How to Update Windows Workflow Foundation Console Application?

Question

Basically here is my problem, I attached a WriteLine primitives on the designer, I input Hello World, then run it, it works perfectly fine.

Then I add an argument which you can see here, I deleted the Hello World message first, since I want to receive input from user.

Then on Program.cs, here is my basic code:

static void Main(string[] args)
    {
        // Get data from user, to pass to workflow.
        Console.WriteLine("Please enter the data to pass the workflow: ");
        string wfData = Console.ReadLine();

        // Package up the data as a dictionary.
        Dictionary<string, object> wfArgs = new Dictionary<string, object>();
        wfArgs.Add("MessageToShow", wfData);

        // Pass to the workflow.
        Activity workflow1 = new Workflow1();
        WorkflowInvoker.Invoke(workflow1, wfArgs);

    }

But after cleaning, and multiple rebuilds on my code, the same "Hello World" still appears on my system. I cannot input any data since its showing the previous WriteLine message that I have set. As you can see on the first image, I already deleted the message, and replace it with an argument namely "MessageToShow".

I am not sure if this is an error on Visual Studio 2015 Professional edition.

Copied your code and duplicated the workflow in VS 2017, and it works as you'd expect. If you haven't already done so, I'd suggest creating a new solution. — andyb

Try to manually delete the bin and obj folders in your solution. Sometimes VS gets out of sync with the designer changes you make.
