ILMerge.AutoResolveMergedAssemblies

• IServiceTypeProvider - ServiceProvider for Types.
• ILMerge.AutoResolveMergedAssemblies

• Example of using ILMerge for dynamically loaded assemblies. You need use attributes in main assembly

  
  [assembly: AutoResolveMergedAssembliesAttribute(nameof(ILMerge.AutoResolveMergedAssemblies))]
  [assembly: AutoResolveMergedAssembliesAttribute("ILMergeDynamic.BaseModule")]
  [assembly: AutoResolveMergedAssembliesAttribute("Lobster.Home.DependencyInjection.ServiceTypeProvider")]
  
  void Main(string[] args)
  {
       AutoResolverInstaller.EnsureInstalled();
  }
