Explain that.

You cannot do unmanaged things in a managed (CLI) application.

You are probably referencing into an Any CPU or x64 project, which is
not guaranteed to work, and/or may require additional parameters.

I'm not sure how you link the Boost DLL with the target application.

As I and others have stated, you can do this with your C++/CLI
project, i.e. using Boost "inside", so to speak, but you need to be
aware of the CLI-isms bridging into the .NET managed memory space.

Show some projects on Github exactly what you're doing.
