Beginners C# Tutorial
This lesson will get you started with C# by introducing a few very simple programs. Here are the objectives of this lesson:
. Understand the basic structure of a C# program.
. Obtain a basic familiarization of what a “Namespace” is.
. Obtain a basic understanding of what a Class is.
. Learn what a Main method does.
. Learn how to obtain command-line input.
. Learn about console input/output (I/O).

The ASM Method for System Design and Analysis. A Tutorial Introduction
We introduce into and survey the ASM method for highlevel system design and analysis. We explain the three notions|Abstract State Machine [37], ASM ground model (system blueprint) [7] and ASM refinement [8]|that characterize the method, which integrates also current validation and verification techniques.We illustrate how the method allows the system engineer to rigorously capture requirements by ASM ground models

Design Patterns as Higher-Order Datatype-Generic Programs
Design patterns are reusable abstractions in object-oriented software. However, using current mainstream programming languages, these elements can only be expressed extra-linguistically: as prose, pictures, and prototypes. We believe that this is not inherent in the patterns themselves, but evidence of a lack of expressivity in the languages of today. We expect that, in the languages of the future, the code parts of design patterns will be expressible as reusable library components. Indeed, we claim that the languages of tomorrow will suffice; the future is not far away. All that is needed, in addition to commonly-available features, are higherorder and datatype-generic constructs; these features are already or nearly available now. We argue the case by presenting higherorder datatype-generic programs capturing ORIGAMI, a small suite of patterns for recursive data structures.

Facade Design Pattern
definition
Provide a unified interface to a set of interfaces in a subsystem. Façade defines a higher-level interface that makes the subsystem easier to use.

Structural Design Patterns and .NET Framework 2.0
There are many uncertainties in identifying and applying suitable design patterns while designing applications. Our goal is to investigate applications of design patterns in .NET Framework. Among the seven structural patterns described by Gang of Four (GOF), we have discussed five patterns from .NET perspective. As there is no official documentation available on the patterns used in the latest version of .NET Framework (version 2.0) currently, this study would be beneficial for .NET designers in understanding patterns behind the framework, which in turn would help them in applying relevant patterns while developing their aplications in .NET Framework.
