DBTools

DbTools are Aiursoft's common database tools. It contains a lot of useful database tools for developers.

Installation

To install Aiursoft.DbTools to your project from nuget.org:

dotnet add package Aiursoft.DbTools

Usage

Easier to register DbContext:

SQLite

var services = new ServiceCollection();
services.AddAiurSqliteWithCache<MyDbContext>("Data Source=app.db");

var built = services.BuildServiceProvider();
var context = built.GetRequiredService<MyDbContext>();

SQL Server

var services = new ServiceCollection();
services.AddAiurSqlServerWithCache<MyDbContext>("Server=(localdb)\\mssqllocaldb;Database=DebugTrusted_Connection=True;MultipleActiveResultSets=true");

var built = services.BuildServiceProvider();
var context = built.GetRequiredService<MyDbContext>();

Easier to update database:

var hostBuilder = Host.CreateDefaultBuilder();
hostBuilder.ConfigureServices(services => 
    services.AddAiurSqliteWithCache<MyDbContext>(@"DataSource=app.db;Cache=Shared")
);
var host = hostBuilder.Build();

// Now update:
await host.UpdateDbAsync<MyDbContext>(UpdateMode.CreateThenUse);

Switchable database

Supports:

• Sqlite
• MySql
• InMemory

First, install the package:

dotnet add package Aiursoft.DbTools.Switchable

In your appsettings.json:

{
  // Database.
  "ConnectionStrings": {
    "AllowCache": "True",
    "DbType": "Sqlite",
    "DefaultConnection": "DataSource=app.db;Cache=Shared"
  },
}

In your startup.cs:

var connectionString = configuration.GetConnectionString("DefaultConnection");
var dbType = configuration.GetSection("ConnectionStrings:DbType").Get<DbType>();
var allowCache = configuration.GetSection("ConnectionStrings:AllowCache").Get<bool>();
services.AddDatabase<MyDbContext>(connectionString, dbType, allowCache);

Tips

If your database project is different with your web project, you may need the following command to generate migrations:

cd ./DatabaseProject
dotnet ef migrations add MigrationName --context YourContext --output-dir Migrations --startup-project ../WebProject
dotnet ef database update --context YourContext
