Hello,

I'm new with Chef(and ruby), please excuse me if I'm just being thick.

I'm using the windows_feature provider from the windows cookbook to

install roles on a Windows 2012 server.

On W2012 however, you cannot install .Net framework 3.5 without

providing some installation sources.

So far, I work around that by using remote_directory and by shelling

out to cmd, something like:

I'd like to skip the remote_directory copy when the feature has been

installed, however, so my question is:

Is there no way to simply check if some feature/package is installed?

The provider implements the method 'installed?'. Can I not call it

somehow from my recipes?

I'm not very familiar with the Windows stuff, but it seems like you should be able to get the desired behavior with either `not_if` (and `only_if`) or notifications. Those are documented at the top of this page:

Thanks alot!
