A few months ago I asked a question on stack overflow about how to implement Localization in MVC 6 , unfortunately at that time MVC 6 was still in Beta 7 and the Localizaton services were not complete. Now that localization has been implemented by Microsoft guys , its worth doing a quick blog on how to implement Localization in MVC 6.

Step 1

The first step is to include the dependency for Localization Nuget package in project.json

  "Microsoft.AspNet.Localization": "1.0.0-*"

## Step 2

MVC 6 has taken IOC to the next level. To an extent that everything has to be included in the baked in Dependency injector.

The way to include Localization is to use the AddViewLocalization() and AddDataAnnotationsLocalization() functions

	   services.AddLocalization(options => 
					options.ResourcesPath = "Resources");
	   services.AddMvc()
			   .AddViewLocalization()
			   .AddDataAnnotationsLocalization();

Step 3

We must now configure the Localization services we have added.

var requestLocalizationOptions = new RequestLocalizationOptions
			{
				SupportedCultures = new List<CultureInfo>
				{
					new CultureInfo("hi-IN"),
					new CultureInfo("en-GB"),
				},
				SupportedUICultures = new List<CultureInfo>
				{
					new CultureInfo("hi-IN"),
					new CultureInfo("en-GB"),
				}
			};

app.UseRequestLocalization(requestLocalizationOptions,
				 new RequestCulture(new CultureInfo("hi-IN")));

The code above first sets 2 supported cultures. The UseRequestLocalization function sets the default culture and the options well.

Put it all to use

Now that we are done with all the configuration , we need to put it all to use.

 public class LoginViewModel
	{
		[Required(ErrorMessageResourceName ="EmailRequired",
			ErrorMessageResourceType 
				= typeof(MVC6_RESX.Resources.Resource))]
		public string Email { get; set; }
		...
	}

Note : This code is working on 25 Dec 2015 with MVC 6 RC1.
