Async LINQ ForEach

Async LINQ ForEach

Is it possible to use Async when using LINQ ForEach? Below is the code I
am trying:
using (DataContext db = new DataLayer.DataContext())
{
db.Groups.ToList().ForEach(i => async {
await GetAdminsFromGroup(i.Gid);
});
}
I am getting the error:
The name 'Async' does not exist in the current context
The method the using statement is enclosed in is set to async.
