在没有其他工具的情况下，从注册表中批量检索msbuild 15 (Visual Studio 2017)的路径:

set regKey=HKLM\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7
set regValue=15.0
for /f "skip=2 tokens=3,*" %%A in ('reg.exe query %regKey% /v %regValue% 2^>nul') do (
    set vs17path=%%A %%B
)
set msbuild15path = %vs17path%\MSBuild\15.0\Bin\MSBuild.exe

更好的可用工具:

vswhere:定位Visual Studio 2017和更新的安装，参见get msbuild15 path with batch(使用硬编码路径，如上面的代码片段)。 使用Microsoft.VisualStudio.Workload.MSBuildTools安装VisualStudio PowerShell模块

获取最新版本的MsBuild。 最好的方法，对于所有类型的msbuild安装，不同的处理器架构(Power Shell):

function Get-MsBuild-Path
{
    $msbuildPathes = $null
    $ptrSize = [System.IntPtr]::Size
    switch ($ptrSize) {
        4 {
            $msbuildPathes =
            @(Resolve-Path "${Env:ProgramFiles(x86)}\Microsoft Visual Studio\*\*\MSBuild\*\Bin\msbuild.exe" -ErrorAction SilentlyContinue) +
            @(Resolve-Path "${Env:ProgramFiles(x86)}\MSBuild\*\Bin\MSBuild.exe" -ErrorAction SilentlyContinue) +
            @(Resolve-Path "${Env:windir}\Microsoft.NET\Framework\*\MSBuild.exe" -ErrorAction SilentlyContinue)
        }
        8 {
            $msbuildPathes =
            @(Resolve-Path "${Env:ProgramFiles(x86)}\Microsoft Visual Studio\*\*\MSBuild\*\Bin\amd64\msbuild.exe" -ErrorAction SilentlyContinue) +
            @(Resolve-Path "${Env:ProgramFiles(x86)}\MSBuild\*\Bin\amd64\MSBuild.exe" -ErrorAction SilentlyContinue) +
            @(Resolve-Path "${Env:windir}\Microsoft.NET\Framework64\*\MSBuild.exe" -ErrorAction SilentlyContinue)
        }
        default {
            throw ($msgs.error_unknown_pointersize -f $ptrSize)
        }
    }

    $latestMSBuildPath = $null
    $latestVersion = $null
    foreach ($msbuildFile in $msbuildPathes)
    {
        $msbuildPath = $msbuildFile.Path
        $versionOutput = & $msbuildPath -version
        $fileVersion = (New-Object System.Version($versionOutput[$versionOutput.Length - 1]))
        if (!$latestVersion -or $latestVersion -lt $fileVersion)
        {
            $latestVersion = $fileVersion
            $latestMSBuildPath = $msbuildPath
        }
    }

    Write-Host "MSBuild version detected: $latestVersion" -Foreground Yellow
    Write-Host "MSBuild path: $latestMSBuildPath" -Foreground Yellow

    return $latestMSBuildPath;
}

如果你有冒险精神，你也可以在https://github.com/Microsoft/msbuild/releases/上从GitHub获得源代码和MsBuild的最新版本

从MSBuild 2017 (v15)开始，MSBuild现在安装在每个Visual Studio版本下的文件夹中

以下是在我的机器上找到MSBuild.exe的一些例子:

C:\windows\Microsoft.NET\Framework\v2.0.50727\MSBuild.exe  (v2.0.50727.8745  32-bit)
C:\windows\Microsoft.NET\Framework64\v2.0.50727\MSBuild.exe  (v2.0.50727.8745  64-bit)

如果你想在。net 4中使用MSBuild，那么你可以使用下面的PowerShell命令来获取可执行文件的路径。如果您想要2.0或3.5版本，只需更改$dotNetVersion变量。

要运行可执行文件，您需要在$msbuild变量前面加上&。这将执行变量。

# valid versions are [2.0, 3.5, 4.0]
$dotNetVersion = "4.0"
$regKey = "HKLM:\software\Microsoft\MSBuild\ToolsVersions\$dotNetVersion"
$regProperty = "MSBuildToolsPath"

$msbuildExe = join-path -path (Get-ItemProperty $regKey).$regProperty -childpath "msbuild.exe"

&$msbuildExe

本处地点

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\2.0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\3.5

给出可执行文件的位置。

但如果你需要保存任务扩展的位置，它是打开的

%ProgramFiles%\MSBuild
