Odious ambiguous overloads, part two

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

"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.

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.

Multithreading is a powerful design tool for creating high-performance applications, especially those that require user interaction. Microsoft .NET has broken down the barriers that once existed in creating multithreaded applications. The last two installments of the .NET Nuts & Bolts column were

This post covers one such feature which is Routing in Webforms. Although Routing was available even in .NET 3.5 SP1, (check this excellent post by Phil Haack on implementing Routing in ASP.NET 3.5 with .NET 3.5 SP1), it was kind of less known. Also the plumbing work was too much for getting it implemented.

This article give you a brief description on the new features of C# 3.0 and make our life easier.

This will reduce number of steps of code writing.

In this first part of the two part series, Steven covers the differences between Site and Application pages in SharePoint 2007, why each may be used in various circumstances, and prepares for the construction of a menu located application page. After a brief introduction he examines the concept of Site Pages and Application Pages separately in detail with supported screenshots.

As the second article in a two part series, Steven examines the attributes and details of a SharePoint 2007 application page, including the construction and feature deployment of the same page based project. Since this is a WSS level objective, as opposed to MOSS, you will not need MOSS to work with the code included in this project. Windows Server 2003, WSS, and Visual Studio 2005 are all that is needed, with no additional add-ons. He provides a detailed analysis of each step involved in the creation and deployment of the project.
