How to frame linq query with COUNT, GROUP BY and select statement?

Question

I have to form a linq query with select, count and select statement

My table looks like this

Date          Name 
2015-04-25    xxy
2015-04-25    pap
2015-04-25    sms
2014-07-12    bljoe
2014-07-12    olk

I want the result similar to this

Date          Count
2015-04-25      3
2014-07-12      2

My sql query will be like this :

select t.date, COUNT(k.Name)
from table t
group by t.date

But I dont know how my linq query should be :

I tried like this. But it returned exception

var result = (from ka in _db.table
                          group t by new {t.Date} into g

                          select new 
                          {
                              Date = g.Key,
                              Count = g.FirstOrDefault().Name.Count()
                          }).ToList();
