Obfuscator support for C# Features
Link Posted: 16-Jul-2021 02:46

It seems that the obfuscator does not like https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-8#default-interface-methods nor the ability to specify modifiers on interface methods (e.g. https://jeremybytes.blogspot.com/2019/11/c-8-interfaces-public-private-and.html). Both of these features where implemented for C# 8.

Resulting in errors:
[MD] Error: Non-public method in interface (token=0x02000034),
[MD] Error: Neither static nor abstract method in interface (token=0x02000070).
[MD] Error: Type:.class [XXX]YYY, token:0x020001ab, implemented interface:.class [XXX]ZZZ, token:0x01000088 but has no implemented method: [SomeMethod], token:0x06000150

Any way to exclude these interfaces from the obfuscation / validation process?
Kind Regards

Sorry for delayed response - vacation time :(
Thanks for the information and don't worry, this problem is currently on the way to be fixed.
PS: I'm not sure it would help to solve this situation if you exclude interfaces from obfuscation.

Thanks for the good news.

P.S. Am I right to assume that .NET 6 (and by extension, .NET Core) is not supported for obfuscation?

Spices.Net will provide full support of.Net6 and integration with VS2022 to the end of January.

That is great news indeed.

All of a sudden any interface implementation breaks during the obfuscation verification step, even for NetStandard2.0 assemblies :(

Consider for example a simple C# Project:

<Project Sdk="Microsoft.NET.Sdk">

With a single CS file:

namespace ClassLibrary;
public interface IThing
  void DoThis();
  void DoThat();
public sealed class Thing : IThing
  public void DoThis() { }
  void IThing.DoThat() { }

NRObfuscator.exe /RESOLVEORSKIP /SRC=ClassLibrary.dll /OUT=ClassLibrary.Obfuscated.dll

Results in 2 verification errors:
[MD] Error: Static method in interface (token=0x02000002).
[MD] Error: Static method in interface (token=0x02000002).

Unable to use the new release to obfuscate my code :(

I can confirm that the latest release resolves my (and the other user on this thread, which is also me:)'s) issues.

Thank you very much!
