Enterprise Architectural Patterns

 An architectural pattern is a common standard for an architecture and solution to a problem. Unlike Design Patterns, an architectural pattern has a broader scope and can address big problems.  The architectural pattern address various issues of software engineering, such as computer hardware performance limitations, high availability and minimizing business risk. 

Software Patterns & Practices

The article describes how to deal with Design patterns and practices while developing your application. This article is basically a pointer to all the design patterns associated with the series.

Introduction

Software patterns are there and widely followed in the industry for a long time. In Software engineering, a pattern is a generalized solution to a common problem, a software design or an architecture for a given problem. This is the widely used solution to a problem specific to an industry, a person or a goal. A Software pattern can never be identified as a silver bullet to a problem but rather it is widely accepted a solution to a problem. There could be always a notion of adjustment to a pattern to adjust the specific need of the project that is worked on by the developers. 

Patterns are essentially formalisms and naming of nice idioms of coding. It is a way to give experience to programmers. It is a nice way to know that both the developers are talking about the same thing while discussing a problem. 

Software patterns are first introduced in 1995 by "gang of four": Design Patterns by Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides. In this book, it is first discussed capabilities and pitfalls of Object oriented programming, and later on, it discusses the classic Design Patterns on OOPS. They introduced the first requirement of a software pattern while developing a piece of software in the industry. Better organizing a code is a lifelong learning experience for every developer and it is hard to follow when some functionality is needed to be implemented by a programmer. A software pattern just gives a sense of guidance to a developer while implementing a code or functionality for a problem. 

C# 6.0: Language features and its internals Part 2

As discussed in my last article on C# 6.0 features we have discussed some of the interesting features like : Auto property initialization, Expression bodied functions, Static class uses and string interpolation method. In this post, we will take the discussion ahead with more language features introduced with the new language.

The features will be covered with basic introduction to internals are :

5. Null Conditional operators
6. Exception filters
7. nameof operator
8. Dictionary initializers
9. await in try / finally.
10. Parameterless constructor for struct

C# 6.0: Language features and its internals Part 1

C# have been one of the most evolving language in recent times. It was not more than a couple of years when some of the coolest features were introduced with C# 5.0 and today we have announced the next version of C#. In this post we will try to look deep into these features and try to see what exactly is coming in the new version. I would go deeper than just demonstrating the feature so that you are well acquainted on what exactly you would be getting from these features.

1. Auto Property Initializer
2. Expression bodied Function
3. Static Class Uses
4. String Interpolation

More in Part 2 of the post.

.NET Book : Visual Studio 2013 Expert Development Cookbook

Friends, It gives me immense pleasure to tell you that my new book "Visual Studio 2013 and .NET 4.5 Expert Development Cookbook" has been released few days back. It is the continuation to my previous book "Visual Studio 2012 and .NET 4.5 Expert Development Cookbook" which has released last year. In this post, I will discuss some of the interesting parts of the book and help you understand what exactly you are expected to learn from this book. It has been tremendous effort for last 1 year which let me release this book for you. I hope this book will stand out to your expectation.

After tremendous success on my first book, presenting the next version of the book. Visual Studio 2013 enables you to develop and manage consumer-focused and business-oriented apps. It provides best-in-class tools that propel developers to create new apps or evolve existing ones. In conjunction, .NET 4.5 provides expansive capabilities for developers to work on all forms of apps and services, from client to mobile and from web to cloud, enabling them to focus solely on business logic rather than architecture.

This practical guide teaches you how to work with new changes in technology under the arena of .NET. It provides in-depth analysis and expert advice on various elements of .NET, applying them in code using detailed practical examples, and helping you understand the entire technology in easy, small steps. This book provides solutions to common development problems that you as a developer often face, thereby helping you to adapt the latest technologies as well as get grips on modern app development using .NET 4.5.

What you will learn from this book

• Get to grips with Visual Studio 2013 IDE and its various components utilizing its tools to debug your code better
• Get to grips with Visual Studio 2013 IDE and its various components utilizing its tools to debug your code better
• Understand the Windows Phone 8 development environment and gain practical experience on app development on the platform
• Create service-oriented applications using WCF and study advanced use cases on implementing a RESTful service with WCF
• Test your application inside Visual Studio 2013 IDE and advanced use case scenarios to handle testing issues
• Effectively utilize the various components of Team Foundation Server for better management of code
• Extend Visual Studio 2013 IDE to add your own custom changes enhancing your experience
• Discover the advanced usage of cloud computing with Windows Azure and its various components

Advanced Usage of Grouping in CollectionView with ItemsPresenter

CollectionView is an object that we generally use while dealing with a collection in WPF. It is an object structure that supports a collection as well some of the inherent features which a user might always need while dealing with a collection. Some of the features like Sorting, Grouping, Filtering are automatically implemented in a CollectionView.  I have written one article on how to deal with CollectionView way back in Aug 2010 which explains almost everything you need to do while dealing with collection in WPF. But it does not give the entire story.

Controls that can show a Collection in WPF is somehow derived from ItemsPresenter. The ItemsPresenter has a property called ItemsSource which takes an object of ICollectionView, and hence it is one of the important interfaces considered so far.

There are some advanced scenarios where the general Grouping or sorting does not makes sense. Here in this article I am going to deal with such advanced scenarios which might be worth mentioning.

Windows Phone 7.5 and F# - A book in the market

Hi Friends,

I am excited to announce that one of my friend cum MVP (Lohith) has written a pretty nice book on Windows Phone 7.5 using F# recently. I have given an honor to read the book from PacktPub and wanted to write a review of the same today.
