AX 2012 R3 AIF WCF Could not load file Microsoft.Dynamics.IntegrationFramework.WebService.Process

(2) ShareShare

Posted on by 4
Hello,
I am working on Microsoft Dynamics AX 2012 R3 and trying to deploy an AIF WCF service (WorkflowActionsAIFServiceGroupHTTP) via System administration → Setup → Services and Application Integration Framework → Web sites.
Initially, I received errors about missing 'bin' directory, which I fixed by creating the bin folder and copying required DLLs. Now, when I browse the service, I get the following error:
---
Server Error in '/WorkflowActionsAIFServiceGroupHTTP' Application.
Parser Error Message: Could not load file or assembly 'Microsoft.Dynamics.IntegrationFramework.WebService.Process, Version=6.3.3000.111, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.
---
Troubleshooting I have done so far:
1. Verified the DLL exists in `C:\inetpub\wwwroot\WorkflowActionsAIFServiceGroupHTTP\bin`.
2. Checked the DLL version – it is 6.3.3000.111.
3. Verified GAC (`C:\Windows\Microsoft.NET\assembly\GAC_MSIL`) contains the same DLL version.
4. Updated bindingRedirect in `web.config` to newVersion="6.3.3000.111".
5. Recycled IIS.
Still getting the same error. It seems like there is a version mismatch somewhere between the DLL in bin and the one expected by AX.
Question:
- How can I ensure the correct version of `Microsoft.Dynamics.IntegrationFramework.WebService.Process` is being loaded?
- Is there a specific AX 2012 R3 hotfix or component reinstall needed to fix this?
- Could this be due to a cached assembly reference?
Any guidance would be appreciated.
