IDictionary Options - Performance Test - SortedList vs. SortedDictionary vs. Dictionary vs. Hashtable
Please note that the advantage of Hashtable over generic Dictionary for insert and search operations demonstrated here is actually because the tests are based on NON generic IDictionary interface, so each insert or search action is accompanied with check for the key type. For more information see the Sean's comment below. (Thanks Sean!) Without that Dictionary seem to perform better than the Hashtable. The rest of the test conclusions will not be affected. This is a sequence of tests comparing the performance results for four different implementations of IDictionary and in particular generic Dictionary, generic SortedDictionary, the old non-generic Hashtable and generic SortedList. I performed several tests, comparing the following parameters: memory used in bytes, time for the insertion in ticks, time for the item search in ticks, and the time for looping with foreach in ticks. Performance Coefficient for value x = min(value 1, value 2, … value n) / value x These is the raw data.

WPF Command-Pattern Applied
Download source - 79.5 KB Introduction WPF Commanding offers the base for integration of the GoF Command pattern into an application. This article describes an approach with the following goals: Program Architecture Creation of functional units in hierarchies Reduction of complexity in large applications Automated testing Reusability of the pattern and the commands Command Description Description of a command should be neutral to the GUI in use Commands should be easy to localize Command Runtime Behaviour Static parameter (per command instance) Context sensitive runtime data Source provided runtime parameters (ICommandSource.CommandParameter) UI Integration Images and ToolTips with Gestures for existing command sources (Button and MenuItem) Visualization of a Disabled state for Button controls Selectable binding via XAML or Code-Behind Integration of existing WPF commands as for example the System.Windows.Documents.EditingCommands Command Repository Command Command Runtime Behaviour Usage

XAML Overview (WPF)
XAML is a declarative markup language. As applied to the .NET Framework programming model, XAML simplifies creating a UI for a .NET Framework application. You can create visible UI elements in the declarative XAML markup, and then separate the UI definition from the run-time logic by using code-behind files, joined to the markup through partial class definitions. When represented as text, XAML files are XML files that generally have the .xaml extension. The following example shows how you might create a button as part of a UI. Much of the material in the next few sections will be elementary to you, if you have previous familiarity with the XML language. An object element typically declares an instance of a type. Object element syntax always starts with an opening angle bracket (<). This specifies two object elements: <StackPanel> (with content, and a closing tag later), and <Button .../> (the self-closing form, with several attributes). Consider this example:
Chapter 1: Authentication Patterns
Web Service Security: Scenarios, Patterns, and Implementation Guidance for Web Services Enhancements (WSE) 3.0 Microsoft Corporation patterns & practices Developer CenterWeb Service Security: Home December 2005 Contents IntroductionImportant ConceptsDirect Authentication vs. Brokered AuthenticationAuthorization MethodsMore Information Introduction As computer systems have increased in complexity, the challenge of authenticating users has also increased. This chapter provides architectural patterns for direct authentication and brokered authentication, along with three brokered authentication design patterns that illustrate authentication using the Kerberos protocol, X.509, and a Security Token Service (STS). Figure 1. Authentication is considered to be a primary security feature because mechanisms used for authentication often influence mechanisms used for enabling other security features, such as data confidentiality and data origin authentication.
