Introduction
A workflow is a series of distinct programming
steps or phases. Each step is modeled in WF as an Activity. It has been
completely reengineered from the ground up. It is a way to execute business
processes and in today's applications supporting business processes we are
frequently using Windows Workflow technologies as the key technical solution.
A key component of workflow design is the use
of extensions to configure the environment in which the workflow activities
operate, the .NET Framework provides a library of activities and custom
activities can also be developed for additional functionality. The Workflow
Designer is built using Windows Presentation Foundation (WPF). This enhances the
activity designer experience and improves performance for large and complex
workflows.
Some of the major criteria for workflows are
listed below:
- Visual Representation of process
- Can be dynamically modified at run-time
- Can be long-running
Activities can be assembled visually into
workflows using the Workflow Designer, a design surface that runs within Visual
Studio. The designer can also be hosted in other applications.
Getting Started:
Step 1: Start Visual Studio 2010 and
select the New Project and choose Workflow Console Application give name in my
case HelloWorld
The application generates a Program.cs file and
Workflow1.xaml file which is used for the console application and workflow
Step 2: First go to Workflow1.xaml file
initial it is empty, drag a WriteLine activity
Step 3: Go to the properties of
WriteLine activity and insert the value
Step 4: Go to the Program.cs file and
modify the code like below
using
System;
using
System.Linq;
using
System.Activities;
using
System.Activities.Statements;
namespace
HelloWorld
{
class Program
{
static void
Main(string[] args)
{
WorkflowInvoker.Invoke(new Workflow1());
Console.WriteLine("Press
ENTER to exit");
Console.ReadLine();
}
}
}
Step 5:
Run the application
Output
Press Enter to exit the
application output
