c# code converted to vb.net causing an issue - advise please

Hi, 
I am looking to extend the default number of records I can download to a vb.net store app from Azure using mobile services.
I found this below blog that has the code for exactly what I want but when I convert the C# to vb.net, I get an error.
http://www.kevinashley.com/2013/02/retrieving-more-data-from-azure-mobile-services-using-paging/
The error in the below vb.net code is at the line - 'table As MobileServiceTableQuery(Of T)' - gives me this error
'Microsoft.WindowsAzure.MobileServices.MobileServiceTableQuery(Of T)' is not accessible in this context because it is 'Friend'.

Can anyone advise me of what the issue is here.

Thanks for all help.
