Devops:错误 CS0234:命名空间“Windows"中不存在类型或命名空间名称“ApplicationModel" [英] Devops: Error CS0234: The type or namespace name 'ApplicationModel' does not exist in the namespace 'Windows'

问题描述

我正在尝试为 Windows 通用示例应用程序设置构建管道

哪里

而且它运行正常.

我注意到 Nuget Restore 任务的日志没有错误并且确实报告了

2018-12-16T01:27:31.8700773Z 检查 Microsoft.NETCore.Targets.UniversalWindowsPlatform 5.0.0 与 UAP 的兼容性，Version=v10.0 (win10-x86-aot).2018-12-16T01:27:31.8700831Z 检查 Microsoft.NETCore.Platforms 1.0.0 与 UAP 的兼容性，版本 = v10.0 (win10-x86-aot).2018-12-16T01:27:31.8700878Z 所有包和项目都兼容 UAP，Version=v10.0 (win10-x86-aot).

查看SDK在我机器上的位置

C:Program Files (x86)Windows Kits10References10.0.17763.0Windows.AI.MachineLearning.MachineLearningContract1.0.0.0

我想知道 Nuget 是怎么知道的.事实上，我想知道为什么它在路径中包含机器学习.

[更新]

我按照 Stefan Wick MSFT 的建议将版本更改为 17134 (RS4/1803) 而不是 17763 (RS5/1809)

错误更改为

解决方案

该错误是由于您的应用面向 1809 SDK (v17763)，该 SDK 尚未在构建代理上推出，原因是一些问题.

在它在代理上推出之前，您有两种选择可以解除封锁:

1. 如果您实际上不需要来自 1809 SDK 的任何 API，请以 1803 SDK (v17134) 为目标 - 或
2. 使用这个脚本明确安装17763 SDK 依赖项

一旦有关于 SDK 推出以构建代理的更新，我将更新答案.

I am trying to set up a build pipeline for the Windows Universal Sample Application File Access Project.

The pipeline is using the Azure Pipelines Hosted VS2017 Image

The solution builds when I run it in VS locally.

Package.appxmanifest contains

<TargetDeviceFamily Name="Windows.Universal" MinVersion="10.0.10586.0" MaxVersionTested="10.0.17763.0" />

When the pipeline tries to build the following error appears in the build task log.

Error CS0234: The type or namespace name 'ApplicationModel' 
does not exist in the namespace 'Windows' 
(are you missing an assembly reference?)

The YAML is

resources:
- repo: self
queue:
  name: Hosted VS2017
  demands: 
  - msbuild
  - visualstudio

steps:
- task: NuGetCommand@2
  displayName: 'NuGet restore'


- task: VSBuild@1
  displayName: 'Build solution ***.sln'

The project looks like this on my machine

Where

And it runs correctly.

I notice the log for the Nuget Restore task has no errors and does report

[Update]

Looking at the location on my machine of the SDK

C:Program Files (x86)Windows Kits10References10.0.17763.0Windows.AI.MachineLearning.MachineLearningContract1.0.0.0

I wonder how Nuget is meant to know about that. Indeed I wonder why it has something about MachineLearning in the path.

[Update]

I changed versions to 17134 (RS4/1803) instead of 17763 (RS5/1809) as suggested by Stefan Wick MSFT

The errors changed to

解决方案

The error is due to the fact that your app is targeting the 1809 SDK (v17763), which has not been rolled out on the build agents yet, due to some issues.

Until it has been rolled out on the agents, you have two options to get unblocked:

1. Target the 1803 SDK (v17134) if you don't actually need any APIs from the 1809 SDK - or
2. Use this script to explicitely install the 17763 SDK dependency

I will update the answer once there is an update regarding the SDK rollout to build agents.
