现在花了几天非常令人沮丧的日子，试图让空间类型 DbGeography 在 Windows Azure 上工作。我有一个带有 Webrole 的 Windows Azure 项目，我在其中使用 DbGeography.Distance() 方法来计算距离。在我的本地计算机上工作就像一个魅力，但一旦发布到 Azure，我得到了例外：
Search spa failed message: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

我已关注博客文章http://alastaira.wordpress.com/2011/08/19/spatial-applications-in-windows-azure-redux-include-denali/添加对 Sql.Server.Types 和 SqlServerSpatial.dll 的引用、msvcp100.dll 和 msvcr100.dll。Thist 实际上与 EF5 和一个 Azure 网站项目一起使用，但现在当我升级到 EF6 和一个云服务项目时不是这样:(
