Logging
Logging

Logging
NLog.RabbitMQ

Logging
NLog.Targets.ElasticSearch
There are no nuget packages available, but I created one myself.
Mailing
Mandrill
There are no nuget packages availabe, but you can use SMTP or a small webjob without .NET Core.
Azure Storage
WindowsAzure.Storage
There has a nuget package available v7.2.1.
BUT...
https://github.com/Azure/azure-storage-net/blob/master/README.md#odata
This version depends on three libraries (collectively referred to as ODataLib), which are resolved through the ODataLib (version 5.6.4) packages available through NuGet and not the WCF Data Services installer which currently contains 5.0.0 versions.
The ODataLib libraries can be downloaded directly or referenced by your code project through NuGet.
The specific ODataLib packages are:
[*]Microsoft.Data.OData
[*]Microsoft.Data.Edm
[*]System.Spatial
Note: The ODataLib packages currently do not support "netstandard1.6" or "netcoreapp1.0" frameworks in projects depending on the current relase of Dotnet CoreCLR. Thus, you may encounter failures while trying to restore the ODataLib dependencies for one of the targeted frameworks mentioned above. Until the support is added, if you run into this, you can use the imports statement within the framework node of your project.json file to specify to NuGet that it can restore the packages targeting the framework within the "imports" statement as shown below:
"imports": [
"dnxcore50",
"portable-net451+win8"
]
Azure ServiceBus
WindowsAzure.ServiceBus
There are no nuget packages availabe.
Identity
Microsoft.AspNet.Identity.Core
There has a nuget package available.
Identity
Microsoft.AspNet.Identity.Owin
There has a nuget package available.
Configuration (It's a big improvement for unit testing.)
Configuration
appsettings.json
{
"Logging": {
"IncludeScopes": false,
"LogLevel": {
"Default": "Debug",
"System": "Information",
"Microsoft": "Information"
}
}
}
C#
public class LoggingConfig
{
public bool IncludeScopes { get; set; }
public LogLevelConfig LogLevel { get; set; }
}
public LogLevelConfig
{
public string Default { get; set; }
public string System { get; set; }
public string Microsoft { get; set; }
}
public class Startup
{
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
.AddEnvironmentVariables();
Configuration = builder.Build();
}
public IConfigurationRoot Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.Configure<LoggingConfig>(Configuration.GetSection("Logging"));
services.AddMvc();
}
}
public class HomeController : Controller
{
public HomeController(IOptions<LoggingConfig> loggingConfig)
{
}
}
Configuration (Switch build configuration was a hell but not an
ymore.)
Configuration per environment
You can copy appsettings.json per environment, e.g. appsettings.development.json, appsettings.staging.json, appsettings.production.json
The default code template already support this see the below code:
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
Based on IHostingEnvironment you can do all the magic
public class HomeController : Controller
{
public HomeController(IHostingEnvironment env)
{
var environmentName = env.EnvironmentName;
var isDevelopment = env.IsDevelopment();
var isStaging = env.IsStaging();
var isProduction = env.IsProduction();
}
}
How to switch the environment?
In the end the environment variables will be saved into launchSettings.json
Based on the below command you can switch the environment easily
dotnet run --environment "Staging"
How are we going to do with the automatically deployment?
[*]Azure web apps
In the project.json please include (appsettings.development.json, appsettings.staging.json, appsettings.production.json)
{
"publishOptions": {
"include": [
"wwwroot",
"**/*.cshtml",
"appsettings.json",
"appsettings.Development.json",
"appsettings.Staging.json",
"appsettings.Production.json",
"web.config"
]
}
You can add a slot setting via Azure portal see the below screenshot
[*]Azure cloud services
One possible way would be to run prepublish or postpublic scripts/commands
IoC
Dependency injection
public class Startup
{
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddTransient<ITransientService, TransientService>();
services.AddScoped<IScopedService, ScopedService>();
services.AddSingleton<ISingletonService, SingletonService>();
services.AddMvc();
}
}
TransientTransient lifetime services are created each time they are requested. This lifetime works best for lightweight, stateless services.
ScopedScoped lifetime services are created once per request.
SingletonSingleton lifetime services are created the first time they are requested (or whenConfigureServices is run if you specify an instance there) and then every subsequent request will use the same instance. If your application requires singleton behavior, allowing the services container to manage the service’s lifetime is recommended instead of implementing the singleton design pattern and managing your object’s lifetime in the class yourself.
How to replace the default services container?
public class Startup
{
// This method gets called by the runtime. Use this method to add services to the container.
public IServiceProvider ConfigureServices(IServiceCollection services)
{
services.AddMvc();
var containerBuilder = new ContainerBuilder();
containerBuilder.RegisterType<TransientService>().As<ITransientService>().InstancePerDependency();
containerBuilder.RegisterType<ScopedService>().As<IScopedService>().InstancePerRequest();
containerBuilder.RegisterType<SingletonService>().As<ISingletonService>().SingleInstance();
containerBuilder.Populate(services);
var container = containerBuilder.Build();
return new AutofacServiceProvider(container);
}
}

Globalization and localization
