Localization Strategy

Supported Resource Models

• Static .resx files with auto-generated .Designer.cs
• Static resource classes with constant string fields

Message Resolution Flow

1. Explicit Resource Name
   If ErrorMessageResourceName property is provided:

   • Use ErrorMessageResourceType if set
   • Otherwise, fall back to the model’s [ValidationResource] attribute
   • Retrieve static property by name and format

2. Conventional Key (Property_Attribute)
   Construct key from property name and attribute type
   e.g. Email_Required → ValidationMessages.Email_Required

3. Inline Message or Fallback
   If ErrorMessage is set, format and return it
   Else, fallback to "Invalid value for {Property}"

Example

[Required(ErrorMessageResourceName = "CustomEmailRequired")]
public string Email { get; set; }

public static class ValidationMessages
{
    public const string CustomEmailRequired = "Please provide your email.";
}
