我正在尝试创建一个插件来抓住机会的收入，并总计帐户实体的收入。我正在使用Visual Studio 2010 Professional并使用MS Dynamics CRM 2013 SDK。我一直在关注两个指南来帮助我实现目标，但它们适用于Dynamics CRM 2011.对于CRM 2013没有很多指南，因此我希望使用此CRM 2011指南来获取基本插件并进行修改满足我的需求。

使用这些示例我在Visual Basic 2010上启动了插件，但是当我进行构建/部署时，会出现一些错误。错误1是我似乎无法过去的那个。

1,2 - 您需要添加对microsoft.xrm.sdk.dll和microsoft.crm.sdk.proxy.dll的引用。 How to add reference 你可以在SDK中找到dll。
3-你可以重载“执行”方法。
public void Execute(IServiceProvider serviceProvider)
{
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
}
