AD FBA membership provider 2013

I would like to set up AD FBA, so I followed several articles. But all of them are saying that in web.config files, I must put :

<add name="ADMembers"
             type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
             connectionStringName="adconn"
             enableSearchMethods="true"
             attributeMapUsername="sAMAccountName" />

But "Version=2.0.0.0" is an old version, no ? And when I set up FBA againt AD LDS, I remembered that this was an error I had.

Here is the blog I followed.
