ASP.Net Membership Change Password method does not show up

Question

I have implemented a Custom Membership provider. A sample of my code is shown below

public class CustomMembershipProvider : MembershipProvider
{
   public override bool ChangePassword(string username, string oldPassword, string newPassword)
   {
      //logic for changing password
   }

   public override bool ValidateUser(string username, string password)
   {
      //logic for validating user credentials
   }
}

I then registered the above Custom Membership in the web.config file by using

<membership defaultProvider="CustomMembershipProvider">
 <providers>
  <clear/>
   <add name ="CustomMembershipProvider" type="MyApplication.CustomMembershipProvider"/>
 </providers>
</membership>

Now, when I want to authenticate a user, I can call

System.Web.Security.Membership.ValidateUser(username, password);

This works. However, when I want to call the method to change the password, I try calling:

System.Web.Security.Membership.ChangePassword(username, oldPassword, newPassword);

It gives me intellisense and compilation errors saying that System.Web.Security.Membership does not contain the definition for ChangePassword.

How do I link my ChangePassword method to be callable from System.Web.Security.Membership or am I approaching this problem in the wrong way?

Make sure your Membership provider is well defined:

<membership defaultProvider="CustomMembershipProvider">
  <providers>
    <clear />
    <add connectionStringName="ConnString" enablePasswordReset="true" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" name="CustomMembershipProvider" type="MyMembershipProvider" />
  </providers>
</membership>

I take it that MyApplication.MyMembershipProvider is your custom Membership class. I would rename to something else to make the web.config easier to read later, so you know what is the class when you see it.

However, what I believe the answer to your problem is, you need to tap into the Provider class within Membership. Since your defined a Custom Provider, you will use this to execute some of your custom changes.

var didChange = System.Web.Security.Membership.Provider.ChangePassword("", "", "");

The error from Visual Studio is 'System.Web.Security.Membership' does not contain a definition for 'ChangePassword'

no luck. I tried your web.config change along with a rebuild of the entire solution but it still doesnt show up.
