Add distinct in the end,

SQL

var PrjNm = (from table2 in objPms.PM_TaskDetails
                 join tabPrj in objPms.PM_ProjectDetails on table2.Proj_Id equals tabPrj.Project_ID
                 where table2.AssignedBy == Convert.ToString(EmplId)
                 select tabPrj.Proj_Title distinct);
