Enabling SideLoading in SharePoint Online for Non-Developer Site

• Install Windows PowerShell from Windows Management Framework (I installed the Windows Management Framework 3.0).
  
  
• Then install “SharePoint Online Management Shell” Link.

Procedure

• Execute a PowerShell script in any desktop not requiring a SharePoint Server (of course that’s the purpose of SharePoint Online).
  
  
• Be sure you enable “ExecutionPolicy” in the client desktop where your PowerShell will be executed.
  
  
• Open “SharePoint Online Management Shell” with “Run as Administrator” and execute Set-ExecutionPolicy RemoteSigned

• Now execute the PowerShell from “SharePoint Online Management Shell”.
  
  
• The PowerShell script is provided here and also attached to the article.
  
  Code
  
  1. $programFiles = [environment]::getfolderpath("programfiles")
  2. add - type - Path $programFiles '\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.dll'
  3. Write - Host 'Ready to enable Sideloading'
  4. $siteurl = Read - Host 'Site Url'
  5. $username = Read - Host "User Name"
  6. $password = Read - Host - AsSecureString 'Password'
  8. $outfilepath = $siteurl - replace ':', '_' - replace '/', '_'
  10. try {
  11. [Microsoft.SharePoint.Client.ClientContext] $cc = New - Object Microsoft.SharePoint.Client.ClientContext($siteurl)[Microsoft.SharePoint.Client.SharePointOnlineCredentials] $spocreds = New - Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, $password)
  12. $cc.Credentials = $spocreds
  13. $site = $cc.Site;
  15. $sideLoadingGuid = new - object System.Guid "AE3A1339-61F5-4f8f-81A7-ABD2DA956A7D"
  16. $site.Features.Add($sideLoadingGuid, $true, [Microsoft.SharePoint.Client.FeatureDefinitionScope]::None);
  18. $cc.ExecuteQuery();
  20. Write - Host - ForegroundColor Green 'SideLoading feature enabled on site'
  21. $siteurl#Activate the Developer Site feature
  22. } catch {
  23. Write - Host - ForegroundColor Red 'Error encountered when trying to enable SideLoading feature'
  24. $siteurl, ':'
  25. $Error[0].ToString();
  26. }
