.NET Core - C# - MacOS | Keychain API

Question

Trying to set/get some passwords into Keychain on MacOS, using C#. Managed to add Xamarin.iOS assembly, but can't seem to go further. This is what I have,

using System;
using Security;
using Foundation;

var query = new SecRecord(SecKind.InternetPassword)
{
    Server = "bugzilla.novell.com",
    Account = "miguel"
};

But get an exception, which isn't that useful. I am not sure what value is null. This above example is straight from Xamarin website, but doesn't work. New to this Keychain business, so not sure what I am missing.

Can someone help, please? Any help is greatly appreciated!

I have also tried to instantiate without the enum, but still get the same error.

Look at `SecKind.InternetPassword` [in your debugger](https://stackoverflow.com/questions/4660142/). — Dour High Arch, Jun 19 '18 at 20:32
@DourHighArch `SecKind.InternetPassword` is an enum - https://developer.xamarin.com/api/type/Security.SecKind/ — scorpion35, Jun 19 '18 at 20:34
Just found one [crappy] way - https://ss64.com/osx/security.html. Though crappy, it works! — scorpion35, Jun 20 '18 at 20:27

Was able to solve this by calling security cmd - https://ss64.com/osx/security.html

But if anyone knows how this can be done via API and using C#, please let me know.

You must properly initialize the Objective-C runtime as documented in Using Xamarin.Mac bindings for Console Apps before using Apple native APIs in C#:

NSApplication.Init();

Actually, calling ObjCRuntime.Runtime.EnsureInitialized(); would be enough but unlike NSApplication.Init(), the EnsureInitialized() method is internal and thus only callable through reflection, which is probably not a good idea.
