Only BitTimeDateStamp, ObjectReturnType protection levels are working without any error for C# exe

[techei]

Description

Application I am trying to obfuscate is a complex one & it responsible to encrypt all files in configured directory. It is a C# exe so I can't use obfuscation protections compatible with Mono. I tried to use following protections but it makes dll unusable.

Only 2 protection configurations are usable for my use case, sharing my experiment results, let me know if I am missing something.

Protections which we planned to use : AntiDebugBreakpoints, BitTimeDateStamp, FullRenamer, StringsEncryption, AntiILdasm, AntiDe4Dot, BitMethodDotnet

Obfuscation Protections we are not using:

AntiDebugBreakpoints: not stable

FullRenamer: not stable

DotNetHook: MemberNotImportedException exception in-> some dll(s) refer logs attached

CallToCalli: MemberNotImportedException exception in-> MyApplication.dll, MyApplicationographer.dll, MyApplication.exe

BitMethodDotnet: run time error in event viewer

StringsEncryption: Protection encrypts strings using basic AES encryption, but not everyone like it because it makes the worse performance of application.

BitDotnet: Only compatible with Mono. Dnlib exploit & modifies the file metadata (PE) Unrecognizable for dnSpy

BitMono: Only compatible with Mono. Modifies th file metadata (PE) Unrecognizable for Detect It Easy.

AntiDecompiler: Only compatible with Mono. Sets non-public accessibility attributes according to ECMA(European Computer Manufactures Association) CIL(Common Intermediate Language) standard Old dnSpy will crash decompiling, latest version won't crash.

Only following protection levels can be used: BitTimeDateStamp, ObjectReturnType

How this issue is invalid @sunnamed434 ?

How this issue is invalid @sunnamed434 ?

Oh, its kinda I meant that not issue is invalid but specifically the problem that's happened is invalid, perhaps I would selected wrong issue tag

[sunnamed434]

So, most of the protection didn't work because of the wrong assembly resolve, soon will pre-release a new version, which should resolve the problem

[sunnamed434]

Forgot to send the message about that also, so, the problem should be fixed now, see

[sunnamed434]

Closing it due to inactive, for me problem is solved, I used different files and its fine! Feel free to reopen this
