Could not load file or assembly 'Newtonsoft.Json

[Lark]

I have a couple of components in a workflow project that are custom from the Rest Generator.  The web service they communicate with returns a json formatted result.  I have three Rest components generated from the one integration library.

These (the workflow and the components) work well in debug but have problems once published.  I see exceptions as per the below.  Sometimes restarting workflow solves the problem but not always.

Has anyone seen this before?  The file C:\Program Files\Symantec\Workflow\Shared\lib\Newtonsoft.Json.dll is present and the workflows work just fine in debug.

The only other thing I have noticed is a warning when I open this project of "Duplicate Class Loaded: Automation.RestBaseComponent" which auto-closes.

Workflow 7.6..4383.487

Ok thanks - adding that library to my integration project seems to have removed the error.

It's an issue with Workflow and which folder it is looking at for the library.

You need to add the library (Newtonsoft.Json.dll) to your Project, like you would a Custom INT.

Or just copy it to the bin directory of the Project (release)

There's a Support Ticket raised (ET 3814272).

Workflow 7.6 Point Fix rollup

Alex did your support ticket ever resolve this?  I'm finding adding that dll to every project to be rather annoying.

[Alex Hedley]

The ticket is still open, there's still a POA for it with Engineering.

[Lark]

Alex did your ticket ever get solved?

[Alex Hedley]

Nothing yet, I think with there being a workaround more pressing issues are being dealt with first.

Workaround: Add this library to project before publishing, in the Libraries tab of the project check Copy Local and check on Publish, then re-publish the project. It will create bin directory inside the deployed project folder along with dll.

I've not tested this with v8.0, have you had a chance?

[Lark]

I've not had a chance with WF 8 either just yet - here's hoping though!
