How do I perform an insert to database and return inserted identity with Dapper?

I\'ve tried something like this:

string sql = \"DECLARE @ID int; \"

If you're using Dapper.SimpleSave:

 //no safety checks
 public static int Create(object param)
    {
        using (SqlConnection conn = new SqlConnection(GetConnectionString()))
        {
            conn.Open();
            conn.Create((T)param);
            return (int) (((T)param).GetType().GetProperties().Where(
                    x => x.CustomAttributes.Where(
                        y=>y.AttributeType.GetType() == typeof(Dapper.SimpleSave.PrimaryKeyAttribute).GetType()).Count()==1).First().GetValue(param));
        }
    }
