我遇到实体框架问题并从数据库检索数据。 我拿到了一张桌子。该表格包含一个具有地理类型的字段。 当我运行我的代码：提供程序未返回DbSpatialServices实例
IEnumerable<Locatie> a = locatiezoeker.Locaties.Where(x => x.siteId == geselecteerdeWebsiteId);
我得到以下错误：
Exception: System.Data.ProviderIncompatibleException Message: The provider did not return a DbSpatialServices instance.

我更新了我的EDMX（其实我再生的话）。我更新了我的NuGet包。我正在运行.NET 4.5。看到我的packages.config的片段
<package id="EntityFramework" version="5.0.0" targetFramework="net45" />
有没有人有任何想法，这是哪里出错？我无法在任何地方找到解决方案。
