I've got exception while deploying workflow (while activating feature). It cant find types of my custom activities.

I put dll and describing xml to C:\Program Files\Workflow Manager\1.0\Workflow\Artifacts and C:\Program Files\Workflow Manager\1.0\Workflow\WFWebRoot\bin, and dll to the GAC. the server was restarted.

Visual Studio designer toolbox shows my Activities, and I successfully able to put them to surface, configure properties and build project.

What additional configuration steps should I do?

This is error description:

Error occurred in deployment step 'Activate Features': Microsoft.Workflow.Client.ActivityValidationException: Workflow XAML failed validation due to the following errors:

Please, someone, explain the steps needed to deploy custom code activity.

Same problem. Any help?

No help, nobody knows... (

Hi,

Have you tried to deploy a simple workflow with a simple step 'write to history' activity? Please deploy a very simple workflow to ensure workflow is installed/configured properly. Also can you enable workflow logging as described in the link: http://ranaictiu-technicalblog.blogspot.com.au/2013/03/sharepoint-2013-workflow-debugdiagnosis.html. The exception you are getting just says, the workflow service and SharePoint can't communicate, nothing more. Can you please enable the workflow logging and share more details.

Check and verify if you have copied "allowedtypes.xml" to "%ProgramFiles%\Workflow Manager\1.0\Workflow\Artifacts" and "%ProgramFiles%\Workflow Manager\1.0\Workflow\WFWebRoot\bin"

if not create a xml file with following content and copy at same location and follow the steps as below:

<AllowedTypes>
  <Assembly Name="AssemblyName">
    <Namespace Name="NamespaceName">
      <Type>ClassName</Type>
    </Namespace>
  </Assembly>
< /AllowedTypes>

* On the Workflow Manager box you have to:

     - Copy activity assembly to following locations:

          > %ProgramFiles%\Workflow Manager\1.0\Workflow\Artifacts

          > %ProgramFiles%\Workflow Manager\1.0\Workflow\WFWebRoot\bin

     - Add your activity class to the white-list

          > Copy AllowedTypes.xml  also to above two locations

     - Restart Workflow Manager backend service

* On SharePoint box you have to:

     - Copy activity assembly to SharePoint box and install it in the GAC.

     - Reset IIS

what is Workflow manager box and sharepoint box?

Can someone help me here?

SharePoint Box is where SharePoint services are installed and WF Manager box where you installed workflow manager. And if you installed both on same machine, you need to do the both steps on same machine.

I don't know if it is too late, but I was having the same issue even with the latest SharePoint Server 2013 upgrade.

What I did is to compare the "workflow.xaml" file from a SharePoint Designer workflow (after having saved it as a template into the Site Assets library) with the "workflow.xaml" generated from within Visual Studio 2013. What I found and what resolved my issue is to add these two attributes as a part of the Activity element.

xmlns:local

="clr-namespace:Microsoft.SharePoint.WorkflowServices.Activities"

xmlns:mwaw

="clr-namespace:Microsoft.Web.Authoring.Workflow;assembly=Microsoft.Web.Authoring"
