.net - Compiling C# to Native? -

-



i think i'm confused compiling .net byte-code native code, or maybe i'm confused end result. please bear me try sort through think understand can me figure out i'm missing.

what i'd compile application written in c# down regular native code i'd if had written in c. reasoning has nothing performance, rather degree of protection. understand end-goal not impossible (or difficult) circumvent, feel reversing x86 assembly more difficult reversing reflector gives me.

right if throw c# application reflector, source-code back. typically when throw unmanaged c/c++ applications idapro , use hexrays decompiler, don't quite same degree of decompilation , have resort wading through x86 disassembly understand logic flow. it's understanding such great decompilation comes reflector due application being in msil instead of more terse native code hexrays tries decompile.

i have no concerns client machine still needing .net runtimes, i'm not trying circumvent of that. run normal software obfuscation programs upx on program, , doing .net binary fails.

it understanding this related question ngen want. i've tried using ngen. after copying output file c:\windows\assemblies\...\applicationname.ni.exe directory somewhere can double-click, , trying run produces error not being "a valid win32 application". further, when toss applicationname.ni.exe reflector, same output did applicationname.exe. since applicationname.ni.exe supposed native code, expected reflector error out, didn't. if way i'm supposed this, why did reflector still give me such great decompilation?

so, summarize main question again: how can compile .net program native binary reflector won't decompile? or what's best practices protecting product written in .net language newbie reverse-engineers?

if need different tool, i'd prefer free , not codewall.

thanks!

update: understand i'm looking might limit of features of language reflection, think i'm fine that. none of code explicit assembly.load calls or of sort. couldn't replaced getprocaddress/loadlibrary calls anyway?

i validated .net native on vs2015 & windows 8.1 (when configured correctly, examine .proj validate) , building particular architecture (may overkill, haven't validated), produce native file give "harder reverse engineer" code looking me unabled read .dll via dotpeek(free .net decompiler jetbrains).

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
