BadImageFormatException

[vilinski]

Sadly I have no Idea how to reproduce it

comes periodically after significant error free execution time like a couple of minutes

Tried compiling this project yourself on .Net 5?

This error occurs if the Hopac library is compiled with dotnet 5, if compiled with version 2 or 3 everything works.

This test also fails

I'm not writing F# during my day work any longer, but I could look into merging PR:s if I receive them. Thanks for debugging @RahimovIR

[RahimovIR]

@haf I created #213 but I want to note that changing the dotnet version does not solve the @vilinski problem, since it has an error on version 0.5.0, PR solves the problem for 0.5.1
