This project does link the FSharp runtime into the DLL which is likely the source of the FS2009 warnings. Unfortunately though I can’t find any information on what this warning is, how to mitigate it, etc … Looked in a number of places but coming up empty. Want to try and understand this warning so I can move forward with fixing this correctly vs suppressing and moving on.

A bit more detail. I noticed when looking at the binlog file that this warning is only happening when building the net6.0 target framework. The net472 target framework builds without any issues

@jaredpar , just to follow up from our earlier chat. This is absolutely supported on the coreclr, if it weren’t then generative type providers would fail to work. We currently have a bug that adds an unnecssary reference, I haven’t tracked down where and why yet, but I am working on it.
