A ScriptCS script that will clean a Visual Studio project directory of files that I don't need. (Think of it as an ignore file that deletes the actual files).

CleanVS.csx

using System.Diagnostics;

Console.WriteLine("Cleaning current folder and subfolders");
Console.WriteLine();
var toDelete = new [] { "bin","obj","bld","Backup","_UpgradeReport_Files","Debug","Release,ipch","*.mdf","*.ldf","*.suo","Packages","bower_components","node_modules","lib",".vs","artifacts" };

var originalConsoleColor = Console.ForegroundColor;
long cleanedSpace = 0;
var errors = new List<string>();
var currentDir = new DirectoryInfo(Directory.GetCurrentDirectory());

foreach (var srch in toDelete)
{
  Console.Write("{0} ", srch);
  
  var candidates = currentDir.GetFileSystemInfos(srch, SearchOption.AllDirectories);
  
  foreach (var candidate in candidates) 
  { 
    Console.ForegroundColor = ConsoleColor.Red;
    try
    {
      if (candidate is DirectoryInfo) 
      {
        var info = (DirectoryInfo)candidate;

        if (Directory.Exists(info.FullName))
        {
          var size = info.GetFiles("*.*", SearchOption.AllDirectories).Sum(file => file.Length);

          DeleteLongDirectory(info);
          cleanedSpace += size;
        }
      }
      else 
      {
        var info = (FileInfo)candidate;

        var size = info.Length;
        info.Delete();
        cleanedSpace += size;
      }
      Console.Write(".");
    }
    catch (Exception ex)
    {
      errors.Add(ex.Message);
      Console.Write("x");
    }
  }
  Console.ForegroundColor = originalConsoleColor;
  Console.WriteLine();
}

Console.WriteLine();
Console.WriteLine("Cleaned...Saved {0:d}mb", cleanedSpace / 1024 / 1024);
if (errors.Count() > 0)
{
  Console.WriteLine();
  Console.WriteLine("Likely you have problems with long-paths (e.g. node_modules)");
  foreach (var err in errors) Console.WriteLine("Error Occurred: {0}", err);
}

    info.Delete(true);
  }
  catch

    // If delete not working (long paths usually), try RimRaf
    var procInfo = new ProcessStartInfo($"rimraf", $"{info.FullName}")
    {
      UseShellExecute = false
    };

    var proc = Process.Start(procInfo);
    proc.WaitForExit();

  }
