I made a custom obfuscator and I haven't made any progress cracking it so please crack the file with my custom .NET obfuscator.

Do not use OllyDbg or any software of that kind, you can use Mega Dumper and other tools similar.

It's not good i think. Big file size, not encrypted strings or not emulated calls. Only bp true function and get valid serial.

Approach:

 

Spoiler
  1. Run app
  2. Attach windbg
  3. lm to get module address, !savemodule address dump.bin
  4. Open dump.bin in .NET disassembler/decompiler of choice, find main form button click handler, search call to TextBox::get_Text, observe serial in plaintext.
