I removed guid.hpp from libLAS due to the fact that a better and more complete version is available in boost nowadays. Take a look at the changesets to c_api.cpp for an idea how to use the boost guid stuff instead of libLAS' version.

FileCreate and FileOpen were modified quite a while ago. The C# versions need to be updated to match.

I did not port any of the changes I made for 1.8.0 to the C# bindings. I had no idea anyone was actually using them :)

Hope this helps,
