In recent projects, project source code confidentiality issues are involved, because the code is written in C #, easy to decompile, so the decision to extract the core algorithm part of the use of C + + writing, C + + so far seems to have not been very good decompile, of course, if you are a disassembly master, perhaps it is possible to decompile. This means that C # managed
