1 year ago Hey, this is because you're using protections which are working only with Mono runtime - specifically Unity, not a NET Core applications
When you see log in console at the start that says - 'Protection is intended for Mono' then don't use it, it's not compatible without specific runtime runned on top of the NET

1 year ago So how can I do it, please suggest me. Copy the BitMono.cs file in BitMono.Protections and put it in my project?

commented
1 year ago Simply install some of the mono versions, let's say the 5.2.0
After installation run the Mono.exe and provide path to your application, and it will be runned, iirc it work only with .exe files or make another dummy exe file and load your dll application via assembly load and reflection

1 year ago If I don’t need Mono runtime and just want the simplest obfuscation and protection, I try to enable only AntiILdasm, AntiDe4dot, and StringsEncryption, which are three options, and the other options are not enabled. The output log indicates success, but the program still cannot be started. Forgive my little knowledge about obfuscating and protecting dllfiles...T^T

1 year ago I guess it won't work because your application is .NET (Core) and the BitMono application is running on .NET Framework 462, to fix this issue we gonna need to add a .NET Core support in the BitMono as additional target framework
darkSuperman
commented
1 year ago Looking forward to supporting .NET (Core) earlier, .NET Framework is very old, and there are very few programs based on .NET Framework, thank you for your work. ：）

Hey, you need to obfuscate the .dll file which contains inside all managed code for .exe file, the .exe file is kinda compiled in native code
darkSuperman
commented
1 year ago I only confuse the dll, but there are some error logs in the console, and the obfuscated dll file is output, and the program cannot start using the obfuscated dll file. Please see the attachment for the log

1 year ago So interesting, will see what can be done to fix that

1 year ago and don't forget to use BitMono-v0.19.0-alpha.34-CLI-net6.0.zip, not a net framework build

commented
1 year ago I'm sorry to tell you that an error still occurs and the program cannot be started after obfuscation. Attach log files and protections.json files. bitmono-2023-10-12-17-26-45.log protections.json

Try to run the obfuscation only with AntiDe4dot, and test if the output file works (just for testing)
