sudo dpkg -i packages-microsoft-prod.deb
설치:
sudo apt-get update
sudo apt-get install -y apt-transport-https
sudo apt-get update
sudo apt-get install -y dotnet-sdk-5.0
참조: https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu
User secrets 설치
user-secrets 설치
dotnet tool install dotnet-user-secrets --global
디렉토리 초기화
dotnet user-secrets init
개발 환경에 데이터베이스 ConnectionString 저장
PostgreSQL
저장
dotnet user-secrets set ConnectionStrings:<connection-string> "Server=<host>;Port=<port>;User Id=<User id>;password=<password>;database=<database>"
scaffold 사용 예제
dotnet ef dbcontext scaffold Name=ConnectionStrings:<connection-string> Npgsql.EntityFrameworkCore.PostgreSQL
SQL Server
저장:
dotnet user-secrets set ConnectionStrings:<connection-string> "Data Source=(localdb)\MSSQLLocalDB;Initial Catalog=<database>"
scaffold 사용 예제:
dotnet ef dbcontext scaffold Name=ConnectionStrings:<connection-string> Microsoft.EntityFrameworkCore.SqlServer
dotnet entity framework 설치
dotnet 툴 설치:
dotnet tool install --global dotnet-ef
또는 로컬에 설치:
dotnet tool install dotnet-ef
dotnet 툴 업그레이드:
dotnet tool update --global dotnet-ef
또는 로컬에서 업그레이드:
dotnet tool update dotnet-ef
설치 확인:
dotnet ef

Entity Framework Core .NET Command-line Tools 5.0.7
Usage: dotnet ef [options] [command]
Options:
--version Show version information
-h|--help Show help information
-v|--verbose Show verbose output.
--no-color Don't colorize output.
--prefix-output Prefix output with level.
Commands:
database Commands to manage the database.
dbcontext Commands to manage DbContext types.
migrations Commands to manage migrations.
Use "dotnet ef [command] --help" for more information about a command.
Microsoft.EntityFrameworkCore.Design 패키지 설치:
dotnet add package Microsoft.EntityFrameworkCore.Design
데이터베이스 생성 마이그레이션:
dotnet ef database update InitialCreate
DbContext에 대한 코드와 데이터베이스에 대한 엔터티 유형을 생성.
테이블들에 대해 새 Models에 파일 생성 예제:
dotnet ef dbcontext scaffold "Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -o Models
선택한 테이블에 대해서만 생성 예제:
dotnet ef dbcontext scaffold "Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -o Models -t Blog -t Post --context-dir Context -c BlogContext --context-namespace New.Namespace
Secret Manager tool에 의해 연결하고 생성:
dotnet user-secrets set ConnectionStrings:Blogging "Data Source=(localdb)\MSSQLLocalDB;Initial Catalog=Blogging"
dotnet ef dbcontext scaffold Name=ConnectionStrings:Blogging Microsoft.EntityFrameworkCore.SqlServer
클래스 외부에서 DbContext를 구성하려는 경우 OnConfiguring 메서드의 스캐 폴딩을 스킵. ASP.NET Core 앱은 일반적으로 Startup.ConfigureServices에서 구성
dotnet ef dbcontext scaffold "Server=(localdb)\mssqllocaldb;Database=Blogging;User Id=myUsername;Password=myPassword;" Microsoft.EntityFrameworkCore.SqlServer --no-onconfiguring
참조: https://docs.microsoft.com/en-us/ef/core/cli/dotnet
PostgreSQL 적용
패키지 추가:
dotnet add package Npgsql.EntityFrameworkCore.PostgreSQL
또는 .csproj에 추가:
<Project>
<ItemGroup>
<PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="3.1.3" />
</ItemGroup>
</Project>
DbContext에 정의:
using System.Collections.Generic;
using Microsoft.EntityFrameworkCore;
namespace mynamespace
{
public class MyDbContext : DbContext
{
public DbSet<Blog> Blogs { get; set; }
public DbSet<Post> Posts { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
=> optionsBuilder.UseNpgsql("Host=my_host;Database=my_db;Username=my_user;Password=my_pw");
}
public class Blog
{
public int BlogId { get; set; }
public string Url { get; set; }
public List<Post> Posts { get; set; }
}
public class Post
{
public int PostId { get; set; }
public string Title { get; set; }
public string Content { get; set; }
public int BlogId { get; set; }
public Blog Blog { get; set; }
}
}
ASP.NET core의 경우 Startup.cs에 추가 구성:
public void ConfigureServices(IServiceCollection services)
{
// Other DI initializations
services.AddDbContext<MyDbContext>(options =>
options.UseNpgsql(Configuration.GetConnectionString("MyDbContext")));
}
기존 데이터베이스 사용:
dotnet ef dbcontext scaffold "Host=my_host;Database=my_db;Username=my_user;Password=my_pw" Npgsql.EntityFrameworkCore.PostgreSQL
