Extensions

some extensions for Stream and collectopns

Simple.DI

Pierian spring: https://github.com/reactiveui/splat and using like a Splat.Locator, but has litle different names

Using

	using Dimple.DI;
	static InitDi()
	{
		var db = new SomethingDataBase(...);
		var setup = Locator.Setup();
		setup
			.AddSingleton(db)
			.AddSingleton<IRepoSomething>(() => new RepoSomething(db))
			//or	.AddSingleton<IRepoSomething>(sp => new RepoSomething(sp.GetService<SomethingDataBase>()))
			.AddSingleton<IOthers>(...) ...
	}
...
	using Dimple.DI;
	private readonly IRepoSomething _repo;
	public AnyService()
	{
		_repo = Locator.Current.GetService<IRepoSomething>();
	}

Simple.Configuration

Easy way to use JSON and Envirement parameters, which used like a MS in "Hosting" flow

Using

    var builder = new ConfigurationBuilder()
        .SetBasePath(context.HostingEnvironment.ContentRootPath)
        .AddJsonFile("appsettings.json")
        .AddJsonFile($"appsettings.{env.EnvironmentName}.json", true);

    var configuration = builder.Build();

	Locator.Setup().AddConst<IConfiguration>(configuration);
...
    var configuration = Locator.Current.GetService<IConfiguration>();
	var myConfig = configuration.Json.GetValue("some section").ToObject<MyConfig>();

Simple.Ttl

Using

private IRepoConfig _repo = ...
private readonly TtlValue _configApp(TimeSpan.FromMinutes(5));

...

public IConfigApp GetAppConfig()
	=> _configApp.GetOrCreate(() => new ConfigApp(_repo.Get...(...)));

OR

public Task<IConfigApp> GetAppConfigAsync()
	=> _configApp.GetOrCreateAsync(() => Get...Async(...));
