OData缩短的关键谓词支持

我使用来自Microsoft.OData.Core（et al）的ODataLib v7.1.1位构建OData服务。我在使用ODataUriParser.ParsePath（）使用缩短的关键词谓词URL格式时遇到了问题。（相对）URL Company（'Comp1'）/ Customer（1）“引发异常”URI中指定的键数与资源'Test.Customer'的键属性数不匹配“。OData缩短的关键谓词支持

该模型是非常简单的，我不明白为什么这是行不通的。其他格式的网址工作（“Company（'Comp1'）”，“Customer（CompanyId ='COMP1'，CustNum = 1）”）。

我已经将模型构建器代码放在$元以下的输出中。任何帮助，将不胜感激。谢谢！

我想通了。我有相反/主要属性颠倒（更正的代码在下面）。其中一个大辩论（几年前）是箭头应该在实体 - 关系模型中指出RI声明的哪一方面（即哪一方是依赖的）。我必须一直处于那个失败的一方。 ;）

var navCompanyCustomer = company.AddUnidirectionalNavigation(
    new EdmNavigationPropertyInfo() 
    { 
     ContainsTarget = true, 
     Name = "Customer", 
     Target = customer, 
     TargetMultiplicity = EdmMultiplicity.Many, 
     DependentProperties = new[] { companyKey1 }, 
     PrincipalProperties = new[] { customerKey1 } 
    });
