on step 3. I get the following error about a missing DLL. I couldn't find anything related. All .NET versions are up to date.

Log level - Error | Inner Exception: System.IO.FileNotFoundException: Could not load file or assembly 'System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.

As far as I know, it's a .NET Core library and therefore it can't be used in F&O, which is built on .NET Framework, not .NET Core. I guess you make a mistake when upgrading your code and added a reference to a .NET Core assembly. It's now trying to locate .NET Core runtime assemblies, which can't succeed.

Hi CU04092016-0,

System.Private.CoreLib.dll is a part of the DevToolsService component and sits under DevToolsService\Code\DebuggerProxy. Looks like the DevToolsService is corrupted or needs a re-provisioning.

A few questions:

1. Are you able to build models under Visual Studio?

2. Do you see any DB Sync issues?

3. Is this a Cloud based VHD or an On-Premise VHD?

Hope this helps. Happy to answer questions, if any.

Can you please clarify what you were doing when you got the error? We are bringing various ideas but we're merely guessing what you're doing, such as whether you're trying to debug code.

The stack trace shows that the assembly is trying to being found in PackagesLocalDirectory, which I understood as a problem with X++ packages. But it might also have something to do with the Visual Studio extension, as Navtheen suggests.

I am using a VHD pointing to my database, following the documentation below: https://learn.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/migration-upgrade/on-prem-upgrade-2012.

The problem is happening after running

.\AXUpdateInstaller.exe execute -runbookid="MajorVersionDataUpgrade-runbook"

In step 3 at this point.
Failed operation step '/DataUpgrade/PreReqs/AdditiveDbSync'

The first problem I had was with

Log level - Error | Inner Exception: System.IO.FileNotFoundException: Could not load file or assembly 'System.ValueTuple, Version=4.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.
File name: 'System.ValueTuple, Version=4.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'

I copy/paste the dll from a dotnet package, then I got the PrivaveCoreLib problem, but the main problem is all that ddl's missing.

Well, it looks like your environment doesn't have the correct version installed; trying to fix it by copying individual files doesn't sound like a good approach to me.

First of all, are you sure that you're following the right documentation page? Do you an F&O environment on-premises? Note I don't mean a VHD; this is about a production environment hosted an a set of your own servers, with Service Fabric and such things. If not, the page you need is likely Upgrade from AX 2012 - Data upgrade in development environments. If you don't have an on-premises environment, the whole process at Data upgrade process for AX 2012 to Dynamics 365 Finance + Operations (on-premises) doesn't apply to you.

By the way, you didn't mention anything about code upgrade. Have you completed it or is it OK for you to lose all data related to customizations?

I created a new cloud hosted environment, for this purpose, I've been following these steps:

Upgrade from AX 2012 - Data upgrade in development environments - Finance & Operations | Dynamics 365 | Microsoft Learn

I skipped code upgrade, because for this purpose It wont be needed

But running from begginig, I got the same error

System.IO.FileNotFoundException: Could not load file or assembly 'System.ValueTuple, Version=4.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.

After I created the new environment, I used the same database I was using, removed the .bak and restored it.

Please give us more details. What is the version of F&O in your cloud-hosted environment. Which package are you trying to install? Do I understand correctly that it's failing at step 10 when running AXUpdateInstaller.exe execute? Can you share the whole log file, please?

Hi,

I'm using a CHE in version 44. I'm using the same dataupgrade package available in the shared assets library for version 44.
I ran the prerequisites in the AX12 environment, exported the database, and imported it into my CHE. The DLL error occurred in step 3.

I opened a ticket with Microsoft and they gave me a command to copy the missing DDL from one folder to another.

#Edit the Drive details below (C: for VHD, K: normally for CHEs)

Copy-Item -Path "C:\AOSService\webroot\Bin\System.ValueTuple.dll" -Destination "C:\AOSService\PackagesLocalDirectory\bin" -Force

But I got the following error:

This is often an indication that other memory is corrupt. at gopts(Int32 , Char** ) at Microsoft.Dynamics.AX.AOS.StartupInternal(String[] Arguments) at Microsoft.Dynamics.AX.AOS.Startup() at Microsoft.Dynamics.AX.AosConfig.?A0x4463d7bd.GetAosConfig() at Microsoft.Dynamics.AX.AosConfig.Config.InitInternal() at Microsoft.Dynamics.AX.AosConfig.Config.InitOnce(Boolean isOfflineMode) at Microsoft.Dynamics.AX.Framework.Database.Tools.LegacyCodepath.StartAosCode(SyncOptions syncOptions, String sqlConnectionString, IMetadataProvider metadataProvider) at Microsoft.Dynamics.AX.Framework.Database.Tools.LegacyCodepath.ExecuteWithinAOS(SyncOptions syncOptions, String sqlConnectionString, IMetadataProvider metadataProvider, Func`1 func, Action`1 errorHandler) at Microsoft.Dynamics.AX.Framework.Database.Tools.LegacyCodepath.RunFullTableSync(SyncOptions syncOptions, String sqlConnectionString, IMetadataProvider metadataProvider) at Microsoft.Dynamics.AX.Framework.Database.Tools.SyncEngine.AdditiveAllTableSync() at Microsoft.Dynamics.AX.Framework.Database.Tools.SyncEngine.AdditiveTableSync() at Microsoft.Dynamics.AX.Framework.Database.Tools.SyncEngine.RunSync() at Microsoft.Dynamics.AX.Framework.Database.Tools.SyncEngine.Run(String metadataDirectory, String sqlConnectionString, SyncOptions options) at Microsoft.Dynamics.AX.Framework.Database.SyncEngineMain.Sync(Parameters parameters) at Microsoft.Dynamics.AX.Framework.Database.SyncEngineMain.Main(String[] args) Failed operation step '/DataUpgrade/PreReqs/AdditiveDbSync' Process 'C:\AosService\PackagesLocalDirectory\bin\SyncEngine.exe' failed with exit code -2146232797; see error logs for details. at Microsoft.Dynamics.Servicing.DataUpgrade.Operations.Operation.RunProcess(String fileName, ArgumentsBuilder args) at Microsoft.Dynamics.Servicing.DataUpgrade.Operations.OperationStep.Execute()

I've been stuck at the same step for 2 weeks now. The support call with Microsoft hasn't been very helpful. I'm thinking of using an older version of the d365 environment to test.

I've attached the log file too.

It seems that the DB sync fails because the AOT can't start. Unfortunately, this is all kernel code that we can't even look at. Microsoft should address it; it's a pity that the support sucks so much.
