Why can't it find my BasicAuthenticationModule?

Question

I'm trying to create my own implementation of a basic-authentication.

I have BasicAuthenticationModule.cs stored in my solution\\Modules and its namespace is:

namespace Web_API.Modules
{
public class BasicAuthenticationModule2 : IHttpModule

Ive added it to my web.config as such:

<system.webServer>
    <modules>
      <add name="BasicAuthenticationModule" type="Web_API.Modules.BasicAuthenticationModule, BasicAuthenticationModule"/>

Running this gets me: HTTP Error 500.19 - Internal Server Error - Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'BasicAuthenticationModule'

Does anyone have a clue?

Answer 1

The reason is because there already is a built-in module called BasicAuthorizationModule that comes inside .NET.

You would need to either:

• use a different Name (eg BasicAuthModule )
• remove the existing BasicAuthorizationModeule module entry
