Translate ninject ISecureDataFormat binding to Autofac

The migration from Ninject to Autofac seems to be correct, but the binding for the ISecureDataFormat<AuthenticationTicket> interface may not be working as expected, leading to an activation error in some dependencies. Based on the debugging messages, the BearerTokenCookieStore class is failing to resolve this dependency.

In the Ninject version, ISecureDataFormat<AuthenticationTicket> is bound to a method that retrieves the IOwinContext instance and uses it to resolve the ISecureDataFormat<AuthenticationTicket> named “SecureDataFormat.” However, in the Autofac version, the ISecureDataFormat<AuthenticationTicket> instance is directly resolved using the IOwinContext instance, but no name is provided.

It’s possible that the ISecureDataFormat<AuthenticationTicket> named "SecureDataFormat" is not being registered correctly in the Autofac container. To fix this, you can try registering the named instance explicitly using the Named extension method:

builder.Register(context =>
context.Resolve<IOwinContext>()
    .Get<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat"))
    .Named<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat");

builder.Register(context =>
    context.ResolveNamed<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat"))
    .As<ISecureDataFormat<AuthenticationTicket>>();

Then, in the BearerTokenCookieStore constructor, you can resolve the named instance like this:

public BearerTokenCookieStore(
    IOwinContext owinContext,
    [Named("SecureDataFormat")] ISecureDataFormat<AuthenticationTicket> secureDataFormat,
    IAppSettingsReader appSettingsReader,
    ICookieService cookieService)
{ }

This should ensure that the BearerTokenCookieStore class correctly resolves the ISecureDataFormat<AuthenticationTicket> named "SecureDataFormat" and that it is used by other dependencies that require it.
