If, like me, you create new DotNet projects using the same layout and options; the following script should help.

Type $profile in your Powershell Windows Terminal and edit the file at the path given by putting the following code in:

# ---------- dot net new simple alias for project creation
function Show-Menu {
  param (
      [string]$Title
  )
  Clear-Host;
  Write-Host -ForegroundColor Green "================ $Title ================";

  Write-Host "1: " -NoNewline; Write-Host -ForegroundColor Yellow "C# Console Application";
  Write-Host "2: " -NoNewline; Write-Host -ForegroundColor Yellow "C# Library";
  Write-Host "3: " -NoNewline; Write-Host -ForegroundColor Yellow "C# ASP.Net WebApp";
  Write-Host "Q: " -NoNewline; Write-Host -ForegroundColor Yellow "Press 'Q' to quit";
}

function dotnetnew() {
  param (
      [switch]$Verbose = $false,
      [switch]$OmitTest = $false,
      [string]$Name
  )

  $dir = Get-Location;

  $command = "";
  do {
    $title = "Create new dotnet project";
    if ($Name -ne "") {
      $Title = $Title + ": $($Name)";
    }

    Show-Menu -Title $title;

    $selection = Read-Host "What app do you want to create?";
    switch ($selection) {
      '1' { $command = "console" }
      '2' { $command = "classlib" }
      '3' { $command = "webapp" }
    }
  } until ($selection -eq 'q' -or $command -ne '');
  
  if ($selection -eq 'q') {
    Write-Host;
    Break;
  }

    $Name = Read-Host "What name do you want to give this '$($command)' project?";

Set-Alias dn -value "dotnetnew"

Then all you need to do is type dn and you get some simple options to create a basic C# console, library or webapp project including a tests project.

You can also use the command line parameters to bypass some of the options:

# Create project without an MSTest project
dn -Name "MyProject" -OmitTest

# Create project and output verbose logging
dn -Name "MyProject" -Verbose
