Usage

In your startup.cs:

public void ConfigureServices(IConfiguration configuration, IWebHostEnvironment environment, IServiceCollection services)
{
    var (connectionString, dbType, allowCache) = configuration.GetDbSettings();
    services.AddSwitchableRelationalDatabase(
        dbType: EntryExtends.IsInUnitTests() ? "InMemory": dbType,
        connectionString: connectionString,
        supportedDbs:
        [
            new MySqlSupportedDb(allowCache: allowCache, splitQuery: false),
            new SqliteSupportedDb(allowCache: allowCache, splitQuery: true),
            new InMemorySupportedDb()
        ]);

    services
        .AddControllersWithViews()
        .AddApplicationPart(typeof(Startup).Assembly);
}

In your appsettings.json:

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

Or:

{
  // sudo docker run -d --name db -e MYSQL_RANDOM_ROOT_PASSWORD=true -e MYSQL_DATABASE=kahla -e MYSQL_USER=kahla -e MYSQL_PASSWORD=kahla_password -p 3306:3306 hub.aiursoft.cn/mysql
  "ConnectionStrings": {
    "AllowCache": "True",
    "DbType": "MySql",
    "DefaultConnection": "Server=localhost;Database=kahla;Uid=kahla;Pwd=kahla_password;"
  }
}

Or:

{
  "ConnectionStrings": {
    "AllowCache": "False",
    "DbType": "InMemory"
  }
}

Simple, isn't it?

Your database project need to be different with your web project, you need the following command to generate migrations:

cd ./Demo.MySql
dotnet ef migrations add Init --context "MySqlContext" -s ../Demo.WebApp/Demo.WebApp.csproj
cd ..

cd ./Demo.Sqlite
dotnet ef migrations add Init --context "SqliteContext" -s ../Demo.WebApp/Demo.WebApp.csproj
cd ..

For more usage, please check the Demo app in the demos folder!
