Change a network transport: reimplementing LinqService?

I’m looking to https://github.com/linq2db/examples/tree/master/LinqOverWCF/Windows Host and trying to replace wcf -> grpc.

I’m at the beginning and need an advise or someone who give me right direction. My trouble now is to understand - I need to take LinqService as is and wrap it with grpc stuff and grpc DTO objects I need to create, or I need to reimplement it.

I tried to reimplement because I want to have all methods (ExecuteReader, ExecuteBatch etc) as async. So instead of

                return DataConnection.QueryRunner.ExecuteNonQuery(db, new QueryContext
                {
                    Statement = query.Statement
                }, new SqlParameterValues());

I want to have

                return await DataConnection.QueryRunner.ExecuteNonQueryAsync(db, new QueryContext
                {
                    Statement = query.Statement
                }, new SqlParameterValues());

etc. Here is a problem: LinqServiceSerializer, DataConnection.QueryRunner and others is internal. of course I can overcome in with reflection, but I’m not sure it’s a right direction.

Any advices will help me a lot. Thanks!

We don’t have date for final release of v4 except this year, but we release v4 previews from time to time. Maybe I will find time to include requred changes in nearest preview

There were never declared compatibility between different versions of server and client as we transfer serialized AST and it changes a lot between versions with each new feature
