I check the arrays.hpp.rule file and the contents is just this line: "# generated from CMake"
thats it, what generates that file and how would i go about troubleshotting it, im not sure what if thats expected or normal.

Hi @InfoShellTex,

sorry for the late reply, but was busy at work and spare time recently.

I don't have a working windows ROS2 dotnet setup myself yet. I started setting it up, but all those manual install steps did take longer than I thought last time I started this, since then I haven't continued.
So I'm sorry I can't really dig into this right now, but I will look at this once I have that setup again.

btw. Wat was the reason to close your other Issue (#115)? Did you resolve it? Maybe you could write a short note what to did to resolve it for others that stumble upon this later on.

[InfoShellTex]

I did not resolve it. I closed it because I am now building off of the foxy version, since i can successfully install it, where the #115 was using humble (from binaries), to me, didnt feel like a complete install compared to foxy.
And i didn't want to have many things going on at once. But Im fine with it being reopened as that issue still does exist.

And thanks, no worries! any help is better than none at this point.
