Answer 1

yes, i had the same message (on Calculate Linux with Monodevelop 5.0.1).
you should help it to locate the assembly.
Either place the assembly into GAC with "gacutil -i" or make symlink for bin folder with

ln -s . ./bin

in the directory of xsp4 binary (it is under ./bin/Debug if you just built it).

to understand it deeper you can instead of using fuslogvw do this:
1) Run with the environment variables MONO_LOG_LEVEL=info and MONO_LOG_MASK=asm set, e.g.

MONO_LOG_LEVEL=info MONO_LOG_MASK=asm mono yourapp.exe

The assembly probing and related logic will be printed to stdout.
2) See the mono(1) man page for more information.
