Error Compiling C++/CLI Module.

Hi. I need to compile a Managed C++ module in a Node.JS application. I read online that I need to enable CLI with the /clr flag, and set the msvs-settings and msbuild_settings attributes, it's still not working for me. I receive this error message:

cl : Command line error D8016: '/clr' and '/EHs' command-line options are incompatible [C:\MyProject\native-modules\encryption-utilities\addon\ build\encrypt.vcxproj]
I've gotten the information from this page: https://github.com/nodejs/node-gyp/issues/568

Here is my binding.gyp below. I've added the three items that are mentioned in this Issue ((1) cflags_cc, (2) msvs_settings, and (3) msbuild_settings), but it's still not working for me.

Thank you.

Start with the pasted binding.gyp and the reported D8016 error, then inspect the generated encrypt.vcxproj and node-gyp's Windows build configuration. Reproduce the build with the shown C++/CLI settings and determine which compiler options are being emitted. Done means the addon compiles without the incompatible-option error.
