c# - How add multiple rows with one Insert query in EF -

i have list of strings of unknown length. i'm adding them database:

if (somentenovasclas.any()) {     foreach (string item in wsclassificacoes) {         dc.classificacaos.add(new classificacao { descricao = item });     }     dc.savechanges(); } 

but ef generate 1 insert each row:

exec sp_executesql n'insert [dbo].[classificacao]([descricao], [excluido]) values (@0, @1) select [codclassificacao] [dbo].[classificacao] @@rowcount > 0 , [codclassificacao] = scope_identity()',n'@0 varchar(255),@1 bit',@0='mercado',@1=0 go exec sp_executesql n'insert [dbo].[classificacao]([descricao], [excluido]) values (@0, @1) select [codclassificacao] [dbo].[classificacao] @@rowcount > 0 , [codclassificacao] = scope_identity()',n'@0 varchar(255),@1 bit',@0='concorrência',@1=0 go 

i'd know how insert in 1 time ef generate command like:

insert table (column) values ([array[0]]), ([array[1]]), ... 

instead of 1 insert foreach.. ideas?

entity framework isn't meant out of box, looks people have created extensions: https://efbulkinsert.codeplex.com/
