Getting started

ConsoleApp

public static void Main(string[] args)
{
    var configuration = ConfigurationBuilderBuilder.Create<Program>(args).Build();
    var defaultConnectionString = configuration.GetConnectionString("DefaultConnection");
    Console.WriteLine($"[TRACE] ConnectionString: {defaultConnectionString}");
}

Full API support

var initConfig = new ConfigurationBuilder().Build();
IConfigurationRoot configuration = new ConfigurationBuilderBuilder()
    .WithConfiguration(initConfig)
    .WithInMemory(new Dictionary<string, string>{ ["Key:Sub"] = "Value" })
    .WithBasePath("C:/App/bin")
    .WithCurrentDirectory()
    .WithBaseDirectory()
    .WithAppSecrets<Program>()
    .WithAppSecrets(typeof(Program).Assembly)
    .WithAddConfiguration(cb => cb.AddIniFile("appsettings.ini", optional: true, reloadOnChange: true))
    .WithEnvironment("Staging")
    .WithCommandLines(args)
    .Build();

Order of Precedence when Configuring

  • Reference

https://devblogs.microsoft.com/premier-developer/order-of-precedence-when-configuring-asp-net-core/

https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/#default-configuration

  • Order of Precedence
  1. Host configuration from environment variables by prefix DOTNET_ and ASPNETCORE_
  2. Chanined configuration (if any)
  3. In memory configuration (if any)
  4. appsettings.json using the JSON configuration provider
  5. appsettings.EnvironmentName.json using the JSON configuration provider
  6. Other extra configuration sources
  7. App secrets when the app runs in the Development environment
  8. Environment variables using the Environment Variables configuration provider
  9. Command-line arguments using the Command-line configuration provider

BasePath of configuration files

The application binary folder is default basePath for appsettings.json, appsettings.Production.json,etc. In case want to change current directory as basePath:

var configuration = new ConfigurationBuilderBuilder()
    .WithCurrentDirectory()
    .Build();

Environment name

Production environmentName by default if no host environmentName configuration

ConfigurationBuilderBuilder will detect EnvironmentName by add configuration environment variables with prefix DOTNET_ and ASPNETCORE_. If no environment variable set, Production will use by default. Example of environment variables:

ASPNETCORE_ENVIRONMENT = Development
DOTNET_ENVIRONMENT = Staging

Specifying environmentName during build configuration

Sometime, we cannot set the environmentName using environment variable, or we need different environment configuration build lik in unit test project, we can specific the environmentName.

var configuration = ConfigurationBuilderBuilder.Create<ConfigurationBuilderBuilderTest>()
    .WithEnvironment("Testing")
    .Build();

Add extra configuration sources

var configuration = ConfigurationBuilderBuilder.Create<Program>()
    .WithAddConfiguration(cb => cb.AddIniFile("appsettings.ini", optional: true, reloadOnChange: true))
    .WithAddConfiguration(cb => cb.AddXmlFile("appsettings.xml", optional: true, reloadOnChange: true))
    .Build();

Or

var configuration = ConfigurationBuilderBuilder.Create<Program>()
    .WithAddConfiguration(
        cb => cb.AddIniFile("appsettings.ini", optional: true, reloadOnChange: true)
            .AddXmlFile("appsettings.xml", optional: true, reloadOnChange: true)
    )
    .Build();

ConnectionStringManager load from Configuration with database provider information

Reference at https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?#connection-string-prefixes

Support provider

public enum DbProviders
{
    Custom,
    SQLServer,
    PostgreSQL,
    MySQL,
}

List of supported provider name

SQLServer
Mssql
SQLAzure
System.Data.SqlClient

Configuration appsettings.json or environment

{
  "ConnectionStrings": {
    "DefaultConnection": "Server=localhost;Database=dbname;Integrated Security=True;",
    "DefaultConnection_ProviderName": "System.Data.SqlClient",
    "BlogConnection": "AccountEndpoint=https://7d48.documents.azure.com:443/;",
    "BlogConnection_ProviderName": "Cosmos1",
    "BlogConnection2_Cosmos": "AccountEndpoint=https://7d48.documents.azure.com:443/;"
  }
}

Basic usage:

IConfiguration configuration;
var connStrManager = new ConnectionStringManager(configuration);
var conn = connStrManager["defaultConnection"];
if (conn != null) {
    if (conn.Provider == DbProviders.PostgreSQL) {
        ...
    } else if (conn.Provider == DbProviders.MySQL) {
        ...
    } else if (conn.Provider == DbProviders.SQLServer) {
        ...
    } else if (conn.Provider == DbProviders.Custom && conn.Custom == "Cosmos1") {
        ...
    }
}

Multi connectionNames:

var conn = connStrManager["BlogConnection", "BlogConnection2"];
if (conn != null) {
    if (conn.Provider == DbProviders.Custom && conn.Custom == "Cosmos1") {
        ...
    } else if (conn.Provider == DbProviders.Custom && conn.Custom == "Cosmos") {
        ...
    }
}
