C# Entity Framework Join

How can I change the joins to left joins

var query = (from u in db.tblvCenterHostsUnassigneds
                             join cms in db.tblvCenterHostNames on u.HostNameid equals cms.HostNameID
                             join vcdc in db.tblvCenterDataCenters on u.VCDC equals vcdc.DataCenterID
                          select new { u.HostNameid, cms.HostName, vcdc.DataCenterName,u.VCName,u.Tier});

You can use something like:
var query = (from u in db.tblvCenterHostsUnassigneds
                   join cms in db.tblvCenterHostNames on u.HostNameid equals cms.HostNameID
                       into GRP1 from subObj1 in GRP1.DefaultIfEmpty()
                   join vcdc in db.tblvCenterDataCenters on u.VCDC equals vcdc.DataCenterID
                        into GRP2 from subObj2 in GRP2.DefaultIfEmpty()
                  select new { u.HostNameid,u.VCName,u.Tier, subObj1.HostName, subObj2.DataCenterName});

A more readable query is shown below:
var query = (from u in db.tblvCenterHostsUnassigneds
             from cms in db.tblvCenterHostNames
		.Where(cm => u.HostNameid = cm.HostNameID)
                .DefaultIfEmpty() // <== makes join left join              
             from vcdc in db.tblvCenterDataCenters
		 .Where(v => u.VCDC equals v.DataCenterID)
                .DefaultIfEmpty() // <== makes join left join              
	     select new {
			     u.HostNameid, cms.HostName, vcdc.DataCenterName, u.VCName, u.Tier
	    }
);
