ASP.Net Members in web.config remove provider

Question

I'm trying to avoid the ASPNETDB.mdf file to be added to my project.

I have this in my config file:

<authentication mode="Forms">
  <forms loginUrl="login.aspx" defaultUrl="Default.aspx" protection="All">
    <credentials passwordFormat="Clear">
      <user name="admin" password="Qwe456"/>
      <user name="Murergruppe" password="2012m"/>
      <user name="Skift-a" password="2012a"/>
      <user name="Skift-b" password="2012b"/>
      <user name="Skift-c" password="2012c"/>
      <user name="Skift-d" password="2012d"/>
      <user name="Skift-e" password="2012e"/>
    </credentials>
  </forms>
</authentication>

Then i've turned of the creation of ASPNETDB.mdf in machine.config

then it says it can't find the file. then I add:

<membership>
  <providers>
    <clear />
    <add type="Personal.Providers.WebConfigMembershipProvider" name="WebConfigMembershipProvider"/> 
  </providers>
</membership>

But then it says the default provider must be specified. What to do when i don't have any other providers?

Answer 1

 <membership defaultProvider="WebConfigMembershipProvider" userIsOnlineTimeWindow="20">
   <providers>
.....

You may specify the default one.
