无法在管道中建立.Net 5 [英] Can't build .Net 5 in pipeline

问题描述

2周前，我使用.Net 5 RC2创建了一个新的解决方案.我已经将其升级到新版本(5.0.0).我正在尝试创建一个标准的ASP.Net管道来构建它，代理程序池是Azure管道，并且代理规范我已经尝试了Windows-2019和vs2017-win2016.两者都给出如下相同的错误为什么要尝试使用2.1?

I created a new solution 2 weeks ago using .Net 5 RC2. I've upgraded it to the new release (5.0.0). I'm trying to created a standard ASP.Net pipeline to build it, agent pool is Azure Pipelines, and agent specification I've tried both windows-2019 and vs2017-win2016. Both give the same errors as below Why is it trying to use 2.1?

推荐答案

它使用的是Nuget的旧版本.

It was using an older version of Nuget.

我在还原前将其更改为5.x，现在可以正常使用了.

I changed it to 5.x before the restore and it works now.

管道Yaml

- task: NuGetToolInstaller@1
          inputs:
              versionSpec: 4.x.x

然后遇到了由于MSBuild 16.8尚未发布而无法正常工作的问题.更改为dotnet构建，并在其之前放置Use Dotnet 5任务

Then ran into a problem of build not working because MSBuild 16.8 not released yet. Changed to dotnet build and put Use Dotnet 5 task before it
