VB.net SQL Check if Primary key is an identity column

Hi

I use the following VB.net code to check if a column is a primary key.
How do I find if it is an identity column
For example "[ID] bigint identity(1,1) primary key" is an identity column
and "[ID] bigint primary key" is not an identity column


               sSQL = "SELECT column_name "
                sSQL = sSQL & "FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE "
                sSQL = sSQL & "WHERE OBJECTPROPERTY(OBJECT_ID(constraint_name), 'IsPrimaryKey') = 1"
                sSQL = sSQL & "AND table_name = '" & oTableName & "'"

                Dim connection As New SqlConnection(Globals.ThisAddIn.oRIGHT.lblConnectionString.Text)
                Dim cmd As New SqlCommand(sSQL, connection)
                connection.Open()
                Get_Primary_Key = cmd.ExecuteScalar().ToString
                connection.Close()
