It shouldn't have a problem with the 3.5 framework. I haven't had an
occasion to try it with xaml, but I can easily imagine it
failing...it's going to be doing reflection all over the place, and
obfuscar scrambles the metadata needed to match the xaml to the
underlying code. Without also obfuscating the references in the xaml
to match the code, or without skipping obfuscation of the parts of the
code referenced by the xaml, it's pretty unlikely to work.
