Ran Wahle — Thu, 25 Jul 2013 07:47:00 GMT

Those of you who have used signalR from it’s first version and hosted it on web application, probably know that they have to call the MapHubs extension method of RouteCollection, as shown here: protected void Application_Start( object sender, EventArgs e) { RouteTable.Routes.MapHubs(); } Those of you who has started trying out signalR version 2.0 must have noticed that the extension method has gone. Instead you have to do the following: 1. Create a class named <Hubs assembly name>. Startup...(read more)

Ran Wahle — Thu, 25 Jul 2013 07:36:50 GMT

When installing Microsoft. SignalR .SelfHost package , there was, as in any SignalR nuget package a readme file opened.

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. Negotiation phase: One of SignalR best qualities is its ability to support various communication techniques without its API user have to change his/her code. Therefore both client and server needs to “negotiate...(read more)

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 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.
