can you support automatic load of SAP NetWeaver RFC Library DLL?

can you support automatic load of SAP RFC Native Library DLL? such as : win64>icudt50.dll/icuin50.dll/icuuc50.dll/libicudecnumber.dll/libsapucum.dll/sapnwrfc.dll linux64>libicudata.so.50/libicudecnumber.so/libicui18n.so.50/libicuuc.so.50/libsapnwrfc.so/libsapucum.so

Sorry, I’m lost in your issue. Libsapnwrfc is load by NwRfcNet, other libs are directly by Libsapnwrfc. What is your issue exactly ?

I hope to automatically load native DLL according to different platforms; code example： internal class PlatformDlls { public string Path { get; set; } public string[] DllNames { get; set; } }

    static UnsafeNativeMethods()
    {
        PlatformDlls libraryInfo = GetNativeLibraryInfo();
        var path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
        foreach (var dll in libraryInfo.DllNames)
        {
            var dllPath = Path.Combine(path, "Native", libraryInfo.Path, dll);
            NativeLibrary.Load(dllPath);
        }
    }

    private static PlatformDlls GetNativeLibraryInfo()
    {
        PlatformDlls platformDlls = new PlatformDlls();
        if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows)
            && (RuntimeInformation.ProcessArchitecture == Architecture.X64))
        {
            platformDlls.Path = "Win64";
            platformDlls.DllNames = new[] {
            "icudt50.dll",
            "icuin50.dll",
            "icuuc50.dll",
            "libicudecnumber.dll",
            "libsapucum.dll",
            "sapnwrfc.dll"
        };
        }
        else if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows)
            && (RuntimeInformation.ProcessArchitecture == Architecture.X86))
        {
            platformDlls.Path = "Win32";
            platformDlls.DllNames = new[] {
            "icudt50.dll",
            "icuin50.dll",
            "icuuc50.dll",
            "libicudecnumber.dll",
            "libsapucum.dll",
            "sapnwrfc.dll"
        };
        }
        else if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux)
            && (RuntimeInformation.ProcessArchitecture == Architecture.X64))
        {
            platformDlls.Path = "Linux64";
            platformDlls.DllNames = new[]
            {
            "libicudata.so.50",
            "libicudecnumber.so",
            "libicui18n.so.50",
            "libicuuc.so.50",
            "libsapnwrfc.so",
            "libsapucum.so"
        };
        }
        else if (RuntimeInformation.IsOSPlatform(OSPlatform.OSX))
        {
            platformDlls.Path = "OSX";
            platformDlls.DllNames = new[] {
            "libicudata.50.dylib",
            "libicudecnumber.dylib",
            "libicui18n.50.dylib",
            "libicuuc.50.dylib",
            "libsapnwrfc.dylib",
            "libsapucum.dylib"
        };
        }
        else
        {
            throw new Exception("Unsupported OSPlatform, can't locate sapnwrfc library.");
        }

        return platformDlls;
    }

This issue isn't related to paths and environment variable LD_LIBRARY_PATH ? SO’s tries to load library in defined folders. In Linux searches for libraries in folder application folder and folders defined in LD_LIBRARY_PATH. Do you get a particular error when using this library ? I have made a test and Linux and libraries where load properly. I have placed all libraries in the same folder.

Output from "ls -la" command in linux
