将SharePoint 2010的workflow custom activity升级到SharePoint 2013遇到的问题

前几天需要升级一个自定义的workflow activity，从支持SharePoint 2010的版本，升级到支持SharePoint 2013。 Branch代码出来之后，在VS工程中直接升级，之后编译，部署一切都很顺利，但是在测试的时候出现问题了。

问题是这样的：打开SharePoint Designer 2013，新建一个workflow，在workflow里使用自定义的activity，定义好了之后，保存，然后发布的时候，Designer报了一个错误：

“Errors were found when compiling the workflow. The workflow files were saved but cannot be run.” 具体的信息是“The type or namespace name xxx could not be found (are you missing a using directive or an assembly reference?)”。

我查了一下才知道（请参见点击打开链接），web.config文件中的<authorizedTypes>结构变了，在SharePoint 2013中加了一个子节点<targetFx>，因此需要将自定义的activity的authorizedType加到这个子节点中才行。

以下是2010中的配置文件和2013中的配置文件的对比：

SharePoint 2010：

<System.Workflow.ComponentModel.WorkflowCompiler>  <authorizedTypes>      <authorizedType Assembly="Microsoft.Office.Workflow.Actions, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"Namespace="Microsoft.Office.Workflow.Actions"TypeName="*"Authorized="True" />      <authorizedType Assembly="MyActions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1234567"Namespace="MyActions"TypeName="*"Authorized="True" />  </authorizedTypes>  <authorizedRuleTypes>      <authorizedType Assembly="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>    <targetFx version="v4.0">      <authorizedType Assembly="Microsoft.Office.Workflow.Actions, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"Namespace="Microsoft.Office.Workflow.Actions"TypeName="*"Authorized="True" />      <authorizedType Assembly="MyActions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1234567"Namespace="MyActions"TypeName="*"Authorized="True" />    </targetFx>  </authorizedTypes>  <authorizedRuleTypes>    <targetFx version="v4.0">      <authorizedType Assembly="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>

以下是正确的修改配置文件的代码：

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();
