With DSC resources you have two options (depending on what version of Chef you are running and what version of the Windows Management Framework or WMF).
Chef 11.16.0 introduced dsc_script which works with WMF 4 or greater. dsc_script can either embed a bit of DSC configuration syntax or point to an existing dsc configuration script.
dsc_resource is newer and relies on WMF 5 (February preview). That is a more natural use of DSC from Chef, but relies on newer features that aren’t as far downlevel yet (2012 or 2012 R2).
Take a look at the github repo from my ChefConf demo: http://bit.ly/chefconf_dsc or my talk: http://bit.ly/chefconf2015_dsc_video
There are examples of dsc_script, dsc_resource, an equivalent recipe with just powershell_script, and the DSC configuration equivalent.
As far as custom resources themselves, you are responsible for getting the resources on the node. You could use remote_file, chocolatey, PowerShellGet, PSGet or any other method you can think of to stage the resources.
With some of the changes in WMF5, we may be able to also use a pull server to distribute resources, but I have to test that yet.

Ohai Chef Community!
I’m planning on designing a cookbook that uses some custom DSC resources. Matt Wrock has an excellent example (https://github.com/mwrock/dsc_nugetserver) using dsc_* Chef resources, but the actual DSC resources all come from the DSC Resource Kit.
I’m looking for a few things in particular when it comes to using custom DSC resources:
Do I need both Chef Server (host cookbooks) + DSC Pull Server (host custom DSC resources)?
Is the use of a *.ps1 configuration file required when using DSC resources in cookbooks?
Is it fair to draw comparisons of developing a DSC resource to developing an LWRP?
If so, how are dependent DSC resources pulled in to a recipe for use? LWRPs have the advantage of either being part of the cookbook itself or dependent cookbooks.
Thanks for any help/suggestions/support!
