Is there any way to prefix the new .NET 4.5 DefaultMembershipProvider table names in the database? They used to be named aspnet_Users, aspnet_Roles etc. and they are now named just Users, Roles, etc. which is conflicting with my application schema that has a table User.
Is my only option to use a separate database for membership if I want to use the new universal providers and avoid this naming issue?
Unfortunately there is no way to customize the table names for the Universal Providers currently, I'll make sure we consider adding support for this in the future.
It may be possible to have DefaultMembershipProvider use tables under a different schema by having it connect to SQL with a login which maps to a non-default schema (e.g. "membership") in the target database. In SSMS, look at the Login Properties, User Mapping, Default Schema. That way, the application's [dbo].[Users] would not conflict with [membership].[Users].
