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;
}

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)
C:\Windows\Microsoft.NET\Framework\v3.5\MSBuild.exe  (v3.5.30729.8763 32-bit)
C:\Windows\Microsoft.NET\Framework64\v3.5\MSBuild.exe  (v3.5.30729.8763 64-bit)
C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe  (v4.7.2053.0 32-bit)
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe  (v4.7.2053.0 64-bit)
C:\Program Files (x86)\MSBuild\12.0\Bin\MSBuild.exe  (v12.0.21005.1 32-bit)
C:\Program Files (x86)\MSBuild\12.0\Bin\amd64\MSBuild.exe (v12.0.21005.1 64-bit)
C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe  (v14.0.25420.1 32-bit)
C:\Program Files (x86)\MSBuild\14.0\Bin\amd64\MSBuild.exe  (v14.0.25420.1 64-bit)
C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe  (v15.1.1012+g251a9aec17 32-bit)
C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\amd64\MSBuild.exe (v15.1.1012+g251a9aec17 64-bit)
C:\Program Files (x86)\Microsoft Visual Studio\2017\{LicenceName}\MSBuild\Bin\MSBuild.exe (v15.1.1012.6693 32-bit)
C:\Program Files (x86)\Microsoft Visual Studio\2017\{LicenceName}\MSBuild\Bin\amd64\MSBuild.exe (v15.1.1012.6693 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

为https://github.com/linqpadless/LinqPadless/blob/master/build.cmd添加vwhere分支，在我的计算机上运行良好，vwhere分支在我伴侣的计算机上运行良好。 也许，vswhere分支应该作为第一个检查向前移动。

这个powershell方法从多个源获取msBuild的路径。按顺序尝试:

首先使用vwhere(因为Visual Studio似乎有更多最新版本的msBuild)。 C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\MSBuild.exe 如果没有发现尝试注册表(框架版本)。 C:\Windows\ Microsoft.NET \ Framework64 \ v4.0.30319 \ msbuild.exe

Powershell代码:

Function GetMsBuildPath {

    Function GetMsBuildPathFromVswhere {
        # Based on https://github.com/microsoft/vswhere/wiki/Find-MSBuild/62adac8eb22431fa91d94e03503d76d48a74939c
        $vswhere = "${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe"
        $path = & $vswhere -latest -prerelease -products * -requires Microsoft.Component.MSBuild -property installationPath
        if ($path) {
            $tool = join-path $path 'MSBuild\Current\Bin\MSBuild.exe'
            if (test-path $tool) {
                return $tool
            }
            $tool = join-path $path 'MSBuild\15.0\Bin\MSBuild.exe'
            if (test-path $tool) {
                return $tool
            }
        }
    }

    Function GetMsBuildPathFromRegistry {
        # Based on Martin Brandl's answer: https://stackoverflow.com/a/57214958/146513
        $msBuildDir = Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\MSBuild\ToolsVersions\' |
            Get-ItemProperty -Name MSBuildToolsPath |
            Sort-Object PSChildName |
            Select-Object -ExpandProperty MSBuildToolsPath -last 1
        $msBuildPath = join-path $msBuildDir 'msbuild.exe'
        if (test-path $msBuildPath) {
            return $msBuildPath
        }
    }

    $msBuildPath = GetMsBuildPathFromVswhere
    if (-Not $msBuildPath) {
        $msBuildPath = GetMsBuildPathFromRegistry
    }
    return $msBuildPath
}
