我正在寻找构建一个相当简单的插件来计算使用和剩余的“单位”数量。我有两个自定义实体bc_learninglicences& bc_llbalance，插件在创建时触发，bc_llbalance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，因为我刚刚试图弄清楚如何bc_unitsused继承总和......这个代码构建没有错误。但是 CRM 错误：
插件（执行）的意外异常：LearningLicenses.LearningLicenses：System.IO.FileNotFoundException：无法加载文件或程序集'Microsoft.Xrm.Client，版本= 5.0.9690.2165
我有一个很短的期限来构建它，因为系统即将上线，但是我无法继续处理这个我不明白的错误......
由于我落后于该项目的时间框架，因此此时将不胜感激有关错误或代码/解决方案的帮助。
ps 我是 CRM 2011 开发新手，只有几周/几个项目经验。
