add interface ,Set the default value of the ServerCallContext parameter to null. see code

using Greet;
using Grpc.Core;
using Surging.Core.CPlatform.Ioc;
using Surging.Core.CPlatform.Runtime.Server.Implementation.ServiceDiscovery.Attributes;
using System.Threading.Tasks;

namespace Surging.IModuleServices.Common
{
    [ServiceBundle("api/{Service}/{Method}")]
    public  interface IGreeterService : IServiceKey
    {
        Task<HelloReply> SayHello(HelloRequest request, ServerCallContext context=null);
    }
}

add GreeterBehavior, see code

using Greet;
using Surging.Core.CPlatform.Ioc;

namespace Surging.Modules.Common.GreeterServices
{
    public  partial class GreeterBehavior : Greeter.GreeterBase,IServiceBehavior
    {
        
    }
}

Add business module，see code

using Greet;
using Grpc.Core;
using Surging.IModuleServices.Common;
using Surging.Modules.Common.GreeterServices;

using System.Threading.Tasks;

namespace Surging.Modules.Common.Domain
{
    public class GreeterService: GreeterBehavior, IGreeterService
    {
        public override Task<HelloReply> SayHello(HelloRequest request, ServerCallContext context)
        {
            return Task.FromResult(new HelloReply
            {
                Message = "Hello " + request.Name
            });
        }
    }
}

client grpc test code:

using Greet;
using Grpc.Core;
using System;

namespace GrpcService1
{
    public class Program
    {
        public static void Main(string[] args)
        {
           var  channel = new Channel("127.0.0.1", 95, ChannelCredentials.Insecure);
           var client = new Greeter.GreeterClient(channel);
            var result = client.SayHello(new HelloRequest
            {
                Name = "fanly"
            });

            Console.WriteLine("grpc Client Call SayHello():" + result); 
            Console.ReadKey();
        } 
    }
}
