CRM 动态插件错误

Question

您好，我在尝试分析我的 CRM 插件时遇到错误。我有一个在我的 Pluign 程序集中引用的外部库，该库使用 Entitt Framewiork 5 从外部 SQL 表中查询数据并将该数据写回 CRM。我使用 ILMerger 合并了我的 Pluin 和 DAL 程序集，效果很好，但现在出现以下错误。

[PluginProfiler.Plugins：PluginProfiler.Plugins.ProfilerPlugin] [01646b5d-8250-e511-815f-bab85315b426：WebCall.Plugin.WebCallTrigger：创建电话呼叫（Profiler）]

插件探查器初始化期间发生异常。 未处理的异常：System.TypeLoadException：覆盖成员时违反了继承安全规则：'System.Data.Entity.Migrations.Design.ToolingException.GetObjectData（System.Runtime.Serialization.SerializationInfo，System.Runtime.Serialization.StreamingContext）'。覆盖方法的安全可访问性必须与被覆盖方法的安全可访问性相匹配。

这是我的插件代码

{
    //private CallHistoryData db = new CallHistoryData();

    /// <summary>

知道为什么会发生此错误，我正在使用 CRM On-Premises，并在数据库中的 Sandbox 下注册插件，版本 2015 和我的实体框架版本是 5.0.0。我还为我的两个程序集提供了相同的默认命名空间，在所有 CRm API 程序集上将 Copy 设置为 local = false，我尝试了各种方法，但我没有想法，请帮忙。

显然，覆盖实体框架方法System.Data.Entity.Migrations.Design.ToolingException.GetObjectData 的自定义方法无法在部分受信任的应用程序域中执行。

但是，即使可以，您仍然无法在沙盒插件中打开数据库连接。

由于您正在为 OnPremise 环境进行开发，因此最好的选择是在完全信任的情况下运行您的代码（即不在沙箱中）。
