How to create proper autogenerated code in C# for gRPC?

Question

I created a proto file in a C# Project and tried to auto-generate C# codes by building the solution. But, I have an issue with the file under the extension grpc.cs.

''' 

/// <summary>Creates a new client for Greeter</summary>
   /// <param name="channel">The channel to use to make remote calls.</param>
      public GreeterClient(grpc::Channel channel) : base(channel)
      {
      }

'''

The above snip is from the example, where the public GreeterClient has the parameter (grpc::Channel channel) But in the below snip, it's (grpc::ChannelBase channel)

'''

/// <summary>Creates a new client for samples</summary>
/// <param name="channel">The channel to use to make remote calls.</param>
public samplesClient(grpc::ChannelBase channel) : base(channel)
{
}

'''

This throws an error telling 'Client Channel can't be found

How to configure and generate the grpc.cs file so that the parameter is (grpc::Channel channel)

Answer 1

I'm not sure what are you doing (...tried to autogenerate... <- you mean you running protoc manually ? Why ?)

This is an example for .NET Framework project, .NET Core created slight different - here is excelent resource to get started for .NET Core: ASP.NET Core gRPC for WCF Developers

Usually what you do

1. Create project and install relevant Nuget packages: Grpc, Grpc.Core and most importantly the Grpc.Tools package
2. Add new file. Name it whetever you want but extension must be .proto
3. Fill some data inside this proto file like:

syntax = "proto3";

option csharp_namespace = "MyNamespace";

...
...

4. Right mouse click on this file and select Properties
5. In the 'Properties' panel select Protobuf as a Build action. So it should look like this:

6. Rebuild the solution
7. Add another C# file, name it anything you want
8. In this C# file start referencing the structures you created in proto file. Like:

MyNamespace.MyServer server = new MyNamespace.MyServer()

but actually you should inherit from base class that ptotobuf created for you like this:

 public class GrpcImplementationClass: MyNamespace.MyServer.MyServerBase
 {

   public override MyFunction()
   {
   ...
   ...

P.S. There's a lot of tutorials for beginnners on Youtube
