When running a Powershell step in a SQL Agent job, the environment is 2.0. Is there a new 3.0 provider for SQL Server? Seems strange that PS 3.0 wasn't either shipped with SQL 2012 or at least that there wasn't a way to update it with a new provider when 3.0 became generally available.
I know you can run a cmdexec step and execute a PS command shell there but that's kind of a kludge in my book.
