我正在生成一个 sharepoint 2010 bdc 模型 xml 文件以及来自模型 1st LLBLGen 框架/C# .net 3.5 项目的实体和关联的服务类。当我在部署 BDC 解决方案时突然开始收到此错误时,一切都很顺利;
“在部署步骤‘添加解决方案’中发生错误 178 错误:不能为每个 ILobSystem 对象创建超过‘500’个 IEntity 对象。 ”
使用当前的实体数量,它一直在正常部署(在修改注册表以扩展超时设置之后)。我在 MSDN 中或通过 google 都找不到对 IEntity 对象限制的任何引用,并尝试以各种方式更改生成的 xml 文件以进行测试。如果我删除一个实体,错误会转移到下一个实体的开头。Visual Studio 构建的解决方案很好,只有关于 datetime 数据类型的警告(显然是已知问题)。
我只定义了 59 个实体。其中一些在继承层次结构中,并且模型中表达了许多 FK 关系。我的模型中有太多实体对我来说没有任何意义。我还有很多想补充的。我在每个实体上都包含 EstimatedInstanceCount="10000" 但这似乎没有任何影响。事实上,我相信这是默认设置。模型文件非常大,但我将包含以下单个实体片段以供参考,以了解正在生成的代码。

- 这是一个误导性的错误信息吗?
- 我可以尝试对模型进行哪些更改?
- 是否有任何网站设置会影响这一点?
谢谢你的帮助!
