C# 使用fsutil硬链接创建而不是慢速复制任务加速msbuild

我正在尝试加速我们的构建（csharp、msbuild、.NET3.5）。将副本替换为fsutil硬链接创建

以前，我几乎是通过在sln文件上运行脚本并使dll引用private=false，然后让后期构建事件创建硬链接来实现的。问题是不包括可传递依赖项。因此，我认为我需要引用msbuild中的任务，以获取需要硬链接的可传递依赖项

有什么想法吗

此人尝试了同样的方法，但没有发布最终解决方案

需要明确的是：我想要的是保持单独的bin目录，而不是将文件从一个复制到另一个，以创建从源（引用或依赖项）到目标（当前项目的bin）的硬链接。这要快得多，并且提供与复制大致相同的效果。

您是否尝试定义在ResolveAssemblyReferences目标之后运行的自己的目标？ResolveAssemblyReferences运行后，您应该能够使用@（ReferencePath）项来驱动链接创建。考虑实现SeaPraceReleServices，它在微软.Cuff.Objor只是一个空的占位符供您重写。

< P>这在VS 2010中得到支持。但不是2008年。请参阅UseHardLinksIsFable选项，以便在_CopyFilesMarkedCopyLocal中复制

另请参见，了解上下文

重写_CopyFilesMarkedCopyLocal目标。我们在底部的csproj文件中添加了类似的内容：

（在每个完整的nant构建中，它都会自动添加到文件中，并带有nant任务，因此每个项目都会受益）

我们的新目标文件是：

<Project ToolsVersion="3.5" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <UsingTask TaskName="CopyWithHardlinkOption" AssemblyFile="..\lib\TWBuildOptimization\TW.Hardlinker.dll" /> <!-- ============================================================ _CopyFilesMarkedCopyLocal Overridden in order to allow hardlinking with our custom Copy Task. Hardlinking is a major performance improvement. Sometimes 50% of the time compared to copying. Copy references that are marked as "CopyLocal" and their dependencies, including .pdbs, .xmls and satellites. ============================================================ --> <Target Name="_CopyFilesMarkedCopyLocal"> <CopyWithHardlinkOption SourceFiles="@(ReferenceCopyLocalPaths)" DestinationFiles="@(ReferenceCopyLocalPaths->'$(OutDir)%(DestinationSubDirectory)%(Filename)%(Extension)')" SkipUnchangedFiles="true" UseHardlinksIfPossible="true" OverwriteReadOnlyFiles="$(OverwriteReadOnlyFiles)"> <Output TaskParameter="DestinationFiles" ItemName="FileWritesShareable"/> </CopyWithHardlinkOption> </Target> </Project> 还必须添加以下内容：

// decompiled from 4.0
internal static class TwNativeMethods
{
    [DllImport("kernel32.dll", CharSet=CharSet.Unicode, SetLastError=true)]
    internal static extern bool CreateHardLink(string newFileName, string exitingFileName, IntPtr securityAttributes);
}

// decompiled from 4.0
internal static class FileUtilities
{
    internal static void DeleteNoThrow(string path)
    {
        try
        {
            File.Delete(path);
        }
        catch (Exception exception)
        {
            if (ExceptionHandling.NotExpectedException(exception))
            {
                throw;
            }
        }
    }
}

// decompiled from 4.0
internal static class ExceptionHandling
{
    // Methods
    internal static bool IsCriticalException(Exception e)
    {
        return (((e is StackOverflowException) || (e is OutOfMemoryException)) || ((e is ExecutionEngineException) || (e is AccessViolationException)));
    }

    internal static bool NotExpectedException(Exception e)
    {
        return (((!(e is UnauthorizedAccessException) && !(e is ArgumentNullException)) && (!(e is PathTooLongException) && !(e is DirectoryNotFoundException))) && ((!(e is NotSupportedException) && !(e is ArgumentException)) && (!(e is SecurityException) && !(e is IOException))));
    }

    internal static bool NotExpectedReflectionException(Exception e)
    {
        return ((((!(e is TypeLoadException) && !(e is MethodAccessException)) && (!(e is MissingMethodException) && !(e is MemberAccessException))) && ((!(e is BadImageFormatException) && !(e is ReflectionTypeLoadException)) && (!(e is CustomAttributeFormatException) && !(e is TargetParameterCountException)))) && (((!(e is InvalidCastException) && !(e is AmbiguousMatchException)) && (!(e is InvalidFilterCriteriaException) && !(e is TargetException))) && (!(e is MissingFieldException) && NotExpectedException(e))));
    }
}

谢谢，最后我过度浏览了MsBuild的复制本地任务，以创建硬链接，而不是复制引用的传递闭包。如果它能帮助其他人，我希望它能开源。并计划发布更详细的回复，并标记问题的答案。为什么不设置一个到所有bin文件夹的DEVPATH呢。然后，除了关闭copylocal，您不需要做任何事情。有没有办法强制msbuild将文件（或为此创建硬链接）从\obj\debug移动到\bin\debug而不是复制？@ya23我想\obj下的dll/exe与\bin中的不一样。
