WF Samples

Rules Driven Pageflow

jamescon — Wed, 26 Mar 2008 23:48:26 GMT

Resource Description

Windows Workflow Foundation (WF) offers rules capabilities to the NetFx developer platform. RuleSets are collection of business rules with conditions and actions and they can be executed on any target object such as a Web application. In this sample we will show the stand alone functionality of rules in driving the page flow for a simple ASP.NET application.

Sample Usage

Run the setup.cmd provided with the ExternalRuleSetToolkit sample here. This setup batch file will create Rules database on SQL Express and setup the Ruleset Table. This is a prerequisite to use this sample.
Open the WebSite and publish it to a specified location. For example - C:\inetpub\wwwroot\HelpDeskSupport\. This will create the application dll.
Run the provided InsertRulesDrivenPageFlow.cmd which will invoke InsertRulesDrivenPageFlow.sql script. The script file will insert the serialized form of rulesets associated with this sample in the Ruleset Table created in the previous step.
Note that script assumes that App_Web_tsypxcth.dll (application dll - The dll name can vary and hence change the SQL script accordingly) is located at C:\Windows Workflow Foundation\bin\ and ExternalRuleSetToolkit validates this location. Please edit the InsertRulesDrivenPageFlow.sql script to include the desired path\name for the application dll before you run it.
Run the solution and navigate through the pages by entering appropriate data wherever possible.
Run the ExternalRuleSetToolkit sample to view the HelpDeskSample rules stored in the database.
The connection to the database is defined in the Logic.cs and InsertRulesDrivenPageFlow.cmd. If you wish to use a different database server, please change the connection in both places.

This codeplex project aims to provide "a fully functional generic persistence and tracking service with ADO implementations for SQL Server, Oracle and MySQL"

DinnerNow (.NET 3.0)

mwink — Thu, 15 Nov 2007 18:21:17 GMT

DinnerNow is a fictitious marketplace where customers can order food from local restaurants for delivery to their home or office. This sample is designed to demonstrate how you can develop a connected application using several new Microsoft technologies.

The demo utilizes several technologies including: IIS7, ASP.NET Ajax Extensions, LINQ, Windows Communication Foundation, Windows Workflow Foundation, Windows Presentation Foundation, Windows PowerShell, and the .NET Compact Framework.

This sample is based on the .NET Framework 3.0

DinnerNow (.NET 3.5)

mwink — Thu, 15 Nov 2007 18:19:33 GMT

This version is based on the .NET Framework 3.5

UServ Product Derby End To End Rules Sample

mwink — Thu, 15 Nov 2007 18:15:30 GMT

The UServ Product Derby is an end-to-end scenario sample based on the UServ Product Derby Case Study used at the Business Rules Forum. In this sample, the WF Rules Engine is used to model the rules for some key scenarios in this case study and perform the processes in the company such as -

Verification and approval of a new client application
Determine the eligibility of a client to obtain vehicle insurance
Determine the Premium for Vehicle Insurance

Processing XML with WF Rules

mwink — Thu, 15 Nov 2007 18:10:25 GMT

This sample shows how the WF Rules Engine can be used to process rules on Xml Documents.

Custom Rule Actions

mwink — Thu, 15 Nov 2007 18:08:09 GMT

This sample shows how custom rule actions (derived from the RuleAction Type) can be defined and used in the Windows Workflow Foundation rules engine. Three sample rule actions are provided which demonstrate how to perform the following actions from a rule:

Write text to the console
Execute a RuleSet
Queue an activity for execution

Custom Rule Expressions

mwink — Thu, 15 Nov 2007 18:07:36 GMT

This sample shows the definition and use of a custom expression in the Windows Workflow Foundation rules engine. Custom expressions are used to model specific predicate types or functions and can be used directly in the rules object model and editors

Creating Rules Using the Object Model

mwink — Thu, 15 Nov 2007 18:05:51 GMT

This sample shows how to use the Windows Workflow Foundation (WF) Rules Object Model to create Rules directly using the APIs without using the designers. The rules created are then executed by the WF Rules Engine.

Rules Driven UI with Tracing

mwink — Thu, 15 Nov 2007 18:00:21 GMT

Windows Workflow Foundation (WF) offers rules capabilities to the .NET Framework 3.0 developer platform. RuleSets are collection of business rules with conditions and actions and they can be executed on any target object such as a Windows Form. This sample is a modification of the Rules Driven UI Sample where I added capabilities to show how you can utilize the System.Diagnostics traces to get information about rules execution. For more information on this specific modification, check WF Rules Execution Tracing blog post.

Rules Driven UI

mwink — Thu, 15 Nov 2007 18:00:17 GMT

Windows Workflow Foundation (WF) offers rules capabilities to the WinFx developer platform. RuleSets are collection of business rules with conditions and actions and they can be executed on any target object such as a Windows Form. In this sample we will demonstrate this capability by using rulesets to pre-populate fields, do cross validation and various calculations on a target Windows Form. We will also show rules features such as forward chaining in this sample.

Collection Processing with Rules

mwink — Thu, 15 Nov 2007 17:56:47 GMT

This sample illustrates the execution of rulesets against a collection of objects. This makes use of the techniques outlined in the Windows SDK documentation filed in the Processing Collections.

This Windows Forms application will execute a ruleset against either an array of objects, or against a collection of them. For additional information on how this sample works, please see my blog post on the topic.

Steps to get the application to work:

Download and extract the RulesWithCollectionSample
Open the RulesWithCollectionSample solution and build it
Download and extract the External RuleSet Toolkit, and create a rules database.
Import the rules from the .rules file in the RulesWithCollectionSample folder (you will need to point it to the assemblies of the RulesWithCollectionSample solution that you just built)
Save this to the rules database
Make sure the app.config file points to the right rules database.
Hit F5 to run, and you will be able to add numbers in one of two ways (via an array or a collection of objects)

Ruleset Analyzer

mwink — Thu, 15 Nov 2007 17:54:26 GMT

This sample uses the rules object model to analyze dependencies and execution plans for a ruleset. This is a useful sample to debug and diagnose a complex ruleset.

External Ruleset Toolkit

mwink — Thu, 15 Nov 2007 17:53:55 GMT

This sample was put together by the rules team to illustrate how rules can be externalized outside the workflow and live inside a SQL server. This also shows how to rehost the rules designer, and execute the rule set outside of a WF.
