JavaScript for Line of Business Applications

As a .Net developer Visual Studio is my greatest power. This robust, adaptable and powerful IDE provides everything I could possibly need. 
But with upcoming new JavaScript technologies like Node and Single Page Applications, it sometimes falls short. It's not that Visual Studio is bad for creating JavaScript applications, but it could do better. 
AngularJS intellisense support is a good example of a missing feature, as it is neither included in the Visual Studio core or in the Web Essentials extension.

Connect to Twitter from a mobile application using OAuth with the Xamarin.Auth library, along with Joe Mayo's LINQ To Twitter library.

For these set of examples, we'll use OAuth as a mechanism to authenticate users. We'll authenticate users, get a response and display information to the user (specifically, a profile image). From there, the example will integrate with Twitter via OAuth and then make calls to Twitter via a third-party library. This will demonstrate the strength of the growing Xamarin ecosystem.

Mark Michaelis walks you through the Visual Studio tooling and project setup you'll need to get the most out of your JavaScript unit testing.

Of all these characteristics, it's JavaScript's lack of type safety coupled with not having a compiler fail in the capacity to verify intent. That is, of course, if you don't have unit tests. Unit tests can compensate for the lack of type safety. And unlike with .NET, where unit tests focus mainly on functional verification (since the compiler eliminated the majority of typos), unit tests in JavaScript do both. In summary, JavaScript unit testing is all the more critical because it's responsible to not only verify functionality, but also to verify syntax and language semantics.

In this article, I'm going to focus on the Visual Studio tooling and project setup requirements needed to get the most out of your JavaScript unit testing.

Presentation explaining asp.net MVC4 including what's new, explaining how it works and finally implementing a real world application.

It’s been known for some time that Anders Hejlsberg was doing something interesting in the JavaScript space, and when Anders is doing something interesting, it’s worth paying attention. This is, af...

You my friend, cannot ignore JavaScript no longer, JavaScript is the most deployed language on earth, a beautiful and expressive language that supports many paradigms and which has a thriving community that continuously expands and improves its ecosystem with patterns, libraries, frameworks and tools. You don’t want to miss this train.

But JavaScript, though forgiving and specially conceived to be easy to learn, can be either daunting for us that have a strongly-typed mindset baggage and come from languages such as C# or Java or even more often laughed at as a toy.

Tomasz Janczuk has created Edge.js, which allows users to combine the power of .NET with Node.js. Curious about how to add non-blocking communication to your .NET project? Looking for a way to move computationally intensive code out of your Node thread? Janczuk's article provides a great starting point on how Edge works and the benefits it can bring to your next application.

* Powershell

Use a T4 template to generate Knockout-viewmodels based on .NET classes.

This article describes a solution to this problem by using T4 templates to generate the JavaScript Knockout models automatically based on the .NET classes. The resulting Knockout models are extendable so as to be able to add additional functions and (computed) properties client-side. Finally, I also added an IsDirty feature that can indicate if the model has been modified since it's data was set.

Project Liike is an effort to produce guidance that helps organizations build mobile web experiences based off of existing web applications. There are countless devices available today and all indications suggest this number is only going to grow, without convergence. The factors to help choose between native apps and web apps are fairly well-known. Those who choose the web face numerous decisions and challenges based on their requirements. This project aims to help.
