I will use this post to catalog public resources on the Windows Biometric Framework.
If you run across any that I miss please let me know, I should reliably catch the technical content ;)

Will this be available on Vista and XP?
No, XP has been out of support for some time; http://support.microsoft.com/lifecycle/?p1=3223 Also backports of OS features seldom happen without significant market demand.
Are there any managed code wrappers for the Biometric Service APIs (i.e. the WinBio* calls)? I was going to play with this a bit, but having to translate the API's will slow me down.Another link for you is http://msdn.microsoft.com/en-us/library/dd401509(VS.85).aspx which is the Biometric Service API reference (it's surprisingly hard to find as the MSDN search won't pick it up).I haven't found any sample code for the client stuff anywhere yet. Have you seen any?
No at this time there are no managed code wrappers for the WBF API.At this time there is no sample code for the client APIs that I can point you at, hopefully in the near future there will be.
A partial managed wrapper can be found here: http://bioapprovalworkflow.codeplex.com/.
I have updated the list of URLs with a new reference, a partial managed wrapper written by a friend.
Hi, I'm doing a study about the WBF security and I wonder what are the possiblities for a malicious software on this system? Does a program who knows the SID of the logged user can delete his recorded fingers?Thanks
It only provides support for fingerprints. Is there plan to support other biometerics e.g. Iris etc?
Kumar - you are correct at this time only one BSP is provided, the one for fingerprints. Also at this time it is not posible for a third-party to add aditional BSPs, the design was done in such a way that both scenarios can be acomplished, I can not speak to what schedules that may happen on though.If I were to build a verticaly integrated Iris (or other modality) solution I would try to do so in a way that was stylistically consistent with the WBF so that migration would be easier when it does happen.
Ryan, I have a question that has been giving me a headache for a while, it is still without an answer. I hope you can offer some hints.My objective is to simply capture the raw data from the scanner and keep the data in a location of my choice.WinBioCaptureSample (in theory) does what I need, if I pass a specific param at the input."__out PWINBIO_BIR *Sample" should contain the raw sample.Unfortunately, the returned result is E_NOTIMPL. At first I thought this feature is not yet implemented; but after examining the docs again, I realized that it means "reader does not support it".I tried this with a lot of different readers, all of them were various flavours of Upek Touchchip (built into laptops, standalone; swipe sensors and touch sensors) - the behaviour is the same.Can you confirm that this feature is really working? And if yes, can you suggest a biometric reader I can try it with?Looking forward to your feedback,Alex
Are there any sample codes of WBF to work with?
Depends on what your looking for, each of hte interfaces have sample invocations in MSDN. A consultant wrote a sample applicaiton using it as part of a workflow approval: (http://www.jwsecure.com/files/Samples2009/Implementing_a_Biometric_Approval_Workflow.pdf) The driver development kit comes wth sample drivers also.What are you looking for?
