You use Mono on Windows ?

Would you mind setting

(setq fsharp-ac-debug 20)

to prevent truncation in the debug-log?

i did as jurgenhoetzel suggested and uploaded the new debug log

Thanks, but the debug log doesn't seem to be complete. It should start with

.... (fsharp-ac/load-project):  project "PATH_TO_YOUR_FSPROJ" verbose

Maybe you forget to set the debug level before opening the F# file?

I didnt forget. I dont get that message you referenced. Also, i dont load projects. I load just a single fsx file. i will attach my emacs file as a txt. init - Copy.txt

Sorry, I may have missed this. We need to investigate the:
