C# Membership.ValidateUser(Username, Password) throwing an exception
<p>I am trying to validate a user using the Membership.ValidateUser() method. I pass the correct username and password, and the authentical always failed. The Else section of the code is executed. I add a breakpoint, and I notice the following: 'Response.Headers' threw an exception of type 'System.PlatformNotSupportedException - This operation requires IIS integrated pipeline'. I check the application pool, and it is set to use <strong>Integrated pipeline.</strong></p>

<p>The create Membership.CreateUser() works fine.  I am only having issue retrieving users. Below is my web.config file.</p>

<p>I look at the definition, and this is all that is showing 
public static bool ValidateUser(string username, string password) (under the page name [Membership from metadata] . </p>
