SignalR Protocol

Ran Wahle — Sun, 17 Feb 2013 20:24:00 GMT

SignalR Protocol After showing how to get started with SignalR , how to use it with .Net client and how to self host it, I wish to show what SignalR does on the network level. In this post I will review the protocol SignalR implements and see what data is sent at the various stages.

About embedded & external resource files

Ran Wahle — Tue, 05 Feb 2013 14:13:00 GMT

About embedded & external resource files Recently I was asked by a colleague of mine to help him with a problem. He had tried numerous times to work with resource files on a web project and got many errors until he had moved the files build action from content to embedded resource. What’s the difference? Embedded resources are files that are put inside the compiled assembly when compiling it. However, when a resource file build action is content , only the .designer.cs file that comes...(read more)

Self Hosting SignalR

Ran Wahle — Sun, 20 Jan 2013 10:58:00 GMT

Self Hosting SignalR SignalR , as shown in the earlier posts, can be hosted within a regular ASP.NET application (in other words, on IIS), but can also be self-hosted. You may want to do so if you don’t want the SignalR hosting machine to have IIS installed. In this post I’ll show a simple way of doing so with a console application. It won’t be much different with windows service and I’ll explain how to do it there as well. Step 1: Install Nuget packages There are two nuget packages...(read more)

Programmer’s Backdoor Trap

Ran Wahle — Tue, 31 Jan 2012 16:58:00 GMT

Today I’ve encountered something that made a programmer happy but made me sad. He had to pull data out of Data Warehouse and use it for his system. Later, he was informed that DWH personnel made his life easy: They’ve decided to write the data into his own database so he wouldn’t have to work so hard. Unfortunately this news made him happy, and therefore he went on with it, which made me even sadder. ...(read more)

KnockoutJS–Dependencies

Ran Wahle — Mon, 05 Dec 2011 13:53:00 GMT

KnockoutJS–Dependencies One of the things we’ll probably need is to be able to have dependency tracking in our bounded data. For example – if we have a customer’s list, we’d like to see the customer’s orders whenever we click on a customer. In this post I’ll demonstrate how to do it using the dependentObservable function of KnockoutJS Let’s look at the following JavaScript code: var viewModel = { customers: ko.observableArray([]), selectedCustomer: ko.observable(), orders: ko.observableArray([])...(read more)
