In this blog, I will give you the list of steps to automate SharePoint ADD IN's deployment, using CSOM.

  1. ClientContext cctx = new ClientContext(myurl);
  2. cctx.AuthenticationMode = ClientAuthenticationMode.Default;
  3. cctx.Credentials = new SharePointOnlineCredentials(userName, pwd);
  5. // Get Site Information.
  6. Site site = cctx.Site;
  7. Web web = cctx.Web;
  9. try
  10. {
  11. site.ActivateFeature(sideloadingFeature);
  12. try
  13. {
  14. var appstream = System.IO.File.OpenRead(path);
  15. AppInstance app = web.LoadAndInstallApp(appstream);
  16. cctx.Load(app);
  17. cctx.ExecuteQuery();
  18. }
  19. catch
  20. {
  21. throw;
  22. }
  23. //Disable SideLoadingfeatures
  24. site.DeactivateFeature(sideloadingFeature);
  25. }
  26. catch (Exception ex)
  27. {
  29. Console.WriteLine(string.Format(“Exception!”), ex.ToString());
  30. Console.WriteLine(“Press any key to continue.”);
  31. Console.Read();
  32. }
