Custom Membership provider not loading from web.config

I have a MVC 5 application which I created a custom membership provider for.

I have configured it in the web.config, but it seems that the app is not reading it from the web.config file.

This is what my config file looks like.

<membership defaultProvider="SQLMembershipProviders" userIsOnlineTimeWindow="15"><providers><clear/><add name="SQLMembershipProvider"
        type="MyApp.Membership.SQLMembershipProvider"
        connectionStringName="primaryConnectionString"
        enablePasswordRetrieval="false"
        enablePasswordReset="true"
        requiresQuestionAndAnswer="false"
        writeExceptionsToEventLog="true" /></providers></membership>

Any insight will be greatly appreciated.
