Question

我正在预订系统。

以下查询

    Reservatie r = (from res in entities.Reservaties
    where (res.datum == date && res.tijdslot == time)
    select res).FirstOrDefault();

给我以下错误

错误54错误2003：EntitySet'Reserveaties' MetadataWorkspace中不存在指定为此MSL的一部分。 ... \ WWW \模型\ xxx.edmx

看起来它找不到我的桌子。

edmx文件正确显示我的数据库，我已经好几次了。我检查了MSL并没有看到什么特别的东西。问题是我没有任何线索在哪里寻找问题。

我的集成N2CMS（dinamico包）可能与此有关吗？（它正在使用nHibernate）

知道从哪里开始？

也许edmx是有帮助的

C-S映射内容下的所有内容都标记为错误。

我得到了“作为此MSL的一部分指定的EntitySet'X'在MetadataWorkspace中不存在。”对于我所有的桌子。

我很无能......

Answer 1

忘记添加MySql.Data.Entity dll的引用...

Answer 2

您最好检查＆lt; edmx：ConceptualModels＆gt; ＆lt; Schema Namespace =＆＃34; ?????＆＃34; .......＆gt;，在.EDMX文件中使用的Complex类型。

它应匹配＆lt; ComplexTypeMapping TypeName =＆＃34; ?????.ComplexTypeName＆＃34; ....＆gt;

它解决了我的问题......
