[.NET 8 COM support] CefSharp 120.1.110

[pieseczek]

Hi,
I would like to use CefSharp with the latest .NET 8.
I am using COM in my project. COM object is the client of CefSharp library, I am using CefSharp library in the constructor of the Foo class.
When I am creating the COM object, in the Foo constructor the exception is thrown:
_

System.IO.FileNotFoundException: 'Could not load file or assembly 'CefSharp.Core.Runtime, Version=120.1.110.0, Culture=neutral, PublicKeyToken=40c4b6fc221f4138'. The specified module could not be found.'
FileNotFoundException: Could not load file or assembly '\bin\x86\Debug\net8.0-windows\runtimes\win-x86\lib\netcoreapp3.1\CefSharp.Core.Runtime.dll'. The specified module could not be found.
_

I have run the same code with .NET 7 -> the same exception was raised.
The code is working successfully with .net48.

[assembly: ComVisible(true)]
namespace Foo
{
    [Guid("164ba864-95a5-4c15-8d72-8f6a325ce75c"),
    ComVisible(true),
    ClassInterface(ClassInterfaceType.AutoDispatch)]
    public class Foo
    {
        public Foo()
        {
            var settings = new CefSettings();
        }
    }
}

<PackageReference Include="CefSharp.WinForms.NETCore" Version="120.1.110" />
<PackageReference Include="CefSharp.Common.NETCore" Version="120.1.110" />

The COM object creation:

        var clsid = "{164ba864-95a5-4c15-8d72-8f6a325ce75c}";
        var type = Type.GetTypeFromCLSID(new Guid(clsid));
        var obj = Activator.CreateInstance(type, true);

Before running I have registered *.com.dll and verified that the GUID was added correctly in system registry,

Could you help me with these issue? Maybe some workaround could be applied?

I've never tried using CefSharp via COM, so the only advice I can give you is generic.

Make sure you've set a RuntimeIdentifier so you have an arch specific build.
