Core.System.ServiceProcess

Support System.Configuration.Install for .NET Core / .NET 5+. Used version from Microsoft Reference Source and comments from .NET Framework DLL v4.0.0.0.

Usage / Documentation

Fixing the ImagePath in the Registry

Somewhere in your parent installer, you will need to correct the path for the ServiceInstaller's assemblyPath (non-case sensitive). With .NET Framework, the entry assembly was always an exe. However, even when running the exe dropped out with a publish, it just bootstraps the DLL and your ImagePath gets written to the registry with a .dll suffix, which will not work on startup (crashes in KERNELBASE.dll).

Use something like this after whatever is setting your assemblyPath today:

private void CorrectAssemblyPath(InstallContext context)
{
    string possibleDll = context.Parameters["assemblyPath"];

    if (possibleDll == null)
    {
        return;
    }

    if (possibleDll.EndsWith(".dll", StringComparison.OrdinalIgnoreCase))
    {
        var exe = possibleDll.Substring(0, possibleDll.Length - 4) + ".exe";
        context.Parameters["assemblyPath"] = exe;
    }
}

Assembly Filename

The assembly had to be renamed to System.ServiceProcess.Core.dll because the .NET Core pack comes with an empty (based on analysis with dnSpy) System.ServiceProcess.dll which causes the build to fail by saying none of the types are valid (assembly not referenced error). The compiler does not complain about the two DLLs and just silently ignores the new one.

I renamed it, but all the types are still in the original namespace so this should not affect your code.

---

More documentation would be appreciated via PRs, but this library is only for backward compatibility with .NET Framework applications being brought into .NET Core and .NET 5+, so it should not be used for new projects.

The interactive service credential prompt is only available when targeting .NET Core 5.0-windows+ since System.Windows.Forms is unavailable in .NET Standard 2.0. This functionality is untested (by me).
