Cant configure MVC 4 SqlMembershipProvider - asp.net

Question

I am setting up my MVC 4 website to use SqlMembershipProvider with data store as SQL Server Express 11.0.21xx
I have installed Universal Providers via NuGet
PM > Install-Package Microsoft.AspNet.Providers
When I run the app and go to localhost/Accounts/Register and submit the form, I get this error
To call this method, the "Membership.Provider" property must be an instance of "ExtendedMembershipProvider".
at this line
WebSecurity.CreateUserAndAccount(model.UserName, model.Password);
Accounts controller has attribute [InitializeSimpleMembership] set. But the tables are not created due to aforementioned error.
web.config section updated by NuGet
<profile defaultProvider="DefaultProfileProvider">
<providers>
<add name="DefaultProfileProvider"
type="System.Web.Providers.DefaultProfileProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
connectionStringName="DefaultConnection"
applicationName="/" />
</providers>
</profile>
<membership defaultProvider="DefaultMembershipProvider">
<providers>
<add name="DefaultMembershipProvider"
type="System.Web.Providers.DefaultMembershipProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
connectionStringName="DefaultConnection"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="false"
requiresUniqueEmail="false"
maxInvalidPasswordAttempts="5"
minRequiredPasswordLength="6"
minRequiredNonalphanumericCharacters="0"
passwordAttemptWindow="10"
applicationName="/" />
</providers>
</membership>
<roleManager enabled="true" defaultProvider="DefaultRoleProvider">
<providers>
<add name="DefaultRoleProvider"
type="System.Web.Providers.DefaultRoleProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
connectionStringName="DefaultConnection"
applicationName="/" />
</providers>
</roleManager>
<sessionState mode="InProc" customProvider="DefaultSessionProvider">
<providers>
<add name="DefaultSessionProvider"
type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
connectionStringName="DefaultConnection" />
</providers>
</sessionState>
ConnectionString
<add name="DefaultConnection" connectionString="server=servername\instance;Database=imdb;User Id=sa; Password=passbird;" providerName="System.Data.SqlClient" />
Where's the problem? Should I use universal providers at all? I dont believe I should run aspnet_regsql cos of the new Account controller.

All I had to do was change DefaultMembershipProvider to SimpleMembershipProvider in web.config. type attribute is important to get it right.
<membership defaultProvider="DefaultMembershipProvider">
<providers>
<add name="DefaultMembershipProvider"
type="WebMatrix.WebData.SimpleMembershipProvider, WebMatrix.WebData"
connectionStringName="DefaultConnection"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="false"
requiresUniqueEmail="false"
maxInvalidPasswordAttempts="5"
minRequiredPasswordLength="6"
minRequiredNonalphanumericCharacters="0"
passwordAttemptWindow="10"
applicationName="/" />
</providers>
</membership>
<roleManager enabled="true" defaultProvider="DefaultRoleProvider">
<providers>
<add name="DefaultRoleProvider"
type="WebMatrix.WebData.SimpleRoleProvider, WebMatrix.WebData"
connectionStringName="DefaultConnection"
applicationName="/" />
</providers>
</roleManager>
