This is an awesome write up -- I came across your blog while trying to solve this very problem for a different platform and thinking that the issue would affect Raspberry pi's as well and someone, somewhere, might have solved it.
I have a request! Is it possible for you to build an ARM64 version of your package? I'm trying to do dotnet coding on an Android tablet with an Ubuntu userland (oh yeah) and surprisingly everything works but gRPC! Before I found your blog, I tried using the ARM64 Android .so and copying it over the x64.so but unfortunately that didn't work. I'm hoping an ARM64 build would be an quick task for you and would solve my problem.
I compiled it myself using the scripts and steps in your github project and it worked perfectly! In fact, I compiled it on my Android tablet.
I think perhaps the Android version would have worked but I didn't realize that dotnet overwrites the native libraries in your bin/Debug directory from the .nuget package store on every dotnet run.
Excellent! That's exactly what I was going to suggest.
And regarding the overwriting issue - that could be related to a bug, which I've filed a github issue for, which has to do with the tooling's selection process for the native library: github.com/dotnet/sdk/issues/4195.
I might have to check out these vector robots as you're the author of the .net sdk and another Wayne who commented earlier, was trying to control said Vector robot from a Pi, presumably using your sdk :)
