The xVal was designed to be a validation framework for ASP.NET MVC applications. It makes it easy to link up your choice of server-side validation mechanism with your choice of client-side validation library, neatly fitting both into ASP.NET MVC architecture and conventions.

XVal Crack+ Activation Key
The core of xVal Cracked Accounts is in implementing a standard for validating ASP.NET MVC actions. It allows developers to test their validation logic easily in a development environment without needing to add custom validation attributes.
It provides an easy integration with HTML5’s validation features, as well as with existing validators.
xVal uses Code Contracts to provide easy to use, highly efficient, automated error checking. It shows errors in running applications, and does so without the need to instantiate controllers, change routing, or perform any other ASP.NET MVC setup.
Start using xVal by downloading the latest release of the NuGet package.

Important! If you develop apps with xVal, you’ll need to install the latest version of the Microsoft.CodeContracts NuGet package and add it to your solution. If you’re using Visual Studio 2012, you’ll find it in the.NET 4.5 features pane.
Other Easier Ways of Validation
If you want to use regular server-side validation in MVC, xVal has the same features. However, you should be using xVal because it has superior performance, and when you enable Code Contracts, it has the same results without the need of instantiating controllers, changing routing, or performing any other ASP.NET MVC setup.
If you want to use jQuery validation, it has the same features as xVal.

See MVC 4 Client-Side Validation using jQuery for more information about jQuery validation and related topics.
It’s worth reading the official documentation and the official mailing list (including the list archive).
You can also take a look at the source of xVal that I have modified a bit and using it in some commercial projects. Just contact me for licensing issues.
I have the same problem as you: I want to develop JQuery Validation which reads from my database (not Xml) and provides a set of rules.
So far I have yet to find out how to create rules for my database, or how to plug such rules to JQuery.

The software engineering challenge of building custom validation controls is a hard one, to be honest, and it often shows when something goes wrong. Trying to keep up with the countless features created every day is hard enough when building a new solution, but to do it for another developer with a different choice of client-side validation library is even more complicated. Choosing a standard framework and relying on a generic library only makes things more complicated, as all of these frameworks have their own set of pros and cons. At best this means they all end up having to be learned, and at worst they end up not being used at all.
The xVal framework attempts to reduce this problem down by providing a uniform way to tie your custom server-side validation into your choice of client-side validation libraries with a set of simple class interfaces that map very closely to the server-side object you are modeling. That way, using an MVC framework like ASP.NET MVC is only half the battle. With this framework, you can add custom validation into your application without a lot of hassle and still have the ability to mix and match validation libraries easily (through a use of xVal classes).
When the MVC architecture for ASP.NET was being built, James Tuckey realized that something was needed to allow for a consistent way to integrate server-side and client-side validation. So, he extended the ASP.NET MVC Model Validation Framework with this new functionality. The xVal framework is the updated version, which is a standardized way for ASP.NET MVC programmers to integrate server-side validation and then use their choice of client-side validation libraries.
xVal How It Works:
xVal’s main classes all have a ValidationContext as a parameter, which simply gives you the current object being validated. There’s a helper class (the ValidateObject helper) that you can use to create
What’s New in the?
xVal is a simple validation framework that works with the ASP.NET MVC Framework and the jQuery libraries.
xVal is made of two parts: xVal.Server and xVal.Client.
xVal.Server adds a new filter to the ASP.NET MVC ActionResult for using our model validation layers (models). It also adds a new class library, xVal.Server.Client.
xVal.Server contains a number of functions for working with the client-side validation methods.
Creates a new ValidationSummary helper that formats the validation summary tags for the client-side code.
Retrieve the ValidationSummary tag from the HTML page.
Retrieve the client-side validation parameters for the specified field in the current model.
Retrieve the client-side error messages for the specified field in the current model.
Retrieve the client-side validation settings for the specified field in the current model.
Retrieve the client-side validation rules for the specified field in the current model.
Retrieve the validation summary control for the specified field in the current model.
Retrieve the validation summary messages for the specified field in the current model.
Retrieve the HTML summary of the specified field in the current model.
Creates a new jQuery form validation plugin.
