asp.net mvc custom profile provider - asp.net

Question

I want to have custom profile provider in my asp.net mvc 3 app. The problem is, that I don't want to use default DB that is generated by ASP.NET Membership/Role/Profile provider, mainly because authentication is already done with WebService and DBs already exist.
I want to user profile properties to populate them and use within different areas of the site.
I took a look at this example (How to assign Profile values?) but I am getting this error:
An attempt to attach an auto-named database for file
C:\Projects\FWManager\App_Data\aspnetdb.mdf failed. A database with
the same name exists, or specified file cannot be opened, or it is
located on UNC share.
Here is the web.config
<profile inherits="FWMembership.Membership.FWProfileProvider" defaultProvider="AspNetSqlProfileProvider" automaticSaveEnabled="false" enabled="true">
<providers>
<clear/>
<add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/" />
</providers>
</profile>
This is my custom class
public class FWProfileProvider : ProfileBase
{
[SettingsAllowAnonymous(false)]
public string FirstName
{
get { return base["FirstName"] as string; }
set { base["FirstName"] = value; }
}
[SettingsAllowAnonymous(false)]
public string LastName
{
get { return base["LastName"] as string; }
set { base["LastName"] = value; }
}
[SettingsAllowAnonymous(false)]
public int? UserID
{
get { return base["UserID"] as int?; }
set { base["UserID"] = value; }
}
[SettingsAllowAnonymous(false)]
public string UserCompany
{
get { return base["UserCompany"] as string; }
set { base["UserCompany"] = value; }
}
[SettingsAllowAnonymous(false)]
public string Email
{
get { return base["Email"] as string; }
set { base["Email"] = value; }
}
public StringCollection Entitlements
{
get { return base["Entitlements"] as StringCollection; }
set { base["Entitlements"] = value; }
}
public string username;
public FWProfileProvider()
{
}
public FWProfileProvider(string username)
{
this.username = username;
}
static public FWProfileProvider CurrentUser
{
get
{
return (FWProfileProvider)
(ProfileBase.Create("Joe"));
}
}
}
The key is to avoid using asp.net default membership tables.
Any ideas?
EDIT:
Forgot to add - this web application, but profile provider is placed in the class library project within same soulution:

I think you have to write your own MemberShip Provider as well. Your web.config refers to the default asp.net membership provider. How to write a Membership provider you can find here custom membership provider
The default membership provider uses a connection string into a locally installed SQL Express database and that causes your error.
Your web.config would look like this:
<membership defaultProvider="MyCustomMembershipProvider">
<providers>
<clear />
<add name="MyCustomMembershipProvider"
type="FWMembership.Membership.MyCustomMembershipProvider"
enablePasswordRetrieval="true"
enablePasswordReset="true"
requiresQuestionAndAnswer="false"
requiresUniqueEmail="true"
passwordFormat="Clear"/>
</providers>
</membership>
<profile defaultProvider="MyProfileProvider" enabled="true">
<providers>
<clear/>
<add name="MyProfileProvider" type="FWMembership.Membership.FWProfileProvider" connectionStringName="ApplicationServices" applicationName="/" />
</providers>
</profile>
Hope this helps.
