## Overview

This is a small ASP.NET Web Forms example demonstrating employee validation with FluentValidation. A user submits the employee form; the click handler builds an Employee, invokes EmployeeValidator, then displays validation messages or a success message. The validator defines age, name, and email rules. Source excerpts show this flow, but the README does not document additional capabilities.

Main entry points: [`src/fluentValidation-test/default.aspx.cs`](https://github.com/bariskisir/fluent-validation-usage/blob/master/src/fluentValidation-test/default.aspx.cs) (Submit handler), [`src/fluentValidation-test/EmployeeValidator.cs`](https://github.com/bariskisir/fluent-validation-usage/blob/master/src/fluentValidation-test/EmployeeValidator.cs) (Employee validator), [`src/fluentValidation-test/default.aspx`](https://github.com/bariskisir/fluent-validation-usage/blob/master/src/fluentValidation-test/default.aspx) (Employee form), [`src/fluentValidation-test/Employee.cs`](https://github.com/bariskisir/fluent-validation-usage/blob/master/src/fluentValidation-test/Employee.cs) (Employee)
