用户代码未处理System.Configuration.ConfigurationErrorsException，消息=无法加载文件或程序集'System.Web

Question

I have read the following article http://msdn.microsoft.com/en-us/library/ff650307.aspx , about how i can authenticate asp.net mvc users from multiple domains, so inside my asp.net mvc i did the following :-

I added the following to my web.config:-

<system.web>
    <membership>
      <providers>
        <add name="TestDomain1ADMembershipProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web,               Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="TestDomain1ConnectionString" connectionUsername="ad-domainA.intra\it360ad.user" connectionPassword="$$$$$" />

      </providers>
    </membership>

&

<connectionStrings>

<add name="TestDomain1ConnectionString" connectionString="LDAP://ad-domainA.intra/CN=Users,DC=ad-domainA,DC=intra" />

and i added the following Account.controller:-

[AllowAnonymous]
        public ActionResult Login(string returnUrl)
        {
            ViewBag.ReturnUrl = returnUrl;
            return View();
        }

        //
        // POST: /Account/Login

        [HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public ActionResult Login(LoginModel model, string returnUrl)
        {


            MembershipProvider domainProvider;

            domainProvider = Membership.Providers["TestDomain1ADMembershipProvider"];


            // Validate the user with the membership system.
            if (domainProvider.ValidateUser(model.UserName, model.Password))
            {

                if (Request.QueryString["ReturnUrl"] != null)
                {

                    FormsAuthentication.RedirectFromLoginPage(
                        model.UserName, false);
                }
                else
                {
                    // If there is no RequestUrl query string attribute, just set
                    // the authentication cookie. Provide navigation on the login page
                    // to pages that require authentication, or user can use browser
                    // to navigate to protected pages.
                    // Set second parameter to false so cookie is not persistent
                    // across sessions.
                    FormsAuthentication.SetAuthCookie(model.UserName, false);
                }
            }
            else
        {

            ModelState.AddModelError("", "The user name or password provided is incorrect.");
            return View(model);
        }

            return RedirectToLocal(returnUrl);

        }

but when i type my user name and password inside the login screen and click on enter , i got the following error:-

on the following line of code inside the Account controller:-

public ActionResult Login(LoginModel model, string returnUrl)
        {MembershipProvider domainProvider;
domainProvider = Membership.Providers["TestDomain1ADMembershipProvider"];

so what is causing this error?

Answer 1

For this declaration of System.Web

System.Web, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a

The version is also needed (4.0 right?)

Version=4.0.0.0
