Dynamics 365 Customer Engagement导入解决方案时出错:Microsoft.Crm.CrmException: Plug-in assembly does not contain the required types or assembly content cannot be updated.

我是微软Dynamics 365 & Power Platform方面的工程师罗勇，也是2015年7月到2018年6月连续三年Dynamics CRM/Business Solutions方面的微软最有价值专家(Microsoft MVP)，欢迎关注我的微信公众号 MSFTDynamics365erLuoYong ，回复373或者20191101可方便获取本文，同时可以在第一间得到我发布的最新博文信息，follow me!

Dynamics 365 Customer Engagement使用解决方案来迁移解决方案，手工导出导入很便捷，也可以用程序来做(程序做法请参考我的博文  为Dynamics 365写一个简单程序实现解决方案一键迁移 )，so easy。导入解决方案时有时候会遇到错误，我的博文 导入解决方案错误及其解决办法 总结了一些，我这里在列一个错误如下：

导入解决方案时出错。 :

如果你用插件注册工具来更新，也会碰到类似错误，我这里截图如下：

这个错误啥原因？我见到的常见原因就是在开发环境有人将插件的SDK 消息步骤 或者自定义工作流活动删除了，在向目标环境(如SIT,UAT,生产环境)导入就会报错。因为目标环境备删除的插件的SDK 消息步骤 或者自定义工作流活动还存在，你要导入的程序集不包括这些系统就会报错。

如何解决？解决办法很简单，找出来这些被删除的插件的SDK 消息步骤 或者自定义工作流活动，使用插件注册工具连接目标环境，将这些被删除的插件的SDK 消息步骤 或者自定义工作流活动也做一个删除就行了。

比如我用于演示的环境，这样眼睛简单以看就知道有一个名称为 CRM.Plugins.PreWorkOrderCreate的插件的SDK 消息步骤被删除了。

解决办法就是右击它，选择【Unregister】操作成功后再导入解决方案或者这个插件程序集。

因为我是Demo环境，注册的插件SDK 消息步骤 或者自定义工作流活动比较少，眼睛一看就看出来了。真实的项目实施中可能比较多，靠眼神比较比较耗时费力。有没有工具来做呢？

答案是有的，XrmToolBox 有这个工具，名称叫 Delta Plugins: Local Assembly vs CRM

使用起来也不难，打开该工具后，点击【Load CRM Assemblies】，然后选择要比较的CRM系统中的程序集，再点击【Load your local assembly】加载下你的程序集，

下面的【CRM Plugins list】和【Assebly Plugins list】就显示了两者的内容，比较容易看出来不同。

还有，我的同事自己写了一个程序，挣得他的同意，我这里将代码贴出来，运行效果如下。

代码如下：

        public int GetHashCode(string obj)
        {
            return obj.GetHashCode();
        }
    }
}

App.config的示例如下，运行之前请修改对应参数，DLL文件需要放到本程序的Bin\Debug文件夹中，IsWorkflow根据需要设置为0或者1，0代表是插件程序集，1代表是自定义工作流活动程序集。

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.2" />
    </startup>
  <appSettings>
    <add key="OrganizationService" value="https://demo.luoyong.me/xrmservices/2011/organization.svc"/>
    <add key="UserName" value="crmadmin@luoyong.me"/>
    <add key="Password" value="Pass"/>
    <!--DLL文件名称-->
    <add key="AssemblyFileName" value="CRM.Plugins.dll"/>
    <!--是否检查工作流-->
    <add key="IsWorkflow" value="0"/>
  </appSettings>
</configuration>

最后有个建议，插件使用的程序集中不要包括自定义工作流活动，反之亦然。
