Using 3rd party dll (itextsharp) in a custom workflow in Dynamics 365 Online

(0) ShareShare

Posted on by Denisse Luna

I'm trying to use iTextSharp in a custom workflow for Dynamics 365.

I'm using ilmerge to merge my workflow dll with the itextsharp dll.

The merged dll is generated and  uploaded to CRM using Plugin Registration tool, however, when I ran the workflow I get: 

Unhandled Exception: Microsoft.Crm.CrmException: System.Security.SecurityException: Microsoft Dynamics CRM has experienced an error. Reference number for administrators or support: #0406AF5A
at Microsoft.Crm.Sandbox.SandboxCodeUnit.Execute(IExecutionContext context)
at Microsoft.Crm.Workflow.Services.ProxyCustomActivity.Execute(CodeActivityContext executionContext)

I was under the understanding that merging the iTextSharp dll was the way to go in CRM Online. Is there something I might be missing?

Or is it not even possible to use itextsharp on online?

Any help/tip is appreciated.

    Hi Denisse,

     it's throwing a security exception, which usually means there is something in that dll that's not allowed in the sandbox mode. In which case it's, likely, not possible to use it.

     If you have an on-prem instance to test it there, I'd try to do the same without sandbox isolation.. If it works, then it's a sandbox limitation, and, then, it definitely can't be done in the online environment

    Hi Denisse,

    I would agree with Alex and seems to be an issue with the workflow code or the third party assembly which tries to perform an operation that is beyond Sandbox mode. Try to run the code in a console application and if every thing goes well, then it should be something to do with sandbox.

    As an alternate you can move the logic to a WebAPI or WCF service and make use of it!
