为 .Net 5 构建时，DevOps 构建找不到 NetCore.App

Question

我正在尝试运行第一次为 dotnet 5 构建 devops。

这是我的构建管道：

variables:
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Debug'
  projects: '**/Interfaces.Avaloq.BamApi.AzFunc.csproj'
stages:
  - stage: A
    pool:
            name: Hosted Windows 2019 with VS2019
            demands:
            - msbuild
            - visualstudio
    jobs:
      - job: Build
        continueOnError: true
        steps:
        - task: UseDotNet@2
          displayName: 'Install .Net Core SDK'
          inputs:
            packageType: 'sdk'
            version: '5.0.100'
        - script: |
        - task: DotNetCoreCLI@2
          displayName: Restore Functions
          inputs:
            command: restore
            projects: '$(projects)'
            feedsToUse: config
            nugetConfigPath: nuget.config
        - task: DotNetCoreCLI@2
          displayName: Build Functions
          inputs:
            command: build
            projects: '$(projects)'
            arguments: '--configuration $(buildConfiguration)'
        
        - task: DotNetCoreCLI@2
          displayName: Publish
          inputs:
            command: publish
            arguments: '--configuration $(buildConfiguration) --output $(build.artifactstagingdirectory)'
            projects: '$(projects)'
            publishWebProjects: false
            zipAfterPublish: true

这是它试图构建的 cs 项目“Interfaces.Avaloq.BamApi.AzFunc.csproj”：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>
    <AzureFunctionsVersion>v3</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.7" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

dotnet restore 工作正常，但对于构建任务，我收到以下错误：

Error : It was not possible to find any compatible framework version The framework 'Microsoft.NETCore.App', version '3.0.0' was not found.

The following frameworks were found: 5.0.0 at [C:\hostedtoolcache\windows\dotnet\shared\Microsoft.NETCore.App]

我不明白它为什么要查找 v3？

Azure Functions 似乎要到 2020 年底才会支持 dotnet 5。详情请见：https://github.com/Azure/azure-functions-host/issues/6674

为 .Net 5 构建时，DevOps 构建找不到 NetCore.App
