    }
}

namespace SharedHostPolicy
{
    class SharedAssemblyResolver
    {
        public static Assembly LoadAssemblyFromSharedLocation(AssemblyLoadContext context, AssemblyName assemblyName)
        {
            string sharedAssemblyPath = ""; // find assemblyName in shared location...
            if (sharedAssemblyPath != null)
                return AssemblyLoadContext.Default.LoadFromAssemblyPath(sharedAssemblyPath);
            return null;
