推荐答案
我向Microsoft技术支持部门支付了500美元，并得到了秘密"答案.在这里，我的同伴编码员...
I paid Microsoft tech support $500 and got the 'secret' answer. Here it is, my fellow coders...
- 打开项目文件夹
- 删除.vs文件夹.
- 删除bin和obj
- 开放式解决方案
- 清洁溶液
- 右键单击解决方案->恢复NuGet程序包
- 打开项目清单代码(不是GUI)
-
更改
IgnorableNamespaces="uap mp">到
IgnorableNamespaces="uap mp rescap">
- Open project folder
- delete .vs folder.
- delete bin and obj
- Open solution
- Clean solution
- Right-click solution -> Restore NuGet Packages
- Open project manifest code (not GUI)
Change
IgnorableNamespaces="uap mp">to
IgnorableNamespaces="uap mp rescap">
替换
<DeviceCapability xmlns:rescap=http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities与
<rescap:Capability Name="broadFileSystemAccess"/>
构建>配置管理器>活动解决方案平台= x64(默认为ARM)
Build > Config Manager > Active solution platform = x64 (it defaults to ARM)
您很高兴.
