Question

我在Visual Studio 2010中构建了一个自定义工作流活动，以便在Dynamics CRM 2013内部部署中使用，我尝试使用插件注册工具注册包含自定义工作流程的程序集，并配置：< strong> Sandbox 和数据库。我花了几个小时努力解决以下异常：

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Exception retrieving custom activity info - Inheritance security rules violated by type: 'TrmIntergration.Workflow.BaseCodeActivity'.

这是活动代码：

using System;
using System.Activities;
using System.Runtime.Serialization;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Workflow;

namespace TrmIntergration.Workflow
{
    public sealed class BaseCodeActivity: CodeActivity
    {        
        [Output("Initiating User")]
        [ReferenceTarget("systemuser")]
        public OutArgument<EntityReference> InitiatingUserReference { get; set; }
        protected override void Execute(CodeActivityContext executionContext)
        {
            IWorkflowContext workflowContext = executionContext.GetExtension<IWorkflowContext>();
            InitiatingUserReference.Set(executionContext, new EntityReference("systemuser", workflowContext.InitiatingUserId));
        }
    }
}

Answer 1

请检查blog。看起来像是同一个问题。

原因是某些旧版外部库不遵循.NET 4.0安全规则。它实际上非常简单的解决方案 - 恢复到.NET 2.0安全性。只需在代码内的任何位置添加以下属性（在using语句之后）：

[assembly: System.Security.SecurityRules(System.Security.SecurityRuleSet.Level1)]

Answer 2

您必须包含system.servicemodel命名空间。
