Need to groupby and count with EF

Hi all

this code does what I want

SELECT
    MemberId,
    Action,
    COUNT(*)AS CntFROM#ReportStatsGROUPBY MemberId, ActionORDERBY MemberId

and the result is this

MemberId    Action      Cnt1           change      21create21           deactivate  22           change      42create12           deactivate  1

However, how can I achive it by EF?
