Windows Azure上的EF 6和空间类型DbGeography [英] EF 6 and spatial type DbGeography on Windows Azure

问题描述

现在花了很多令人沮丧的日子来尝试使空间类型DbGeography在Windows Azure上运行.我有一个带Webrole的Windows Azure项目，在其中使用DbGeography.Distance()方法计算距离.在我的本地计算机上可以正常运行，但是一旦发布到Azure，我会得到一个例外:

Have spent a couple of very frustrating days now trying to get the spatial type DbGeography to work on Windows Azure. I have a Windows Azure project with a Webrole where I use the DbGeography.Distance() method to calculate distances. Works lika a charm on my local computer but once published to Azure I get the exception:

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)

我关注了博客帖子

I have followed the blog post http://alastaira.wordpress.com/2011/08/19/spatial-applications-in-windows-azure-redux-including-denali/ adding reference to Sql.Server.Types and SqlServerSpatial.dll, msvcp100.dll and msvcr100.dll. Thist actually worked with EF5 and an Azure Website project but not now when I upgraded to EF6 and a Cloud service project :(

推荐答案

System.BadImageFormatException表示您正在部署错误版本的本机程序集(x86与x64).

The System.BadImageFormatException means you are deploying the wrong version of the native assembly (x86 vs x64).

我们已经发布了一个NuGet软件包，以使其更容易-请查看此帖子以获取详细信息

We've published a NuGet package to make this easier - check out this post for details http://blogs.msdn.com/b/adonet/archive/2013/12/09/microsoft-sqlserver-types-nuget-package-spatial-on-azure.aspx.
