WCF RIA - Design Technique for CRUD many-to-many relationships

Posted By:      Posted Date: September 07, 2010    Points: 0   Category :WCF
In summary, what is the best development technique for updating many-to-many entity relationships where you are inserting two of three entities in the same functional transaction and using Silverlight 4 w/ WCF RIA & SQL Server 2008? The entities are "category", "link" and "category-link-xref". A category can have many links and a link can be associated with many categories.  In the GUI when creating a "link" record I am trying to decide the best method of inserting the "category-link-xref" record along with it.  Should I let WCF RIA do the Insert of "link" and add logic to the DS class to add the category-link-xref row? Does WCF RIA have anything built in for this type situation, or am I better off just adding code to the domain services class for inserting the associative table, or maybe a stored procedure would be better? Any guidance, tips, or sample code greatly appreciated! Regards, Rich

Solidify Your C# Application Architecture with Design Patterns

design pattern can solve many problems by providing a framework for building an application. Design patterns, which make the design process cleaner and more efficient, are especially well-suited for use in C# development because it is an object-oriented language. Existing design patterns make good templates for your objects, allowing you to build software faster. This article describes several popular design patterns you can use in your own applications, including the singleton, the decorator, the composite, and the state classes, which can improve the extensibility of your applications and the reuse of your objects.

What Are Design Patterns and Do I Need Them?

Software professionals may be familiar with the term "Design Patterns," but many have no idea of where they come from and what they truly are. Consequently, some do not see the value and benefits design patterns bring to the software development process, especially in the areas of maintenance and code reuse.

Design Patterns for .NET

It is not the intent of the Design Pattern Series to focus on providing a theoretical knowledge dump of all there is to know about design patterns. There are many books that do that already. Instead, this series will focus on providing lots of practical examples. However, there will be some theory to help address important points concerning design patterns. I use the theory of design patterns mostly as a guide and instead make references to good design pattern books for more detail explanation.

Singleton Design Pattern in Asp.net using C#

When we want to make a only one instance of a class and also making sure that there is a global access point to that object then the design pattern we user is called Singleton. The pattern ensures that the class is instantiated only once and that all requests are directed to that one and only object.

The Factory Design Pattern

Software architects generally think in terms of high-level abstractions rather than low-level programming details. Representing a system in terms of high-level abstractions promotes understanding of the system and reduces its perceived complexity. One such set of abstractions is software design patterns. They have been successfully applied in the past to simplify and solve recurring problems in software design.

Abstract Factory Design Pattern (Sample in C# and VB .NET)

An abstract factory provides an interface for creating families of related objects without specifying their concrete classes. Sometimes one wants to construct an instance of one of a suite of classes, deciding between the classes at the time of instantiation. In order to avoid duplicating the decision making everywhere an instance is created, we need a mechanism for creating instances of related classes without necessarily knowing which will be instantiated.

GOF Creational Design Patterns with C#

The GOF design patterns help address the following challenges :

design ready to accommodate change & growth

design flexible systems which come ready to handle reconfiguration and run time tailoring

code in manner to facilitate reuse during the development and extension phases ... ie. both external and internal reuse, so that we are rewarded by efficiencies as the project progresses, coming from investments made earlier in the project.

implement change in a way that doesn't overly shorten the system's useful lifespan

Design Patterns - Using the State Pattern in C#

What is the State Pattern?

The State Pattern is a behavioral pattern that can be used to alter the behavior of an object at run time. As the state of an object changes, the functionality of the object can change drastically. This change of behavior is hidden from the Client and the Client interfaces with a wrapper object known as the Context. The State Pattern is a dynamic version of the Strategy Pattern.

Need help for Architecture design


I need help to make decision for making framework for new project.
Project is financing (banking) project. It'll b using .net 3.5 sp1 with sql server 2005.
I want to know what should be best approach for framework? Mean to use LINQ or go with Stored procedure way with 3 tier architecture?
or anything else?

For current financing project the framework is done by one of MVP. He used LINQ to all things.
But we facing problem of w3wp process hang. We cant go for web gardening or farming bcz LINQ objects cnt be serialized to store in Session etc.
Difficult to use Transactions in LINQ. Have to use TransactionScope lead to MSDTC problems etc.

Please give your opinion.

database interface design question


For handy database interface, is it good to use SqldataSources exclusively intead of EntLib functions?

Thanks for any feedback.

Business object design in master details.


Hello guys, I have the following scenario,

  1. There is a master business object containing 40 fields
  2. 2 separate child business objects
  3. If I update a child record, I have to update master's 'Last modify by' status along with 3 or more fields in master
  4. For this purpose, I don't want to initialize a separate Master class object (as most of the fields are unused/wasted)
  5. The 'last modify by' also gets updated if the records in master get updated themselves

Currently I have separate business objects for master table, Child 1, Child 2 etc.

How do I control this in my business object design ? Do I break up my master object ? Say I extract last 'modify by ' into a new class, through inheritance or some other way ?

Is there a way that whenever child gets updated I use a 'small' class to update Master status only and whenever the master itself gets updated I do the same.

Problem is that I am having redundancy in my small class (Master class also contains 'Last Modify By ',

What would you advice. Please have your say. Thank you.

Edit  I am using webforms guys.

Custom Control Design-Time SiteMap Provider Error


Greetings - I was referred here by MSDN forums hope this is the right place -  

I have a custom control (:WebControl) that renders web.sitemap in a specific way. While it runs error free and produces the expected result, at Design-Time it complains

Error Creating Control - MyControl  The provider 'AspNetXmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection.

I have discovered that the error is cause by this line of code:

string div = string.Format("<div class='{0}' id='{1}'>{2}</div>", this.CssClass, this.ID.ToString(), EnumerateNodesRecursive(SiteMap.RootNode, level));

or more specifically, by the reference to SiteMap.RootNode - I am not clear what is missing thoough because I have configured the SiteMapProvider in web.config as this:

        <add name="AspNetXmlSiteMapProvider" 
             type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
