For SharePoint 2010 custom activities to work in SharePoint 2013, the “authorizedType” node needs to be defined in a new sub-section “targetFx” under the “authorizedTypes” section. If this is not changed, an error will be encountered: ‘The type or namespace name '?' could not be found (are you missing a using directive or an assembly reference.'
Below is an example of how the authroizedTypes were setup in SharePoint 2010 vs how they should be setup in 2013
SharePoint 2010:
<System.Workflow.ComponentModel.WorkflowCompiler>
<authorizedTypes>
<authorizedTypeAssembly="Microsoft.Office.Workflow.Actions, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"Namespace="Microsoft.Office.Workflow.Actions"TypeName="*"Authorized="True" />
<authorizedTypeAssembly="MyActions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1234567"Namespace="MyActions"TypeName="*"Authorized="True" />
</authorizedTypes>
<authorizedRuleTypes>
<authorizedTypeAssembly="Microsoft.SharePoint.WorkflowActions, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"Namespace="Microsoft.SharePoint.WorkflowActions"TypeName="WorkflowCodeTypeReferenceExpression"Authorized="True" />
</authorizedRuleTypes>
</System.Workflow.ComponentModel.WorkflowCompiler>
SharePoint 2013:
<System.Workflow.ComponentModel.WorkflowCompiler>
<authorizedTypes>
<targetFxversion="v4.0">
<authorizedTypeAssembly="Microsoft.Office.Workflow.Actions, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"Namespace="Microsoft.Office.Workflow.Actions"TypeName="*"Authorized="True" />
<authorizedTypeAssembly="MyActions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1234567"Namespace="MyActions"TypeName="*"Authorized="True" />
</targetFx>
</authorizedTypes>
<authorizedRuleTypes>
<targetFxversion="v4.0">
<authorizedTypeAssembly="Microsoft.SharePoint.WorkflowActions, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"Namespace="Microsoft.SharePoint.WorkflowActions"TypeName="WorkflowCodeTypeReferenceExpression"Authorized="True" />
</targetFx>
</authorizedRuleTypes>
</System.Workflow.ComponentModel.WorkflowCompiler>
Modify the “SPWebConfigModification” code if needed:
var service = SPWebService.ContentService;
var addModification = new SPWebConfigModification();
addModification.Path = "configuration/System.Workflow.ComponentModel.WorkflowCompiler/authorizedTypes/targetFx";
addModification.Name= "authorizedType[@Assembly='MyActions'][@Namespace='MyActions'][@TypeName='*'][@Authorized='True']";
addModification.Owner= "MyActions";
addModification.Sequence= 0;
addModification.Type= SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode;
addModification.Value= @"<authorizedType Assembly=""MyActions""Namespace=""MyActions"" TypeName=""*""Authorized=""True"" />";
service.WebConfigModifications.Add(addModification);
service.Update();
service.ApplyWebConfigModifications();
