Custom FluentValidation translations for most built-in validators. BaseValidationApiController implemented with common error responses. Return ErrorModel with ModelState fields errors and with array of custom errors.

Packed as two NuGet packages. Core project with translations and AspNetCore project:

• LSolutions.Api.FluentValidation
• LSolutions.Api.FluentValidation.AspNetCore

Usage

1. Add code below in your Startup.cs

    public void ConfigureServices(IServiceCollection services)
	{
		services
			.AddControllers(configure =>
			{
				configure.Filters.Add(typeof(ValidateModelActionFilter));
			})

			// Fluent validation
			.AddFluentValidation(fv =>
			{
				// Register fluent validation as only validation library that executes
				fv.DisableDataAnnotationsValidation = true;

				fv.ImplicitlyValidateChildProperties = true;

				fv.RegisterValidatorsFromAssemblyContaining<IValidatorResult>();
				fv.RegisterValidatorsFromAssemblyContaining<Startup>();
			});
			
		
		// Fluent validation localization
		// https://fluentvalidation.net/localization
		ValidatorOptions.Global.LanguageManager = new ApiEnglishLanguageManager();
		ValidatorOptions.Global.LanguageManager.Culture = new CultureInfo("en");
}

2. Extend ApiEnglishLanguageManager with translations for your custom validators.
