A number guessing game using a flowchart

The flowchart was not invented in WF4. On the contrary, this type of diagram has a long history. The flowchart was first introduced by Frank Gilbreth in 1921 and he created a tool to use the flowchart in an industrial engineering curriculum.

As a programmer, you may already have experience in using a flowchart to draw an algorithm or process.

In this task, we will create a number guessing game using a flowchart. This task will also demonstrate the usage of the FlowDecision activity.

1. Create a workflow project:

   Create a Workflow Console Application and name it GuessNumberGameInFlowChart.

2. reate a ReadNumberActivity to receive the guess number:

   Create a new code file, name it ReadNumberActivity.cs ...
