Usage

This snippet directly configures a PostgreSQL database connection for an Entity Framework Core DbContext using a connection string.

public class MyDbContext : DbContext {
 
  protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) {

     optionsBuilder.UsePostgreSql(@"UserId=postgres;Password=postgres;Host=127.0.0.1;Port=5432;Database=test;Schema=pg_catalog;");
  } 
}

Configuration Using PostgreSqlConnection Instance

using Devart.Data.PostgreSql;
...

public class MyDbContext : DbContext {
 
  protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) {

     var connection = new PostgreSqlConnection();
     connection.Host = "127.0.0.1";
     connection.Port = 5432;
     connection.UserId = "postgres";
     connection.Password = "postgres";
     connection.Database = "test";
     connection.Schema = "pg_catalog";
     optionsBuilder.UsePostgreSql(connection);
  } 
}

   }
}

DbContext Configuration:

public class MyDbContext : DbContext {
 
  protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) {

    IConfigurationBuilder builder = new ConfigurationBuilder().AddJsonFile("appsettings.json");
    IConfiguration configuration = builder.Build();
    optionsBuilder.UsePostgreSql(configuration.GetConnectionString("DefaultConnection"));
