在Dynamics CRM 2013中注冊自定義工作流活動

Question

我已經在Visual Studio 2010中構建了一個自定義工作流活動 ，以在Dynamics CRM 2013本地中使用，並且我嘗試使用具有以下配置的插件注冊工具來注冊包含自定義工作流的程序集： Sandbox和Database 。 我花了幾個小時努力解決以下異常：

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'.

這是活動代碼：

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

請檢查此博客 。 看起來是一樣的問題。

原因是某些舊版外部庫不遵循.NET 4.0安全規則。 該解決方案實際上非常簡單–恢復為.NET 2.0安全性。 只需在代碼內的任何位置（在using語句之后）添加以下屬性：

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

Answer 2

您必須包括system.servicemodel命名空間。
