troubleshooting a .NET/WPF 4.0 application requiring 2.0 to run

discovered an interesting error recently while working with Microsoft's Collaborative Application Markup Language (CAML) that, surprisingly, had received no ink. Partly what surprises me about this is that the error may require you to rewrite large sections of your code if you haven't previously considered this SharePoint limitation. I'll start with some context, but first of all the error is:

This month we will continue with the theme of deploying Microsoft's SharePoint as a company intranet by describing a method for integrating a legacy Web application inside a SharePoint site.

In many companies the intranet site is not just a home page with announcements. It houses Web applications used by many different departments. In last month's article, I built a page to search the employee table in Northwind (the sample database included in Microsoft's SQL Server). This month, I will move the Web pages used to add/remove records from the table into the SharePoint intranet.

The Model-View-Controller (MVC) pattern separates the modeling of the domain, the presentation, and the actions based on user input into three separate classes [Burbeck92]:

Model. The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller).

View. The view manages the display of information.

Controller. The controller interprets the mouse and keyboard inputs from the user, informing the model and/or the view to change as appropriate.

It has always been a goal of project architects to plan an effective strategy from the ground up in regards to an new application. All relevant factors are taken into consideration with respect to the application, from its design and layout to a functional website infrastructure. Pre-.NET strategies and design guidelines still effective now were developed with Microsoft's DNA (Distributed interNet Application) platform. This model successfully served the purpose of architecting N(any number of)-Tier (levels) applications. In its basic sense, as in most robust, distributed applications, you'll architect 3 main layers or Tiers: presentation, business rules and data access.

Application Architecture is the most important process of developing a good application. Some people tends to jump into coding without any architecture laid. Later we see those people changing the architecture and finally the application had to be developed from the scratch with the correct architecture.

In this article I will describe some details about how you can improve the architecture of you application. This article is targeted to the beginner's audience.

Application performance has always been a concern for Web Application developers. This article contains guidelines and tips for maximizing application performance in ASP.NET.

In the arena of application development, developers all over the world use various programming languages, technical processes, and technical tools. While using number of technical & non technical elements the processes or methods become complex, for simplification of the application development process, developers use various techniques such as dividing the application architecture into layers or parts. In the professional & technical language this separation or division process is called N-Tier Application Development process, where "N" stands for number and "tire" stands for layers or parts.

As you know that in 3 tier architecture there are three layers

User interface layer. (Is our Form in Windows application and .aspx page in Web application)
Data Access layer. (Which provides interface between Business logic layer and Database)
Business Logic layer.(Which stores your application logic)

The article describes Lightbox as, "... a simple, unobtrusive script used to overlay images on the current page." It delivers a nice, professional looking method for displaying images as overlays through the use of hyperlinks.

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.

Applications have special support in Windows Forms. For starters, you can manage and tailor your application's lifetime, and, when the work flow is disrupted by an unhandled exception, you can choose from several methods of response. Then, there are several application models that you can employ, including Single Document Interface (SDI) and Multiple Document Interface (MDI) applications, each of which can support either multiple-instance or single-instance mode, the former the VS05 default and the latter requiring special consideration. All applications, however, can discover and use a wide variety of information about the system and environment they execute in.

Consider an MDI application like Microsoft Excel; files opened from the file system (by double-clicking) are all opened as separate child windows within the parent Excel window.7 For the first instance of an MDI application to open a new child window to display the file that was passed to the second instance of the application, the second instance must be able to communicate with the initial instance.

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.

SharePoint has two types of ASPX pages. One type is the application page, also known as a _layout page. The other type of ASPX page is a content page, also known as a site page. Each of these page types is stored in a different location in SharePoint. When developers create custom ASPX pages, they must decide on the page type.

This month we will continue with the theme of deploying Microsoft's SharePoint as a company intranet by describing a method for integrating a legacy Web application inside a SharePoint site.
