启动EF4 CF CTP5应用程序时断言失败 [英] Assert Failure when starting EF4 CF CTP5 Application

问题描述

启动应用程序时出现以下错误。

I get the following error when I start my application.

我附加下面的调试器后抛出异常。这是一个
链接到我的解决方案（压缩）。

There's an exception throw after I attach the debugger which is below. Here is a link to my solution (zipped).

我喜欢这里的一些帮助，因为例外错误没有意义，因为所列实体上有一个公共属性。

I'd love some assistance here as the exception error doesn't make sense given that there is a public property of the name on the entity listed.

未处理Sysem.InvalidOperationException消息=外键组件"DivisionId"为不是实体'DivisionInSeason'的已申报财产。验证它是否未从模型中明确排除，并且它是有效的原始属性。

Sysem.InvalidOperationException was unhandled Message=The foreign key component 'DivisionId' is not a declared property on the entity 'DivisionInSeason'. Verify that it has not been explicitly excluded from the model and that it is a valid primitive property.

已修复！

我的OnModelCreating（...）

I had this in my OnModelCreating(...)

       modelBuilder.Entity<TeamInDivision>()
        .HasRequired(u => u.Division)
        .WithRequiredPrincipal()
        .WillCascadeOnDelete(false);

      modelBuilder.Entity<PlayerOnTeam>()
        .HasRequired(u => u.Team)
        .WithRequiredPrincipal()
        .WillCascadeOnDelete(false);
