• C# 9 syntax applied to shorted code.

1.0.3

• Fixed bug in Multilang - English Error Describer (default IdentityErrorDescriber included in Microsoft.Extensions.Identity.Core) is used for 'en' or no language provided.

Multilanguage

Error messages can be generated based on accept-language HTTP header. For this, install PiotrTrojan.AspNetCore.IdentityErrorLocalization.Multilang package, register proper factory:

serviceCollection.RegisterIdentityErrorDescriberFactory();

and proper error describer

serviceCollection
  .AddIdentity<IdentityUser<Guid>, IdentityRole<Guid>>() // Returns IdentityBuilder, Generics just as an example.
  .AddMultilangIdentityErrorDescriber(); // Multilanguage support added.

Specific language

To add localization to your Identity use Add{X}IdentityErrorDescriber() method to your IdentityBuilder chain, where {X} is your desired language. Languages currently available:

• German (de-DE)
• Spanish (es-ES)
• Persian (fa-IR)
• French (fr-FR)
• Polish (pl-PL)
• Portuguese (pt-PT)
• Swedish (sv-SE)
• Russian (ru-RU)
• Turkish (tr-TR)
• Ukrainian (uk-UA)

Example:

serviceCollection
  .AddIdentity<IdentityUser<Guid>, IdentityRole<Guid>>() // Returns IdentityBuilder
  .AddPolishIdentityErrorDescriber(); // Polish errors translations added

Every available language is in separate package, PiotrTrojan.AspNetCore.IdentityErrorLocalization.{Culture}, e.g. PiotrTrojan.AspNetCore.IdentityErrorLocalization.de-DE

Feel free to suggest me improvements or to help me with new languages.

This is my first open source project ;)
