将应用程序从WP8迁移到WP8.1时缺少程序集 [英] Missing assemblies when migrating app from WP8 to WP8.1
问题描述
我有一个正在运行的WP8应用程序，我正在尝试迁移到WP8.1，但很惊讶看到以下错误的组件丢失：
I have a working WP8 app that I'm trying to migrate to WP8.1, but was surprised to see errors that the following assemblies were missing:
- System.Device（使用System.Device.Location.GeoCoordinate类）
- Microsoft.Phone（利用Microsoft.Phone.UserData.Contact及相关类）
包含的确切错误（加上类似的其他错误）：
The exact errors included (plus similar others):
- 类型或命名空间名称'Phone'不存在于命名空间"Microsoft"（您是否缺少程序集引用？）
- 找不到类型或命名空间名称"Contacts"（您是否缺少using指令或程序集引用？）
当我尝试将新的引用添加到项目时，Assemblies>下的列表框架说已经包含了所有内容，并且在Assemblies>下的列表中扩展名为空。
When I try to add new references for these to the project, the list under Assemblies > Framework says everything is included already, and the list under Assemblies > Extensions is empty.
我发现汇编DLL位于以下位置：
C：\Program Files（x86）\ Reference Assemblies\Microsoft \\ \\ Framework\WindowsPhone\v8.1
I discovered the assembly DLL's in the following location:
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\WindowsPhone\v8.1
我手动添加了对这些文件的引用。 这解决了所有以前的错误，但现在我得到一个构建错误"无法在模块mscorlib.dll中找到类型System.SystemException"，这告诉我可能有一个程序集冲突
某处，但是我没有'触摸了mscorlib程序集。
I manually added references to those files. This resolved all of the previous errors, but now I get a build error "Cannot find type System.SystemException in module mscorlib.dll", which tells me there is probably an assembly conflict somewhere, however I haven't touched the mscorlib assembly.
我觉得我不应该手动添加这些引用，但我没有看到任何其他选项。 有什么想法吗？ 谢谢。
I feel like I shouldn't be adding these references manually, but I didn't see any other option. Any ideas? Thanks.
推荐答案
取代System.Device.Location.GeoCoordinate，你必须使用Windows.Device.GeoLocation
Instead of System.Device.Location.GeoCoordinate you have to use Windows.Device.GeoLocation

Microsoft.Phone.UserData .Contact在Windows Phone 8.1中可用
Microsoft.Phone.UserData.Contact is available in Windows Phone 8.1
