Good day,
I am using the .net client Apis and trying to setAsignee after retrieving a task. how to do it ?

I am using the below code
public static void AssginTask(string userName, string processInstanceId)
{
var camunda = CamundaBootstrap.CreateCamundaInstance();//custom code returns instance of camunda client object

        TaskQuery taskQuery = new TaskQuery { Active = true, ProcessInstanceId = processInstanceId };            

        var tasks = camunda.UserTasks.Query(taskQuery).List();
        var userTasks =  tasks.Result ;
        
        foreach (var item in userTasks)
        {
            item.// set assignee here ??
        }
    }

Thank you

@a-mubarak You can’t do querying task and updating task via same api either via rest endpoint or external task clients. Querying & updating task in same request is possible if process engine is embedded. For embedded process engine you can try like this,

execution.getProcessEngineServices().getTaskService().createTaskQuery().active().singleResult().setAssignee("myself");

For setting assignee for atask via rest api, you need to make rest api call to set-assignee or update-task api.

(OR)

Suppose, if process engine is embedded, it will work as you mentioned it.

Thanks you for your reply .

I managed to do it as the below code

using Camunda.Api.Client.ProcessDefinition;
using Camunda.Api.Client.ProcessInstance;
using Camunda.Api.Client.UserTask;

 public static async Task AssginTaskAsync(string userName, string processInstanceId)
        {
            var camunda = CamundaBootstrap.CreateCamundaInstance();           
            
            TaskQuery taskQuery = new TaskQuery { Active = true, ProcessInstanceId = processInstanceId };

            var tasks = camunda.UserTasks.Query(taskQuery).List();
            var userTasks = tasks.Result ;

            foreach (var item in userTasks)
            {
//Assign tasks to user demos
                await camunda.UserTasks[item.Id].SetAssignee(userName);                
            }
        }

[TestMethod()]
        public void AssginTaskAsyncTest()
        {
            new CamundaBootstrap("http://*******:8080/engine-rest", "demo", "demo");
            var tasks = TransactionManager.AssginTaskAsync("demo", "407c4669-257c-11ea-8a19-000d3a8b17c2");
            Assert.
        }

Thank you,
