如何使用"BuildManager“从C#代码构建.Net核心应用程序？

Question

我想从C#代码构建.Net核心2.1控制台应用程序。我正在使用BuildManager构建解决方案。

               using (var buildManager = new BuildManager())
                {
                    var bp = new BuildParameters(projectCollection)
                    {
                        Loggers = new List<ILogger>
                        {
                            logger
                        },
                        OnlyLogCriticalEvents = false,
                        DetailedSummary = true,
                        NodeExeLocation = @"C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Professional\\MSBuild\\Current\\Bin\\MSBuild.exe"
                    };

                    var buildRequest = new BuildRequestData(
                        "projectFullPath",
                        globalProperties, null, new[] { "Build" }, null,
                        BuildRequestDataFlags.ReplaceExistingProjectInstance);

                    BuildSubmission submission = null;

                    buildManager.BeginBuild(bp);
                    submission = buildManager.PendBuildRequest(buildRequest);

                    buildResult = submission.Execute();
                    buildManager.EndBuild();

我已经像这样设置了环境变量：

        Environment.SetEnvironmentVariable("MSBuildExtensionsPath", globalProperties["MSBuildExtensionsPath"]);
        Environment.SetEnvironmentVariable("MSBuildFrameworkToolsPath", globalProperties["MSBuildFrameworkToolsPath"]);
        Environment.SetEnvironmentVariable("MSBuildToolsPath32", globalProperties["MSBuildToolsPath32"]);
        Environment.SetEnvironmentVariable("MSBuildSDKsPath", globalProperties["MSBuildSDKsPath"]);
        Environment.SetEnvironmentVariable("RoslynTargetsPath", globalProperties["RoslynTargetsPath"]);

其中globalProperties：

            Path.Combine(programFilesX86, @"Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\msbuild.exe"),
            Path.Combine(programFilesX86,
                @"Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\MSBuild.exe"),
            Path.Combine(programFilesX86, @"Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\MSBuild.exe"),
            Path.Combine(programFilesX86, @"Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe"),
            Path.Combine(programFilesX86, @"MSBuild\14.0\Bin\MSBuild.exe"),
            Path.Combine(programFilesX86, @"MSBuild\12.0\Bin\MSBuild.exe")

现在我有了构建错误。

    Build FAILED.

The name of the task in the project file is the same as the name of the task class. 2.) The task class is "public" and implements the Microsoft.Build.Framework.ITask interface. 3.) The task is correctly declared with <UsingTask> in the project file, or in the *.tasks files located in the "C:\Learn\NetCoreApplicationTestingBuild\NetCoreApplicationTestingBuild\bin\Debug\netcoreapp2.1" directory.

我能够通过安装'Microsoft.Build.Runtime‘nuget包来解决这个问题，这个包解决了缺少的*.overridestasks和*.tasks错误
