Do Work

Describe the bug I work with devcontainer. If I use the devcontainer below i get this error:

System.DllNotFoundException : Unable to load shared library 'pact_ffi' or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable: /usr/share/dotnet/shared/Microsoft.NETCore.App/7.0.19/pact_ffi.so: cannot open shared object file: No such file or directory

        _pactBuilder = pact.UsingNativeBackend();
    }

    [Fact]

            .UponReceiving("a request")

            .WillRespond()
                .WithStatus(HttpStatusCode.OK);

        await _pactBuilder.VerifyAsync(async ctx =>
        {
            var client = new HttpClient { BaseAddress = ctx.MockServerUri };

            var response = await client.GetAsync("/");

            response.EnsureSuccessStatusCode();
        });
    }
}

Expected behavior Pass the test and create the pact file

Additional context If I launch this devcontainer in a Mac with Intel x64, it works. If I launch this devcontainer in a Mac with ARM M2, it does not work. If I launch this test locally in a Mac with ARM M2, it works.

Mac ARM isn't supported in 4.x. Support is added from 5.0.0-beta.2 onwards. See https://github.com/pact-foundation/pact-net/issues/451#issuecomment-1946712324
