  1. Install the NuGet package

  2. In the ConfigureServices method of Startup.cs, include a call to AddFluentValidationFilter instead of AddFluentValidation.

public void ConfigureServices(IServiceCollection services)

  1. In order for ASP.NET to discover your validators, they must be registered with the services collection. You must do this by calling the AddTransient method for each of your validators. Adding all validators in a specified assembly is not supported.

    services.AddTransient<IValidator<Person>, PersonValidator>();
    // (repeat for every validator)

How to use

For any given endpoint, add the query-string ?validation=1 to the endpoint URL in order to view the validator details, if applicable.

Example output for JSON:

  "rules": {
    "foreName": {
      "required": true,
      "length": {
        "min": 2,
        "max": 10
    "address.line1": {
      "required": true
  "messages": {
    "foreName": {
      "required": "'Forename' must not be empty.",
      "length": "'Forename' must be between 2 and 10 characters."
    "address.line1": {
      "required": "'Line1' must not be empty."

AJAX validation

For unsupported validators or validators with custom server-side logic, the rule will be presented as "remote" - the field can be validated using an AJAX call to the back-end.

You can validate any particular field by adding the query string validate=fieldName and if the field is not valid, a problem details will be returned including errors only relevant to the specified field.
