How do I programmatically list all projects in a solution?

Question

How do I programmatically list all of the projects in a solution? I\'ll take a script, command-line, or API calls.

The trick is to choose the right MsBuild.dll. Under VS2017 it is indeed "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\amd64\Microsoft.Build.dll" (Dont use the standard Msbuild ddl in references. Browse to this path)

c#:

var solutionFile =    
SolutionFile.Parse(@"c:\NuGetApp1\NuGetApp1.sln");//your solution full path name
var projectsInSolution = solutionFile.ProjectsInOrder;
foreach(var project in projectsInSolution)
{
   switch (project.ProjectType)
   {
      case SolutionProjectType.KnownToBeMSBuildFormat:
     {
         break;
     }
     case SolutionProjectType.SolutionFolder:
     {
         break;
     }
  }
}

powershell:

Add-Type -Path (${env:ProgramFiles(x86)} + '\Microsoft Visual 
Studio\2017\Professional\MSBuild\15.0\Bin\amd64\Microsoft.Build.dll')

$slnPath = 'c:\NuGetApp1\NuGetApp1.sln'
$slnFile = [Microsoft.Build.Construction.SolutionFile]::Parse($slnPath)
$pjcts = $slnFile.ProjectsInOrder

foreach ($item in $pjcts)
{

    switch($item.ProjectType)
    {
        'KnownToBeMSBuildFormat'{Write-Host Project  : $item.ProjectName}
        'SolutionFolder'{Write-Host Solution Folder : $item.ProjectName}
    }
}
