How to get to strongly typed Member object in GenerateUserIdentityAsync

[dhymik]

How can I access the Umbraco Member object in a strongly typed way in GenerateUserIdentityAsync? And how can I use the strongly typed Member model to post changes?

I figured out how to access the properties of my Members type through the 'UmbracoApplicatonMember.MemberProperties` property.

However, I have failed so far in finding a way to cast this to the Member model. Can this be done? Can I access the Umbraco MembershipHelper, or is there another way?

And if this is possible, can I then cast the Members object back to 'UmbracoApplicatonMember` to persist changes?

I am grateful for some guidance on this.
