"FileNotFoundException on Assembly WebEye.Stream.x64/32"/ .net core 3.1 using demo Stream.GetLocalStreams

[professordave]

Using the nuget version
WebEyeStreamControl.Wpf 1.0.3
WebEye.Stream 1.0.2

Hello, Copied the demo code into a working .net core 3.1 project. Instead of my original real main window, place this code into another new Main windows that gets shown by a button.

Click on button Add Local Stream
When the execution gets to the line from the demo:
public ObservableCollection LocalStreams { get; }
= new ObservableCollection(Stream.GetLocalStreams());

It throws a System.IO.FileNotFOundException.

System.IO.FileNotFoundException: 'Could not load file or assembly 'WebEye.Stream.x64, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.'

Tried forcing project to 32bit and 64bit and get the error for either the 64bit or the 32 bit assembly

I tried some code from the github repository
var path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory,
Environment.Is64BitProcess ? "WebEye.Stream.x64.dll" : "WebEye.Stream.Win32.dll");
var name = AssemblyName.GetAssemblyName(path);
return Assembly.Load(name).GetType("WebEye.ManagedWrapper");

And it seems to fail on the load, but the GetAssemblyName does succeed as the dll files are there

Hello, sorry, did not test it with .net core, try .net framework.

It is there for net40, which is compatible with net 4.5.2. Can you go to your output directory and check whether WebEye.Stream.x64.dll is in there?

[arteny]

no, it was absent in program output directory, now I switched app to .net 4.6.1 and it becomes working Best regards, Alexey Barkalov С уважением, Алексей Баркалов

Need to build Native project in 64 bit mode. And mostly you need Boost C++ library also 64 bit build
