DurableTask nuget 包升级到 2.0.0 版本后找不到 Azure 持久函数编排客户端

Azure durable function orchestration client cannot be found when the DurableTask nuget package is upgraded to version 2.0.0

定义一个队列触发函数,如下例:

public async Task OrchestratorAsync(
            [QueueTrigger("my-queue", Connection = "")]string payload,
            [OrchestrationClient] DurableOrchestrationClient orchestrationClient)
        {
            //Do something
        }

csproj 文件看起来像以下详细信息并且编译成功:


<PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
    <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.DurableTask" Version="1.8.2" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.Storage" Version="3.0.10" />
    <PackageReference Include="Microsoft.Azure.Functions.Extensions" Version="1.0.0" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.29" />
  </ItemGroup>
</project>

当我将 Microsoft.Azure.WebJobs.Extensions.DurableTask 升级到版本 2.0.0 时,编译器会抛出无法找到 OrchestrationClient 和 DurableOrchestrationClient 的错误。所以我们坚持使用 1.8.2 版!这个问题的解决方案是什么?

注意:这个问题在 VS 2019 中很容易重现。让它搭建一个函数项目,创建另一个函数作为持久协调器,调整 csproj 文件并将 DurableTask nuget 包版本从默认 1.8.2.

我已经重现了你的错误,我解决了这个问题。

        {
            var outputs = new List<string>();

            // Replace "hello" with the name of your Durable Activity Function.
            outputs.Add(await context.CallActivityAsync<string>("Function1_Hello", "Tokyo"));
            outputs.Add(await context.CallActivityAsync<string>("Function1_Hello", "Seattle"));
            outputs.Add(await context.CallActivityAsync<string>("Function1_Hello", "London"));

            // returns ["Hello Tokyo!", "Hello Seattle!", "Hello London!"]
            return outputs;
        }

        [FunctionName("Function1_Hello")]
        public static string SayHello([ActivityTrigger] string name, ILogger log)
        {
            log.LogInformation($"Saying hello to {name}.");
            return $"Hello {name}!";
        }

        [FunctionName("Function1_HttpStart")]
        public static async Task<HttpResponseMessage> HttpStart(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")]HttpRequestMessage req,
            [DurableClient]IDurableOrchestrationClient starter,
            ILogger log)
        {
            // Function input comes from the request content.
            string instanceId = await starter.StartNewAsync("Function1", null);

            log.LogInformation($"Started orchestration with ID = '{instanceId}'.");

            return starter.CreateCheckStatusResponse(req, instanceId);
        }
    }
}

解法:

将 [OrchestrationClient] 更改为 [DurableClient]。看看this。 请注意 Durable Functions v2.0.0-beta2 Release 中的重大更改,OrchestrationClient 已重命名。

我这边一切正常。请在你这边试一试。
