Using PowerShell to create and add class libraries to a solution - powershell

Question

I'm trying to automate some of the tasks I perform on each web project. What I want is a PoSH script that I can run on a new solution that will:
load the solution contained in the scripts current directory.
create new projects for the loaded solution and add them to the solution.
create some classes and add them to each of the projects.
So far I have a simple script (shown below) that finds and opens the local solution file.
$scriptpath = $MyInvocation.MyCommand.Path
$dir = Split-Path $scriptpath
Set-Location $dir
$solution = Get-ChildItem | Where-Object{($_.Extension -eq ".sln")}
if ($solution.Count -eq 0)
{
"Please place this script in the folder containing you solution file."
break;
}
$dteObj = New-Object -ComObject "VisualStudio.DTE"
$dteObj.Solution.Open($solution.FullName)
How can I now create new projects and add them to the solution?

To create a project , call GetProjectTemplate, and then pass the returned template paths to AddFromTemplate.
Try this in Package Manager Console.
#Create a Console Project
$csTemplatePath = $dte.Solution.GetProjectTemplate("ConsoleApplication.zip", "CSharp")
$csPrjPath = "C:\\Projects\\SolutionName\\ConsoleApplication1"
$dte.Solution.AddFromTemplate($csTemplatePath, $csPrjPath, "ConsoleApplication1", 'false')
#Create a C# class
$itemPath = $dte.Solution.GetProjectItemTemplate("Class.zip", "CSharp")
$prj = Get-Project
$prjItem = $prj.ProjectItems.AddFromTemplate($itemPath, "Project.cs")
