Building Spotify remote control service with ASP.NET Web API and SignalR

Because there are also single user use cases for the ASP.NET stack!

I have just published a new article over at my friends from Tech.pro (who have revamped their site this week too, and it looks awesome!). It’s my third one there, and once again we look at utilizing ASP.NET Web API, SignalR and bits of Knockout.JS.

This time, however, it’s all single-user, as we will try to create a service that would allow you to remote control your Spotify client over HTTP. This, I believe, is quite unique, and hopefully it will highlight an interesting use case for this technology stack. As you usually, the source code is on GitHub.

Head over to Tech.pro to read the tutorial, and I hope you’ll enjoy it!

The future is now – OWIN and multi-hosting ASP.NET web applications

Different frameworks, side by side on the same port

As you probably know, the ASP.NET team is publishing the latest ASP.NET Web API on a nightly MyGet feed, and you can grab them from there and play with the latest stuff without having to deal with all the hassle related to building from the source.

The same applies to Katana, a Microsoft generic Owin host, which also has its own MyGet nightly feed.

Let’s glimpse into the near future and have a look at putting the latest Katana bits to play with ASP.NET Web API and other frameworks.

Collaborative route planner with SignalR, Knockout.js and Google Maps

Today I have published a new article over at my friends from Tech.pro. This time, we continue on the topic of SignalR & Knockout.js, and look at implementing a real-time collaborative route planner with the use of Google Maps API. Hopefully you’ll enjoy the article as much as I enjoyed writing it.

These libraries, really make a lot the development tasks feel like true magic!

As you usually, the source code is on GitHub.

Shopping cart with SignalR, ASP.NET Web API and Knockout.js

Because real time is cool!

I have published an article at Tech.pro today, about building a real-time shopping cart with some of our favorite technologies – ASP.NET Web API, SignalR and Knockout.js (or, as Brad would say, with the “Webstack of Love”).

SignalR, Filters and ServiceStack

I recently blogged about a technique of integrating SignalR with ASP.NET Web API through the use of action filters.

A few people have asked, whether this approach (and SignalR now being part of Microsoft’s ASP.NET product group after all) works with other frameworks. And the answer is absolutely yes.

Let’s have a look at implementing this for ServiceStack.

SignalR, ActionFilters and ASP.NET Web API

Because if something is reusable, move it out of controller

There have been quite a few examples circulating on the web on how one would use SignalR together with Web API. It all started after Brad Wilson had a great example on calling SignalR from API controllers at NDC Oslo 2012.

Even on this blog we looked at calling SignalR from Web API ITraceWriter to provide realtime tracing capabilities.

How about, to avoid any controller-level noise, messaging the connected SignalR subscribers from ActionFilters? While this approach might not be applicable in all scenarios, when it is, I think it could provide a nice layer of separation.

More after the jump.

Realtime ASP.NET Web API tracing with SignalR

Because with SignalR, everything can get really exciting

The latest ASP.NET Fall Update, released recently, introduced the Web API tracing package into the Web API core. It is the default implementation of ITraceWriter, built around the System.Diagnostics, allowing you to easily trace what’s going on inside your API and output that into the debugger’s console.

On this very blog, we discussed a similar approach a couple of months ago already, by building an NLog powered trace writer for your Web API.

Today, let’s take all this a step further, and build something much more exciting – a realtime Web API trace, powered by SignalR.
