Using AxWindowsMediaPlayer control on MONO c#

I try to make a AxWindowsMediaPlayer control on form whit MONO on raspian. It work very well on Windows, but on Raspian I have this error:
"System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'Hmi800App.PlayerVideoForm'.
at System.Windows.Forms.Control.CreateHandle () [0x00013] in <28e46de2d20c496895000ef0abfc2106>:0

Can you halp me?

System.DllNotFoundException: libpcsclite.so.1 assembly:<unknown assembly> type:<unknown type> member:(null)

Researched this issue many times but didn't found solution of it. Working with xamarin forms version 5.0.0.2012, on win 10 os (saw many solutions for mac or linux but didn't found any for windows), using PCSC library version 5.0.0. Trying to invoke context.Establish method while debugging on Android 8.0:
public SimpleReader(ISCardContext context, bool releaseContextOnDispose = false)
{
if (context == null)
{
context = (ISCardContext) new SCardContext();
context.Establish(SCardScope.System);
releaseContextOnDispose = true;
}
this._context = context;
this._reader = (ISCardReader) new SCardReader(context);
this._releaseContextOnDispose = releaseContextOnDispose;
this._disconnectReaderOnDispose = true;
}
When, exception occur with message below:

Does anyone faced with this issue?

The PCSC library does not appear to explicitly support Android. In my experience, nugets that work with Xamarin.Android have explicit dependencies set for the platform, but this one does not.
The library tries to use P/Invoke wrappers around native code. You can see that there are implementations for a number of operating systems here, but I don't see any references to Android. The stack trace shows that the code is deciding to use the Linux wrapper, which makes sense. It's looking for the libpcsclite.so.1 native "C/C++" library, but it's not finding it. That library has a home page that does not reference Android.
The PCSC nuget docs state:
pcsc-sharp does not contain any device drivers. A PC/SC compliant
reader + driver is mandatory.
That's the libpcsclite.so.1 . Either your Android device doesn't provide it, or if it does, it's not in a location that your Android app can find it. My Android device (running Android 9) does not have that library in any of /system/*lib* directories, which means that at least for my device someone would need to compile that native library for the CPU (usually arm64) for the device. If you can either compile the native code yourself or find someone who has, AND the native code supports the reader on your Android device, then you could get the whole thing to work.
I don't have any experience with PCSC myself - just some experience with Xamarin and native libraries.

Unit testing of Realm in Xamarin iOS

Xamarin iOS native app. I have to write unit test for Realm api. It is the layer with ability to filter data. It can contain complicated Linq queries, so testing is necessary.
For instance, method:
Task<List<T>> Get(int count, int type, int? id);
Creating NUnit test I need to get Realm object:
var realm = Realm.GetInstance(new InMemoryConfiguration("test"));
but getting an exception:
System.TypeInitializationException : The type initializer for 'Realms.SharedRealmHandle' threw an exception.
----> System.DllNotFoundException : realm-wrappers assembly:<unknown assembly> type:<unknown type> member:(null)

So, main point that I can't create Realm instance.
Is launched iphone simulator necessary to work with Realm?
Are there some possibility to create unit tests for Realm?
Or should it be some kind of Auto tests?

As I found, solution is iOS Unit Test App (Solution -> Add -> New Project -> iOS -> Tests -> Unit Test App).
There are few disadvantages, but it is possible to test Realm. The next challenge is to run it and get result with TeamCity.

How to change architecture of .ipa or .app from arm64 to i386 without source code

I'm writing mobile autotests using C#, Xamarin 6.1.3, iOS 10.2, iPhone 6s Plus, Xcode 8.2, OS X El Capitan 10.11.6.
I'm trying to launch tests on simulator using the following command:
IApp iApp = ConfigureApp.iOS.AppBundle(path_to_app/Application.app).StartApp();
I've got the following error:

Ios simulator supports only i386 architecture, as I know it cannot be changed.
Is it possible to change architecture of application, if I don't have source code, just .ipa and .app files?

It is not possible to change the supported architecture of an .ipa or an .app without the source code.
