Get Licenses of User without using any dll in c#

hi,

   when getting the licenses of user through get-msoluser , i see that the licenses is of type list<UserLicense> . Is there any way to get the details of AccountSKUIds of the license for a particular user without using other dlls in c#. The UserLicense is present inMicrosoft.Online.Administration.Automation.PSModule.dll . 

Thanks,

Satya
