Question

我希望建立一个相当简单的插件来计算使用的“单位”数量。剩余。我有两个自定义的帖子bc_learninglicences＆amp; bc_llbalance，插件会在创建bc_llbalance时触发，另一个用于更新。

bc_llbalance: Contains
    bc_learninglicense (Look up field on bc_learninglicences / bc_name)
    bc_units (units that are used by this record)

bc_learninglicences: Contains 
    bc_name
    bc_unitsquantity (This is set to the total qty of units)
    bc_unitsused (this needs to inherit the sum of "bc_units" on "bc_llbalance")
    bc_unitsremaining ( simply bc_unitsquantity - bc_unitsused )

好的，所以我已经包含了显然没有完成的代码，因为我一直试图弄清楚如何让bc_unitsused继承总和... 此代码构建没有错误。但CRM错误：

插件出现意外异常（Execute）：LearningLicenses.LearningLicenses：System.IO.FileNotFoundException：无法加载文件或程序集'Microsoft.Xrm.Client，Version = 5.0.9690.2165

我有一个很短的截止日期来构建这个，因为系统即将上线，但我不能继续前进这个我不明白的错误......

此时，对于错误或代码/解决方案的帮助将会受到赞赏，因为我在这个项目的时间框架上落后了。

p.s我是开发CRM 2011的新手，只有几周/几个项目经验。

Answer 1

CRM不使用Microsoft.Xrm.Client，因此不存在于GAC或CRM服务器上的任何位置，它旨在与需要它的任何客户端应用程序一起重新分发。

根本不需要在插件程序集中引用它，所以我会将其删除并查看是否有任何代码引用它。如果是这样，它应该能够被替换为不使用该程序集的等效代码。

Answer 2

有两种方法可以解决这个问题，首先您可能需要检查SDK是否在GAC中可用，但我们在内部使用ILMerge来引入插件所需的所有依赖项。
