To set up gRPC preferences such as MaxReceiveMessageSize in .NET Framework, you can perform the following steps:

1. Define your gRPC server and client classes:

public class MyServer : MyService.MyServiceBase {...}

public class MyClient : MyService.MyServiceClient {...}

1. Create a gRPC server builder and configure the server options as follows:

var server = new Server { Services = { MyService.BindService(new MyServer()) }, Ports = { new ServerPort("localhost", Port, ServerCredentials.Insecure) },

// Set maximum receive message size
MaxReceiveMessageSize = 100 * 1024 * 1024

};

1. Create a gRPC client and configure the client options as follows:

var channel = new Channel("localhost", Port, ChannelCredentials.Insecure, new[] { new ChannelOption(ChannelOptions.MaxReceiveMessageLength, int.MaxValue) }); var client = new MyService.MyServiceClient(channel);

// Set maximum receive message size client.CallOptions = client.CallOptions.WithMaxReceiveMessageSize(100 * 1024 * 1024);

Note: In the above code, "Port" is the port number you want to use for your gRPC server.

With these steps, you can successfully set up gRPC preferences such as MaxReceiveMessageSize in .NET Framework.
