Get AuthenticationProperties in ASP.NET 5

Question

In ASP.NET 5 MVC 6 RC1 how do I retrieve AuthenticationProperties from within a controller or from a filter? HttpContext.Authentication does\'t seem to

Answer 1

In ASP.NET 5, retrieving the authentication properties is a bit cumbersome as it must be done by instantiating an AuthenticateContext:

var context = new AuthenticateContext("[your authentication scheme]");
await HttpContext.Authentication.AuthenticateAsync(context);

if (context.Principal == null || context.Properties == null) {
    throw new InvalidOperationException("The request is not authenticated.");
}

var properties = new AuthenticationProperties(context.Properties);
