问题
I am bootstrapping Aurelia from a Web-forms based legacy application. My authentication related information is maintained in the web-forms application in the Custom Base Page class.
How do I pass & maintain this authentication information to Aurelia's global scope? So that I can use it while building the menus using routes to show/hide certain menu items based on the user/role?

You could put logic your custom base page to add a <script> tag to the head of the document that makes all the information available to javascript applications:
<head>
...
<script>
window.appInfo = {
user: 'foo',
bar: 'baz'
};
</script>
</head>
<body aurelia-app="main">
...
Then in your aurelia app you can access this info as needed:
export class App {
constructor() {
let info = window.appInfo;
// do something with the app info...
}
...
}
You could even register the object in the container, enabling you to declare it as a dependency. This will make your code more portable and testable.
In main.js: aurelia.container.registerInstance('app-info', window.appInfo);
@inject('app-info')
export class App {
constructor(info) {
// do something with the app info...
}
...
}
