The SlimDX sample situation is currently pretty disorganized: some of our samples are checked in to the Subversion repository, but others are just referenced from issues in our issue tracker. Not all the samples use our internal sample framework, either, and the framework itself has a few issues. But as SlimDX becomes more and more stable, and begins to really approach complete parity with the native APIs, we have an opportunity to revisit problems like this one and clean things up.
