Linq con el grupo al contar

¿Cómo escribo esta consulta en linq (vb.net)?

 select B.Name
 from Company B
 group by B.Name
 having COUNT(1) > 1

Me gusta esto:

from c in db.Company
group c by c.Name into grp
where grp.Count() > 1
select grp.Key

O, usando la sintaxis del método:

Company
    .GroupBy(c => c.Name)
    .Where(grp => grp.Count() > 1)
    .Select(grp => grp.Key);

Para cualquiera que quiera hacer esto en vb (como estaba y no pude encontrar nada)

From c In db.Company 
Select c.Name Group By Name Into Group 
Where Group.Count > 1

La siguiente solución puede ayudarlo.

var unmanagedDownloadcountwithfilter = from count in unmanagedDownloadCount.Where(d =>d.downloaddate >= startDate && d.downloaddate <= endDate)
group count by count.unmanagedassetregistryid into grouped
where grouped.Count() > request.Download
select new
{
   UnmanagedAssetRegistryID = grouped.Key,
   Count = grouped.Count()
};
