If you use membership in ASP.NET Web Pages, you might get the error To call this method, the "Membership.Provider" property must be an instance of "ExtendedMembershipProvider":

I happened to run across this while playing around with the new OAuth login capabilities in the beta version of Web Pages 2, but you might see it under other conditions as well.

Per one of our testers, this can indicate that the server has no AspNetSqlMembershipProvider configured. (A clue here is that everything works great when you test locally, but then throws an error when you deploy to your hosting provider.)

In my case, I fixed this by adding the following to the site's local Web.config file:

<appSettings>
  <add key="enableSimpleMembership" value="true" />
</appSettings>

This is a child of the <configuration> element and a peer of the <system.web> element.

Anyway, that worked for me. I'm curious if others have seen this error and if so, how they fixed it.

mike, may i ask you a question... do you know if webpages authentication, roles and profile simple membership system supports anonymous identification? brgds

@sebastian, I'm going to say no because I'm not seeing any support for anonymous authentication in the SimpleMemebership provider (http://msdn.microsoft.com/en-us/library/webmatrix.webdata.simplemembershipprovider(VS.99).aspx). However, I'll pass the question along.

thank you mike, yes it seems that anonymous identification is not supported by simplemembership. anonymous information must be managed with cookies as far I read.

brgds ,great blog.
