Exception "Creating an instance of the COM component with CLSID" when creating new object

I have C# project which i'm publishing using IIS. Tried to debug webPage and found that on code line

var SilApi = new SilApi();

webPage got stuck and it's keep loading something. After 10-20 min, it's stop loading and error appears.

Creating an instance of the COM component with CLSID {AD0C0100-CE10-11DE-8F7A-005056C00008} from the IClassFactory failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).

Any ideas?

This is how SilApi looks like:

using System.Runtime.InteropServices;

namespace SilApi 
{
    [CoClass(typeof(SilApiClass))]
    [Guid("AD0C0001-CE10-11DE-8F7A-005056C00008")]
    public interface SilApi : ISilApi 
    {
    }
}

This is how ISilApi looks like:

using System.Runtime.InteropServices;

namespace SilApi  
{
    [Guid("AD0C0001-CE10-11DE-8F7A-005056C00008")]
    [TypeLibType(4160)]
    public interface ISilApi  
    {
        [DispId(1)]
        ISilDocumentFactory SilDocumentFactory { get; }
        [DispId(2)]
        ISilPackageFactory SilPackageFactory { get; }
        [DispId(5)]
        ISilSpecificationFactory SilSpecificationFactory { get; }
       <....>
        [DispId(6)]
        IX509CertificateFactory X509CertificateFactory { get; }

        [DispId(33)]
        IMap GetNewMap();
    }
}
