使用backgroundMediaPlayback功能时，[UWP] App清单验证错误 [英] [UWP]App manifest validation error when using backgroundMediaPlayback capability

问题描述

 

使用  backgroundMediaPlayback功能时，我在生成商店套餐时出现问题，我收到以下错误：

验证错误。错误C00CE014：应用清单验证错误：应用清单必须按照架构有效：

以下是清单的重要部分：

< ;包xmlns =" http：//schemas.microsoft.com/appx/manifest/foundation/windows10"的xmlns：熔点=" HTTP：//schemas.microsoft.com/appx/2014/phone/manifest"的xmlns：UAP = QUOT; HTTP：//schemas.microsoft.com/appx/manifest/uap/windows10"的xmlns：uap3 = QUOT; HTTP：//schemas.microsoft.com/appx/manifest/uap/windows10/3"
IgnorableNamespaces =" uap mp uap3">

............

  <功能>

    < Capability Name =" internetClient" />
$
    < uap3：Capability Name =" backgroundMediaPlayback" />

  < / Capabilities>

..............

当我尝试通过以下方式生成商店包时visual studio（store =>创建app包）我得到了开头描述的错误，并且清单被修改为：

  <功能>

    < Capability Name =" internetClient" />
$
    < Capability Name =" backgroundMediaPlayback"的xmlns = QUOT;" />
$
    < uap3：Capability Name =" backgroundMediaPlayback" />

  < / Capabilities>

上周我的视频工作室2017年更新后，我开始收到此错误。 （我今天有一个新的更新15.1，问题仍然存在......）

如果我通过命令提示生成包，这不会发生.... / p>

任何想法？

解决方案

您好jm.villagra_z，

感谢您报告此问题。我可以在我这边重现这个问题，并且我已经向2017年的Visual Studio报告过了。可能需要一些时间进行研究和测试。感谢你的耐心。

祝你好运，

Hi, 

I'm having problems generating store packages when using the backgroundMediaPlayback capability, i'm getting the following error:

Validation error. error C00CE014: App manifest validation error: The app manifest must be valid as per schema:

Here is the revelant part of the manifest:

<Package xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10" xmlns:mp="http://schemas.microsoft.com/appx/2014/phone/manifest" xmlns:uap="http://schemas.microsoft.com/appx/manifest/uap/windows10" xmlns:uap3="http://schemas.microsoft.com/appx/manifest/uap/windows10/3" IgnorableNamespaces="uap mp uap3">

............

  <Capabilities>
    <Capability Name="internetClient" />
    <uap3:Capability Name="backgroundMediaPlayback" />
  </Capabilities>

..............

When i try to generate the store packages via visual studio (store => create app packages) i get the error described at the begining and the manifest is modified to:

  <Capabilities>
    <Capability Name="internetClient" />
    <Capability Name="backgroundMediaPlayback" xmlns="" />
    <uap3:Capability Name="backgroundMediaPlayback" />
  </Capabilities>

I've started getting this error whitin visual studio 2017 last week's update. (i've got a new update today 15.1 and the problem is still here....)

This doesn't happens if i generate the packages via command promp....

Any ideas?

解决方案

Hi jm.villagra_z,

Thanks for reporting this issue. I can reproduce this issue in my side and I have reported it to the Visual studio 2017. It maybe need some time for research and test. Appreciate your patience.

Best regards,

Breeze
