azure - 如何使用Azure Pipeline构建语言版本 'preview'的.Net Core 5项目？

Question

我有一个在 Visual Studio 2019 预览版中构建的 .Net Core DLL 项目，但当我尝试使用 Azure Pipeline 进行构建时，我收到了一长串与预览版 SDK 中的新语言相关的错误。

这是 csproject 文件的一部分:

<PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>
    <Nullable>enable</Nullable>
    <LangVersion>preview</LangVersion>
    <NeutralLanguage>en-US</NeutralLanguage>
    WarningsAsErrors>NU1605;CS8600;CS8601;CS8602;CS8603;CS8604;CS8610;CS8613;CS8614;CS8618;CS8619;CS8625;CS8629;CS8714</WarningsAsErrors>
    <AllowUnsafeBlocks>true</AllowUnsafeBlocks>
  </PropertyGroup>

这是 Azure Pipeline yml:

# ASP.NET Core
# Build and test ASP.NET Core projects targeting .NET Core.
# Add steps that run tests, create a NuGet package, deploy, and more:
# https://learn.microsoft.com/azure/devops/pipelines/languages/dotnet-core

trigger:
- master

pool:
  vmImage: 'windows-latest'

variables:
  buildConfiguration: 'Release'

steps:
- task: UseDotNet@2
  displayName: 'Install .Net Core SDK'
  inputs:
    packageType: 'sdk'
    version: '5.0.100-preview.4.20258.7'

- task: NuGetAuthenticate@0
  displayName: 'Authenticate'

- script: dotnet build --configuration $(buildConfiguration)
  displayName: 'Build Project'

- task: DotNetCoreCLI@2
  displayName: 'Pack Project'
  inputs:
    command: 'pack'
    packagesToPack: '**/*.csproj'
    versioningScheme: 'off'

- task: DotNetCoreCLI@2
  displayName: 'Push Nuget Package'
  inputs:
    command: 'push'
    packagesToPush: '$(Build.ArtifactStagingDirectory)/*.nupkg'
    nuGetFeedType: 'internal'
    publishVstsFeed: 'my feed key'

以下是错误:

我不知道我在这里做错了什么。为什么在 VS 中构建但 Azure Pipeline 却显示有错误？

这是导致错误的一些代码:这里使用新语言初始化栏是问题

public static IReadOnlyList<byte> GetBars(string data)
{
    // this initialization causes an error
    List<byte> bars = new (((data.Length + 8) * 6) + 1);
    ...
}

返回新的(67, 1);在函数 GetRSEncoder(int codewordSize) 中就是问题所在。

internal class RSEncoder<T> where T : struct, IConvertible
{
    public RSEncoder(int primePoly, int initialExponent)
    {
        ...
    }
}

private static readonly ConcurrentDictionary<int, RSEncoder<short>> RSEncoders = new ConcurrentDictionary<int, RSEncoder<short>>();
private static RSEncoder<short> GetRSEncoder(int codewordSize)
{
    return RSEncoders.GetOrAdd(codewordSize, (size) =>
    {
        switch (size)
        {
            case 6:
                return new (67, 1);

            case 8:
                return new (301, 1);

            case 10:
                return new (1033, 1);

            case 12:
                return new (4201, 1);

            default:
                throw new Exception("Invalid codeword size");
        }
    });
}

我遇到了类似的问题。为了解决这个问题，请在 UseDotNet@2 任务中将 PerformMultiLevelLookup 标志设置为 true 以及 Windows 最新的管道设置。请引用这篇文章:https://learn.microsoft.com/pl-pl/azure/devops/pipelines/tasks/reference/use-dotnet-v2?view=azure-pipelines
