c# - 加快 MSBuild 构建过程

Question

我的构建过程运行良好，但对于一个非常小的项目来说需要将近 3 秒。

我怎样才能加快构建过程？

日志文件太大，无法发布。请随意询问有关记录器输出的问题，然后我会发布请求的部分。

构建项目的 C# 方法

private void CompileCode()
        {
            using (var buildManager = new BuildManager())
            {
                var result = buildManager.Build(this.CreateBuildParameters(), this.CreateBuildRequest());

                if (result.OverallResult == BuildResultCode.Failure)
                {
                    // Error handling
                    var stringbuilder = new StringBuilder();

                    using (var reader = new StreamReader(NameDebuggerLogFile))
                    {
                        stringbuilder.Append(reader.ReadToEnd());
                    }

                    throw new CompilerException(stringbuilder.ToString());
                }
            }
        }

        private BuildParameters CreateBuildParameters()
        {
            var projectCollection = new ProjectCollection();
            var buildLogger = new FileLogger { Verbosity = LoggerVerbosity.Detailed, Parameters = "logfile=" + NameDebuggerLogFile };
            var buildParameters = new BuildParameters(projectCollection) { Loggers = new List<ILogger>() { buildLogger } };
            return buildParameters;
        }

        private BuildRequestData CreateBuildRequest()
        {
            var globalProperties = new Dictionary<string, string>();
            var buildRequest = new BuildRequestData(FolderPath + NameProjectFile, globalProperties, null, new[] { "Build" }, null, BuildRequestDataFlags.ReplaceExistingProjectInstance);
            return buildRequest;
        }

构建期间收集的记录器输出(由于文件大小，只有最后几行)

Done building project "projectfile.csproj".

编辑:

我希望我可以在这里引用Seva Titov:

Building WPF is really tricky, for example XAML files get re-compiled twice (see MSDN). You cannot easily replicate it with just csc.exe. If you have XAML in your project, you have to use MSBuild. – Seva Titov

这就是我必须坚持使用 MSBuild 的原因。

无论如何，我有一些提高性能的想法:

问题 1:这是我的日志文件中的一个片段，它表示 MSBuild 将在解析依赖项时处理 .winmd、.dll 和 .exe 文件。

AllowedAssemblyExtensions:
    .winmd
    .dll
    .exe

因为我只有 .dll 文件，所以我想禁用 MSBuild 考虑 .winmd 文件，这几乎适用于我所有的依赖项。 (下面的例子)

Primary reference "PresentationCore, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35". Resolved file path is "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\PresentationCore.dll". Reference found at search path location "{TargetFrameworkDirectory}". For SearchPath "{TargetFrameworkDirectory}". Considered "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\PresentationCore.winmd", but it didn't exist.

解决方案:1我不得不修改我的 CreateBuildRequest() 方法:

private BuildRequestData CreateBuildRequest()
{
    var globalProperties = new Dictionary<string, string>();
    // Related to idea 1           
    globalProperties.Add("ExpandSDKAllowedReferenceExtensions", ".dll");
    globalProperties.Add("AllowedReferenceAssemblyFileExtensions", ".dll");
    globalProperties.Add("AllowedReferenceRelatedFileExtensions", string.Empty);
    // Related to idea 2     
    globalProperties.Add("BuildProjectReferences", "false");
    globalProperties.Add("BuildInParallel", "true");
    var buildRequest = new BuildRequestData(FolderPath + NameProjectFile, globalProperties, "4.0", new[] { "Build" }, null, BuildRequestDataFlags.IgnoreExistingProjectState);
    return buildRequest;
}

编辑 2:想法 2:有谁知道如何包含/maxcpucount 或/m 开关来并行构建我的项目？对此有解释MSDN page但我不知道如何将它应用到上面列出的项目文件中

解决方案 2:查看解决方案 1，但变化不大。

编辑 3:经过几个小时的玩耍，我想我将不得不放弃。我看到的唯一选择是总体上减少依赖性。但我稍后会回来讨论这个问题。

Answer 1

要回答您的直接问题，您无能为力加快 msbuild 的速度。如果您的机器使用 SSD，我希望它运行得更快，但这可能不是您正在寻找的解决方案。

我唯一能想到的另一件事是完全停止使用 msbuild。它所做的只是驱动 C# 编译器。那么，为什么要费心使用 msbuild 呢？直接使用C#编译器即可。例如通过 CSharpCodeProvider。
