Like Matthias said "Ive so many plans, so many..." So i had stuck the same at "I.." statement and.. but Cochise is not loading and showing a progress bar

With reflexil i am unable to declare variables and by changing static arrays' size get private offsets ruined.
Tried to decompile a project and push it to VS 2015.
Alas, building results in a 10 thousand errors, and my baby steps are not enough for that. Why so many, what is missing, while the dll itself is running and ok ?
So maybe it is easier to use ildasm and ilasm to write directly in IL and be free to declare some simple thing like arrays, variables, access file, try to use available methods and code to do at least something ?
Also found some modifying guides on the net, but those are the same reflexil level cheat-hack.
Should i lean to ildasm and try to beat this dumb stack virtual machine or beat the VS and get the dll compiled back ?
I got that feeling of why no mods available. It is plain hard to do.
