In regards to my a little to late discovery that static libraries (obviously) can't have instance members, http://stackoverflow.com/questions/708155/how-to-reference-property-on-library/708263#708263, is there a way to create a shared library that contains both instance and static members?
On way that probably works is to create a class file, save it to some shared directory and reference it from multiple projects. Is there a better way?
