Error enabling Office 365 CDN - Method "GetTenantCdnAllowedFileTypes" does not exist
MicrosoftHi Kiril Iliev,
Only logical reason for this would be that you have SharePoint Online Clinet Components SDK (https://www.microsoft.com/en-us/download/details.aspx?id=42038) installed on your machine where you are using these PowerShell cmdlets. This error is then actually raised by the assembly conflict in your local machine and it's not coming from SharePoint Online.
Challenge with the SDK is that it installs CSOM assemblies to GAC, which then overrides them to be used by the PowerShell cmdlets when they are used in PowerShell session. In general we do NOT recommend using this SDK, rather reference the needed assemblies as a NuGet package (https://www.nuget.org/packages/Microsoft.SharePointOnline.CSOM), so that you'll get the latest and greatest APIs for your solutions.
If you uninstall the SDK from your machine, PowerShell cmdlets will use locally deployed assemblies, whcih should resolve your issue. If this is not the scenario or you'll still have the issue regardless of uninstalling this SDK, there's something else wrong.
Hopefully that solves it.
I have done the following:
- uninstalled the SDK
- restarted the SharePoint Online Management Shell
- Added reference to the DLLs with version 16.1.6323.1200 (latest as of now) via Add-Type -Path "PathToDll" for Microsoft.SharePoint.Client.dll, Microsoft.SharePoint.Client.Runtime.dll and Microsoft.Online.SharePoint.Client.Tenant.dll (I believe that the needed methods would be all in the last assembly, but added the rest of the CSOM assemblies just to be sure)
- Tried to run the script entirely in the Windows PowerShell ISE as"
$securePassword = ConvertTo-SecureString $Password -AsPlainText -Force $cred = New-Object System.Management.Automation.PSCredential -ArgumentList $username, $securePassword Connect-SPOService -Credential $cred -Url $tenantAdminUrl Add-Type -Path "PathToDlls\Microsoft.SharePoint.Client.dll" Add-Type -Path "PathToDlls\Microsoft.SharePoint.Client.Runtime.dll" Add-Type -Path "PathToDlls\Microsoft.Online.SharePoint.Client.Tenant.dll" Set-SPOTenantCdnEnabled -CdnType Public -Enable $true
Still getting Set-SPOTenantCdnEnabled : Method "GetTenantCdnAllowedFileTypes" does not exist.
Thanks,
Kiril

You don't need to reference any DLLs when you are using SPO Management Shell cmdlets, so that part is definitely not needed, but it does not explain the exception what you are seeing, since that would still indicate that a wrong CSOM assembly is loaded from GAC to the execution.
Following part is not needed, since SPO cmdlet's do load the CSOM assemblies automatically. That would be only needed if you would use native CSOM in your scripts.
Add-Type -Path "PathToDlls\Microsoft.SharePoint.Client.dll" Add-Type -Path "PathToDlls\Microsoft.SharePoint.Client.Runtime.dl
l" Add-Type -Path "PathToDlls\Microsoft.Online.SharePoint.Client.Ten ant.dll" 
Microsoft just get the situation worse !
Can't find a definitely working instruction!
The law needs to split the Microsoft in two!

Hi George,
didn't quite get the message completely, but if you are looking for documentation, here's the official documentation in the docs.microsoft.com. Feel free to start up a new discussion in MS Tech Community and cc me in the discussion if you still have other questions or challenges.
All feedback on the documentation and guidance is more than welcome. Thanks for your input advance.
I took another approach and something wierd happened - a console application with the latest PnP Core component NuGet package. Here is a sample code:
Tenant tenant = new Tenant(adminCtx); tenant.SetTenantCdnEnabled(SPOTenantCdnType.Public, true); adminCtx.ExecuteQueryRetry(); var isEnabled = tenant.GetTenantCdnEnabled(SPOTenantCdnType.Public);
adminCtx.ExecuteQueryRetry();
// debug mode -> check isEnabled.Value propertyAt first, it has enabled the public Cdn, but later when I tried to add a public CDN origin to one of my libraries (with the AddPublicCdnOrigin), it threw an exception that the Public CDN was disabled. Running the above code, gave me that the CDN's value was set to false for some reason, regardless if I set it again through the C# code to true.
