Error Selecting Users In Workflow 2.0

Microsoft Dynamics GPPart of the reason I wrote Microsoft Dynamics GP Workflow 2.0 was that I expected the module to be very popular with clients, and so it has proven. It seems a robust and easy to use solution which is a vast improvement on the old SharePoint based Workflow module.

Recently, after upgrading a client to Microsoft Dynamics GP 2015, I was doing a training session with people from their IT and finance departments, or at least I was trying to. However, when trying to select a manager for the Workflow Type we received the following error:

Microsoft Dynamics GP: [Microsoft][SQL Server Native Client 11.0][SQL Server]A .NET Framework error occurred during execution of user-defined routine or aggregate "GetAssignedUsers": System.IO.FileLoadException: Could not load file or assembly...

Microsoft Dynamics GP

[Microsoft][SQL Server Native Client 11.0][SQL Server]A .NET Framework error occurred during execution of user-defined routine or aggregate "GetAssignedUsers": System.IO.FileLoadException: Could not load file or assembly...

I switched to the demo system on my laptop to continue the training until we took a short break when I did some investigation. I couldn’t see anything apparent on the client’s system so I did a quick online search.

I quickly found this post where someone had the same error and Microsoftie Jonathan Fear recommended running the following SQL:

exec wfDeployClrAssemblies

Once I had run this in SQL Server Management Studio, the error in Workflow Maintenance went away and we were able to complete the training on the clients system.

What should we write about next?
