Answer 1

Just Go to Tool-->NuGet Package Manager-->Manager Nuget Package Manager

search for NpgSql and then select your project and click Install

sample Code

public void Demo()
        {
            NpgsqlConnection connection = new NpgsqlConnection();
            connection = d_connection; // your connection string
            connection.Open();              
            NpgsqlCommand cmd = new NpgsqlCommand();
            try
            {
                cmd.Connection = connection;
                cmd.CommandText = "select * from your table name";
                cmd.CommandType = System.Data.CommandType.Text;
                using (var dataReader = cmd.ExecuteReader())
                {
                    while (dataReader.Read())
                    {

                     string answer= dataReader.IsDBNull(0) ? "" : dataReader.GetString(0);

                    }
                    dataReader.Dispose();
                }
            }
            catch (Exception e)
            {
            }
            finally
            {
                cmd.Dispose();
                connection.Dispose();
            }            
        }

Dont use upper case in postgreSql because its case sensitive.
