orleans: .NetCore2.0 Runtime Codegen fail in Orleans TechPreview3 (reopen issues #3404)

When I build a .net core 2.0 application with Orleans , I already add reference Orleans.OrleanCodeGenerator to my Client and Server , but the orleans silo server not load the grains dll , and occur this error :

Unhandled Exception: System.ArgumentException: Cannot find an implementation class for grain interface: Orleans.Interface.IPlayerGrain. Make sure the grain assembly was correctly deployed and loaded in the silo.
   at Orleans.GrainFactory.GetGrainClassData(Type interfaceType, String grainClassNamePrefix)
   at Orleans.GrainFactory.GetGrain[TGrainInterface](Int64 primaryKey, String grainClassNamePrefix)
   at Orleans.Client.Program.Main(String[] args) in C:\Users\Administrator\Documents\visual studio 2017\Projects\OrleansCore\Orleans.Client\Program.cs:line 14

thats my code :

Interface :

    public interface IPlayerGrain : IGrainWithIntegerKey
    {
        Task SayHello(string content);
    }

Grain :

    public class PlayerGrain : Orleans.Grain  , IPlayerGrain
    {
        public Task SayHello(string content)
        {
            Console.WriteLine($"Say {content} to {this.GetPrimaryKeyLong()}");
            return Task.CompletedTask;
        }
    }

Client :

    var config = ClientConfiguration.LocalhostSilo();
    GrainClient.Initialize(config);
    var player = GrainClient.GrainFactory.GetGrain<IPlayerGrain>(1000);
    player.SayHello("Hi!!!");
    Console.WriteLine("Press any key to terminate!");
    Console.ReadKey();

Server:

    var config = ClusterConfiguration.LocalhostPrimarySilo();
    var siloHost = new SiloHost("Orleans",config);
    siloHost.InitializeOrleansSilo();
    siloHost.StartOrleansSilo(true);
    Console.WriteLine("Press any key to terminate!");
    Console.ReadKey();

In issues #3404 , I made a mistake that the PlayerGrain have not inherit Orleans.Grain class , then I fixed it , but the the problem still occurs . Has another one has this issues ? @ReubenBond @Cherrs 我不知道该怎么联系你，希望你能看到 ，你的 测试用例，我用VS2017运行之后还是出现这个问题
