Office 365 pre-provision my site issue with Powershell

Question

I am creating personal sites using powershell csom.

My issue is on below line

$loader = [Microsoft.SharePoint.Client.UserProfiles.ProfileLoader]::GetProfileLoader($ctx)

I get following error.

$loader = [Microsoft.SharePoint.Client.UserProfiles.ProfileLoader]::GetProfileLoader($ctx)

Cannot convert argument "context", with value:

"Microsoft.SharePoint.Client.ClientContext", for "GetProfileLoader" to type "Microsoft.SharePoint.Client.ClientRuntimeContext": "Cannot convert the "Microsoft.SharePoint.Client.ClientContext" value of type "Microsoft.SharePoint.Client.ClientContext" to type "Microsoft.SharePoint.Client.ClientRuntimeContext"."

Answer 1

I was running into the same issues and it turned out I was referencing the wrong DLLs. I was also having issues with CreatePersonalSiteEnqueueBulk not being recognized.

I was referencing the 15 version not the 16 version and also the 16 version I had was out of date. Be sure you are referencing the proper DLL and have the most up to date version. I'm now running 16.0.3104.1200 and these issues went away.
