I have reCaptcha installation problems. I already saw some posts about that, even in StackOverflow but it didn't help me to get it working.

I followed this post, and this post but in this line:

@using Microsoft.Web.Helpers

I get the message:

The type or namespace name 'Helpers' does not exist in the namespace 'Microsoft.Web' (are you missing an assembly reference?)

I added all references mentioned, all assemblies in both web.config files (root and view folder), restarted VS2010, updated the MVC3 package, included WebMatrix packages but I couldn't get it working.

I guess it should be simple to install, but I don't know what I'm doing wrong.

Anyone could help me?

Here's a step by step guide:

  1. Create a new ASP.NET MVC 3 project using the default template
  2. Install the microsoft-web-helpers NuGet

  3. In the Index.cshtml view of HomeController create a form and bring the Microsoft.Web.Helpers namespace into scope:

    @using Microsoft.Web.Helpers

@using (Html.BeginForm())
{
    @ReCaptcha.GetHtml(publicKey: "__ put your public key here __")
    <button type="submit">OK</button>
}

  4. And to validate the Captcha in the controller:

    [HttpPost]
public ActionResult Index(MyViewModel model)
{
    if (!ReCaptcha.Validate(privateKey: "__ put your private key here __"))
    {
        return View(model);
    }
    return RedirectToAction("success");
}

  • Thank you @Darin Dimitrov, I just wonder why I couldn't use this namespace in my app, I tried to download this you told me and it tells me is already installed, so weird. Thank you a lot. – Rubia Gardini Nov 26 '11 at 13:37
