James McCaffrey walks you through whys and hows of using k-fold cross-validation to gauge the quality of your neural network values.

Checking Collections and Working with Objects in Visual Studio Test

Peter looks for help in building an extension method that will let him compare two objects in a Visual Studio Test. In return, he introduces the CollectionAssert class.

Deep Focus on Your Code with CodeLens

Visual Studio 2013's new CodeLens feature provides a wide variety of information to the developer, all while never leaving the code editing window.

An API for Simple HTTP Requests

Yes, sometimes you need sophisticated libraries that handle HTTP requests asynchronously, but in other situations that can be overkill. An old Internet Explorer API may have a solution.

The Adapter Pattern in the .NET Framework

The Adapter Pattern allows incompatible interfaces to communicate. Learn how it works by building an application that calculates prime numbers.

Your guide to all aspects of how Xamarin has implemented .NET 4.5/C# 5's support for asynch operations in Xamarin.iOS and Xamarin.Android.

Windows Phone Dev 101: A Get-Started Guide for Pros

From project templates to themes to testing to authentication and much more, Nick Randolph looks at some of the tools, technologies and techniques you'll need if you want to become a professional Windows Phone developer.

Create Windows Services Easily with Topshelf

Creating a Windows Service is trivial using Topshelf, a freely-available library that converts a console application to a Windows Service. In this article, you'll create a simple notification app and integrate Topshelf.

Calling Web Services with TypeScript

Peter starts integrating a TypeScript client-side object with a server-side Web API service. Along the way, he looks at method overloading (not good), making JSON calls (good), testing asynchronous methods in Visual Studio (mostly good) and being a "TypeScript programmer."

Web API 2 Routing Attributes, Part 2

Create a Windows Store app that consumes a Web API service.

Team Foundation Server Team Rooms

Think of a Team Room as a collaborative chat workspace that records everything that happens on your team. In addition to being a real-time chat room, it also integrates with TFS to display data and interactions.

Going Beyond Usernames and Roles with Claims-Based Security in .NET 4.5

Claims-based security lets you manage your site's authorization process using any criteria that makes sense to you. And the Microsoft .NET Framework 4.5 provides some performance support for you once you start using claims-based security.

The Threat of the Stabilization Phase

Some dev organizations use a stabilization phase as a way to improve quality. But in most cases, it does more harm than good.

Essential Knockout.js, Part 2: Best Practices and More

The first installment discussed what Knockout.js is, why and how it evolved, and how it fits into Web development. This month, the discussion dives into best practices for Knockout, extending it and creating custom bindings.

Quickly populate your applications with fake names, addresses, phone numbers and much more with freely available libraries.

Building and Testing a Web API Service

As part of building a client-side application in a test-driven way and using TypeScript, Peter creates a Web API service and writes a test that proves he can access it from JavaScript code -- though there are some "wrinkles" in making this work. Along the way, he has an insight about TypeScript versus other, first-class .NET languages.

Resource Management in the Windows API

The use of constructor/destructor pairs for resource management is the most important feature that distinguishes C++ from its predecessor.
