how to return `Task<HttpResponseMessage>` as true/false value

I want to return true/false for Task<HttpResponseMessage>, how to do this.

Currently I'm getting below error here,

cannot convert from 'bool' to 'System.Func< System.Net.Http.HttpResponseMessage>'

private Task<HttpResponseMessage> PersistData()
    {
        Trace.TraceError("test");
        return new Task<HttpResponseMessage>(true);
    }

update:

I want to return Task<HttpResponseMessage> with some empty or whatever, how to do this.

private Task<HttpResponseMessage> PersistData()
    {
        Trace.TraceError("test");
        //what to return here?
    }

You can not return True/False exactly, but you can handle this issue by bottom code.

Private Task<HttpResponseMessage> PersistData()
    {

        Trace.TraceError("test");

        return new Task<HttpResponseMessage>(() => new HttpResponseMessage(HttpStatusCode.Accepted));
    }

And after that you can check if HttpStatuseCode was "HttpStatuseCode.Accepted" its mean true OR another things. same this,

   Private bool Validation()
    {
        var temp = PersistData();

        if (temp.Result.StatusCode == HttpStatusCode.Accepted)
            return true;
        else 
            return false;
    }

You can't return true or false for HttpResponseMessage, but you can change your type of return value.

private Task<bool> PersistData()
 {
    Trace.TraceError("test");
    return Task.FromResult(true)
 }

updated not async

private HttpResponseMessage PersistData()
{
    Trace.TraceError("test");
    return new HttpResponseMessage(HttpStatusCode.OK);
}

async

 private Task<HttpResponseMessage> PersistData()
        {
            Trace.TraceError("test");
            return Task.FromResult(new HttpResponseMessage(HttpStatusCode.OK));
        }

You can return the empty string using below code:

return Task.FromResult(Request.CreateResponse(HttpStatusCode.OK, string.Empty));

Here Request.CreateResponse is extension method which creates HttpResponseMessage. You can read the documentation at here.

You can read about Task.FromResult at here.
