gRPC StarLink Router .Net

Question

New Info:

I thought I would paste this in full as I can not seem to find any samples on the web of a c# solution for StarLink so hopefully anyone else looking for something may find this helpful and may contribute.

My New Proto File - (partial) - I took the advise of Yuri below. Thanks for the direction here. I was able to I have been using this tool and it has brought a lot of insight but I am still stuck on the c# side of the solution. I am an old VB.Net developer though I have done a bunch in c# I am by no means savvy in it and am probably missing something so simple. Again, any insight would be awesome. I can not post the full proto here as stack has char limit on posts. this is the first bit with messages etc. I can post more if it helps but trying to keep it to the important part.

    syntax = "proto3";

    option csharp_namespace = "SpaceX.API.Device";

    package SpaceX.API.Device;


    service Device {
        //rpc Handle (.SpaceX.API.Device.Request) returns (.SpaceX.API.Device.Response) {}
        //rpc Stream (stream .SpaceX.API.Device.ToDevice) returns (stream .SpaceX.API.Device.FromDevice) {}
        rpc Handle (Request) returns (Response);
        rpc Stream (Request) returns (Response);
    }

    message ToDevice {
        string message = 1;
    }

My New .cs I have tried many things from Microsoft's examples to thing I can gather from other samples. I simply can not get it to work and am lost. Again, any insight would be amazing and hopefully helpful to others looking for a solution in c#. You will see my commented code of this I have been playing with. Basically I am attempting to achieve three things and have made some movement in one of them.

Goals:

1 - Use Server Reflection to discover services. I think I got this one resolved with dot-net grpc.

2 - Simply want to check available methods under a service and potentially either check or generate a new .proto file in case things change. StaLink does not publish its proto schema so I assume it could change anytime without warning.

3 - Just run any one of the available methods. I have tried the GetDeviceInfoRequest but can not seem to construct the request message properly. I have not been able to get this accomplishe in the gRPCurl tool either. I can do it on the basic service shown by Microsoft of course but these methods seem to be more complex and I simply get all kinds of errors.

Again, any insight or assistance would be amazing. Thanks to any and all in advance.

Again, thanks in advance to anyone willing to assist here. Hopefully this helps others as well.
