This section serves as a bit of a FAQ for common issues and their resolutions.
Unable to find "asio.hpp"
You need to tell CMake where the ASIO headers are located. Please review the cmake instructions.
Unable to load DNP3CLRAdapter or one of its dependencies
.NET does not provide useful error messages when an assembly can't find a native dependency. The .NET bindings depend on the Visual C++ Runtime library for the version of visual studio you used to build them.
These packages can be found from Microsoft by searching for "visual studio c++ runtime" in your favorite search engine.
You might also see this error because CLRAdapter can't find openssl (libeay32.dll / libssl32.dll) if your bindings didn't have these linked statically. The solution is to make sure openssl is installed in the correct system location.
Master or Outstation doesn't detect an ethernet cable being unplugged
There is no way through the standard socket API to detect this, other than trying to write data to the socket. This means that if master or outstation sessions are quiescent (meaning that they don't write data periodically), you should be using the link-layer keep-alive feature to ensure that dead/hung connections are appropriately detected.
