Error compiling Autorest Generated Client

Question

After autogenerating client using Swagger OpenApi 3.0 spec, I'm unable to compile the generated client. I get error on objects ClientDiagnostics, RawRequestUriBuilder, Utf8JsonRequestContent.

RestClient.cs

using System;
using System.Collections.Generic;
using System.Text.Json;
using System.Threading;
using System.Threading.Tasks;
using Azure;
using Azure.Core;
using Azure.Core.Pipeline;
using Planner.Client.Models;

namespace Planner.Client
{
    internal partial class RestClient
    {
        private Uri endpoint;
        private ClientDiagnostics _clientDiagnostics;
        private HttpPipeline _pipeline;

        /// <summary> Initializes a new instance of RestClient. </summary>
        /// <param name="clientDiagnostics"> The handler for diagnostic messaging in the client. </param>
        /// <param name="pipeline"> The HTTP pipeline for sending and receiving REST requests and responses. </param>
        /// <param name="endpoint"> server parameter. </param>
        public RestClient(ClientDiagnostics clientDiagnostics, HttpPipeline pipeline, Uri endpoint = null)
        {
            endpoint ??= new Uri("https://localhost:49157");

            this.endpoint = endpoint;
            _clientDiagnostics = clientDiagnostics;
            _pipeline = pipeline;
        }


        internal HttpMessage CreateCreateDataRequest(IEnumerable<DataCreateModel> body)
        {
            var message = _pipeline.CreateMessage();
            var request = message.Request;
            request.Method = RequestMethod.Post;
            var uri = new RawRequestUriBuilder();
            uri.Reset(endpoint);
            uri.AppendPath("/api/Budget/CreateData", false);
            request.Uri = uri;
            if (body != null)
            {
                request.Headers.Add("Content-Type", "application/json");
                var content = new Utf8JsonRequestContent();
                content.JsonWriter.WriteStartArray();
                foreach (var item in body)
                {
                    content.JsonWriter.WriteObjectValue(item);
                }
                content.JsonWriter.WriteEndArray();
                request.Content = content;
            }
            return message;
        }
    }
}

Also, getting error in below autogenerated serialization class on IUtf8JsonSerializable and Optional.

        {
            writer.WriteStartObject();
            if (Optional.IsDefined(ProjectCode))
            {
                if (ProjectCode != null)
                {
                    writer.WritePropertyName("projectCode");
                    writer.WriteStringValue(ProjectCode);
                }
                else
                {
                    writer.WriteNull("projectCode");
                }
            }
            if (Optional.IsDefined(TeamCode))
            {
                if (TeamCode != null)
                {
                    writer.WritePropertyName("teamCode");
                    writer.WriteStringValue(TeamCode);
                }
                else
                {
                    writer.WriteNull("teamCode");
                }
            }
            if (Optional.IsDefined(YearMonth))
            {
                writer.WritePropertyName("yearMonth");
                writer.WriteNumberValue(YearMonth.Value);
            }
            if (Optional.IsDefined(Hours))
            {
                writer.WritePropertyName("hours");
                writer.WriteNumberValue(Hours.Value);
            }
            writer.WriteEndObject();
        }
    }
}

This project using .net 5, autorest v3.1.0, cli v3.1.2 and node v14.15.5.

What am I missing?

Answer 1

I have add only this changes and it works

<PropertyGroup>
  <IncludeGeneratorSharedCode>true</IncludeGeneratorSharedCode>
  <RestoreAdditionalProjectSources>https://azuresdkartifacts.blob.core.windows.net/azure-sdk-tools/index.json</RestoreAdditionalProjectSources>
</PropertyGroup>

<ItemGroup>
  <PackageReference Include="Azure.Core" Version="1.10.0" />
  <PackageReference Include="Microsoft.Azure.AutoRest.CSharp" Version="3.0.0-beta.20210311.1" PrivateAssets="All" />
</ItemGroup>

For the client creation i use this

class MyClientOptions : ClientOptions
{
}

static void Main(string[] args)
{
    var client = new TestRestClient(
        new ClientDiagnostics(new MyClientOptions()),
        new HttpPipeline(HttpClientTransport.Shared),
        new Uri("https://api.domain.com"));
}
