Multithreading in .NET Applications, Part 3

"Building Layered Web Applications" that shows you how to build N-Layer applications with Microsoft ASP.NET 2.0. These articles teach you how to design, build and use custom business objects in your web application. The target audience for this series are developers that are ready to make the switch from using SqlDataSource controls to ObjectDataSource controls with custom business objects. Experience with ASP.NET 2 and C# is necessary while some knowledge about object oriented design certainly helps. The design I am going to show you in these articles is a simplified version of a design you would use in a real world application. It doesn't feature all the necessary functionality your application needs, but instead focuses on the underlying concepts.

MVVM is to have an instance of a particular Model (say currentPerson) inside my ViewModel (say PeopleViewModel) which is exposed to the View (say PeopleView). The View binds and edits the Model directly.

This definitely flies in the face of what most people consider to be the holy grail of MVVM pattern, but it's a fairly new pattern, so people are still finding their way with it every day, and this works for me very well. The reason I do what I do, is for the following reasons:

1.I have always had the luxury of being able to write my own UI specific Model classes. I would even do this if I was using some other Model classes first, such as LINQ to SQL or LINQ to Entity Framework. As these classes don't have everything a proper WPF Model class needs in my humble opinion. Though, they are pretty good, as they are Partial classes and use INotifyPropertyChanged/DataContract etc etc
2.I am a pragmatist and I do not like writing code for the sake of writing code. I have seen some MVVM apps where the author has had a Model with 50 properties on it, that are simply repeated in the ViewModel abstraction, where the ViewModel added nothing. On that day I decided I would never do that unless I have to.
3.I honestly see no harm in writing directly to the Model from the View, JUST SO LONG AS if the Model is InValid its data NEVER makes its way to the database. I honestly see no pro

You can easily create services by creating an application that is installed as a service. For example, suppose you want to monitor performance counter data and react to threshold values. You could write a Windows Service application that listens to the performance counter data, deploy the application, and begin collecting and analyzing data.

This article lists the techniques that you can use to maximize the performance of your ASP.NET applications. It provides common issues, design guidelines, and coding tips to build optimal and robust solutions.

UML can be used to model a business, prior to automating it with computers. The same basic UML syntax is used, however, a number of new symbols are added, in order to make the diagrams more relevant to the business process world. A commonly-used set of these symbols is available in current versions of Rational Rose.

It is an in depth analysis of a Digg-like site and how it went from serving (on a test machine) 6 req/sec to 390 req/sec.

The biggest gain, 74 req/sec to 390 req/sec happened when he introduced data caching and another 25 req/sec where gained when he introduced the compilation of LINQ queries.

I have a WPF application that communicates with a pretty basic WCF service. Whenever a callback is issued in the middle of a request, the WPF application completely hangs. It's obviously a synchronization issue, however I've gone through the forums and articles and set every imaginable attribute on every imaginable object with no successful outcome.

In this article let us see aboutmultithreading. Multithreaded applications provide the illusion thatnumerous activities are happening at more or less the same time. In C#the System.Threading namespace provides a number of types that enablemultithreaded programming.

Threading in C#

In this post we will see how we can implement simple threading. Why do we need threading? When you want you application to do more then one thing at same time, then you need to implement threading. One usual and common scenario would be when your application needs to get data from some other resource like web services and you don't want you application GUI to be freeze during this time. In that sort of case you will run the code to access web services in separate thread so your application GUI won't freeze. The System.Threading namespace .NET provide interfaces to implement multi threading.

In order to understand completely what is a thread, how and when to useit we should first see how Windows operating system works."Windows is a preemptive multitasking operation system
