我们需要自动测试我们发布的所有 C#、C++ 和 VB.NET 示例是否能够正确编译。我们需要它来构建所有文件而不列出每个文件。列出每一个意味着如果有人忘记添加一个新的（这将在某天发生），显式调用将错过它。通过遍历所有 .sln 文件，我们总能得到一切。
这样做很容易：
第 2 步需要一种方法来生成 BuildAll.proj 文件。有没有办法告诉 MSBuild 运行子目录下的所有 .sln 文件或创建调用所有底层 .slnl 文件的 BuildAll.proj？
【问题讨论】：
标签： build msbuild subdirectory
此 PowerShell 脚本将还原所有 NuGet 包并在当前目录中递归构建所有解决方案。确保 nuget.exe 和 msbuild 在您的 PATH 中。
$baseDir = (Get-Item -Path ".\" -Verbose).FullName
$items = Get-ChildItem -Path $baseDir -Include *.sln -Recurse
foreach ($item in $items){
nuget restore $item
msbuild $item
}

您可以将以下 PowerShell 用于 .NET Core 项目
$baseDir = (Get-Item -Path ".\" -Verbose).FullName
Write-Host ("Scanning *.sln files in " + $baseDir)
$solutionPaths = Get-ChildItem -Path $baseDir -Include *.sln -Recurse
Write-Host ("Total found: " + $solutionPaths.Count)
foreach ($solutionPath in $solutionPaths) {
Write-Host ("Building => " + $solutionPath)
dotnet build $solutionPath
}

我们找不到任何东西，所以我们编写了一个程序来创建一个 BuildAll.proj，它调用一个目录下的所有 .sln 文件。完整的解决方案在Windward Wrocks（我的博客）。
