Problem with Forms Authentication Provider

[Magnus021]

Hi, I have a problem with adding users to my database that I have created using the aspnet_regsql. The problem is that I can't seem to make it add users into the database using the WAT.

I can connect to the database using sql connection in c sharp and I can see the database from the database explorer.

maybe something is wrong with my code?

<configuration>
    <system.web>
        <authentication mode="Forms" />
      <membership>
        <providers>
          <add connectionStringName="MyMembershipConnString" applicationName="MyMembership"
            enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true"
            requiresUniqueEmail="true" passwordFormat="Hashed" name="MyMembershipProvider"
            type="System.Web.Security.SqlMembershipProvider" />
        </providers>
      </membership>
      
        <compilation debug="true" targetFramework="4.0" />
    </system.web>
  
  <connectionStrings>
    <add name="MyMembershipConnString"
         connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=aspnetdb;Integrated Security=True"/>
  </connectionStrings>
</configuration> 

thx for helping!
