also have this bug
I have same issue. libbulletc.dll isn't included to nuget packet. It makes it's usage impossible. While it's possible to compile dll manually, some people(like me) might find it difficult.
It seems like after version 1.0.7 content files are not being included 
I've switched to 1.0.0 (1.0.7 crashed), but problem is that it only contains x64 binaries. It would be nice to have both x64 and x86 binaries in nuget.
Can't remember, but I either commented throw Exception or just added try catch. Bad solution, but at least works
