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;
}

查找MSBuild的说明:

PowerShell: &"${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe" -latest -prerelease -products * - required Microsoft. component .MSBuild -find MSBuild\**\Bin\MSBuild.exe CMD: "%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe" -latest -pre - release -products * - required Microsoft. component .MSBuild -find MSBuild\**\Bin\MSBuild.exe

查找VSTest的说明:

PowerShell: &"${env:ProgramFiles(x86)}\Microsoft VisualStudio \Installer\ vvswhere .exe" -latest -pre - release -products * -需要Microsoft. visualstudio . packagegroup . testtools . core -查找Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe CMD: "%ProgramFiles(x86)%\Microsoft VisualStudio \Installer\ vvswhere .exe" -latest -pre - release -products * - required Microsoft. visualstudio . packagegroup . testtools . core -find Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe

(请注意，上面的说明与微软的官方说明略有不同。特别地，我已经包含了-pre - release标志来允许预览和RC安装，以及-products *来检测Visual Studio Build Tools安装。)

这只花了两年多的时间，但最终在2019年，微软听取了我们的意见，并为我们提供了一种找到这些重要可执行文件的方法!如果你安装了Visual Studio 2017和/或2019,vwhere实用程序可以查询MSBuild等的位置。由于vswhere被Microsoft保证位于%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe，因此不再需要引导和路径硬编码。

神奇的是-find形参，它是在2.6.2版本中添加的。您可以通过运行vwhere或检查其文件属性来确定已安装的版本。如果您有较旧的版本，您可以下载最新的版本并覆盖现有的%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe。

Vswhere.exe是一个独立的可执行文件，因此您可以从任何有互联网连接的地方下载并运行它。这意味着您的构建脚本可以检查它们所运行的环境是否设置正确(举个例子)。

如果你已经安装了Chocolatey，你也可以使用相关的vwhere包。

翻了翻登记表，看起来

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\2.0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\3.5
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0

也许是你想要的;打开regedit.exe，看一看。

通过命令行查询(由Nikolay Botev提供)

reg.exe query "HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0" /v MSBuildToolsPath

通过PowerShell查询(每个MovGP0)

dir HKLM:\SOFTWARE\Microsoft\MSBuild\ToolsVersions\

最简单的方法可能是打开PowerShell并进入

dir HKLM:\SOFTWARE\Microsoft\MSBuild\ToolsVersions\

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:

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
