非常自豪：）

希望这有助于别人。所以，从上面的链接（ http://msdn.microsoft.com/en-US/ data / dn469466 ）有这样一行：

空间类（例如DbGeography，DbGeometry）已从
System.Data.Spatial => System.Data.Entity.Spatial

在我收到此错误之前：

由于IntakeModel.Location类型不可用，因此未加载IntakeModel.FK_Assignee_HomeLocation关系
。
以下信息可能有助于解决以前的错误：
类型ConsoleApplication3.Location上的属性Geo具有
属性类型为System.Data.Spatial.DbGeography '不能将
映射到原始类型。

我只需要在我的Location.cs文件中更改：

  public System.Data.Spatial.DbGeography Geo {get;组; 
 

为此：

  public System.Data.Entity.Spatial.DbGeography Geo {get;组; 
 

解决问题。感谢您发布该链接@Ricky Jones。

I have database with spatial data types. I use database first model and entity framework 6.0.2 and .NET 4.5. When I am trying to use the generated classes I get following error:

Schema specified is not valid. Errors: The relationship 'Name_FK1' was not loaded because the type 'Model.TypeB' is not available. The following information may be useful in resolving the previous error: The property 'Position' on the type 'Data.TypeB' has a property type of 'System.Data.Spatial.DbGeography' which cannot be mapped to a primitive type.

The same error is listed for all tables where I use spatial type. The ‘Name_FK1’ is foreign key relation.

What am I doing wrong?

Thank you for your help.

I fixed it! Very proud of myself :)

Hope this helps somebody else. So, from the link above (http://msdn.microsoft.com/en-US/data/dn469466) there is this line:

Spatial classes (e.g. DbGeography, DbGeometry) have moved from System.Data.Spatial => System.Data.Entity.Spatial

Before I was getting this error:

The relationship 'IntakeModel.FK_Assignee_HomeLocation' was not loaded because the type 'IntakeModel.Location' is not available. The following information may be useful in resolving the previous error: The property 'Geo' on the type 'ConsoleApplication3.Location' has a property type of 'System.Data.Spatial.DbGeography' which cannot be mapped to a primitive type.

I just had to change this in my Location.cs file:

public System.Data.Spatial.DbGeography Geo { get; set; }

To this:

public System.Data.Entity.Spatial.DbGeography Geo { get; set; }

Problem solved. Thanks for posting that link @Ricky Jones.
