Hey guys, we just shipped the Validation Bundle.
The guidance in this bundle is designed to help you streamline the end-user experience of your web applications by utilizing ASP.NET AJAX to invoke server-side validation. Additionally you will find guidance on how to improve maintainability of your applications by reusing domain object validations across multiple screens, applications and tiers. You'll also find a set of guidelines on how to perform security validation in order to protect your sites from SQL Injection, Cross-Site scripting, etc. Like the Contextual Autocomplete Bundle, this guidance is applicable for both WCSF and standard ASP.NET non-WCSF based solutions.
Go check it out here and let us know what you think! Also check out what others are saying.
