Hosting WCF service in Windows Service

When building Windows services we often need a way to communicate with them. The natural way to communicate to service is to send signals to it. But this is very limited communication. Usually we need more powerful communication mechanisms with services. In this posting I will show you how to use service-hosted WCF web service to communicate with Windows service.

Webcast: Brief introduction to Windows Identity Foundation

This is my first webcast on Windows Identity Foundation (WIF) and it will give you brief overview of this technology. I will tell you about how I found WIF, what is claims-based authentication, what tools are available and how you can use WIF in your systems. This is no-code overview and you can expect demos and code from my next WIF webcasts.

Programming Windows Identity Foundation

Programming Windows Identity Foundation by Vittorio Bertocci is right now the only serious book about Windows Identity Foundation available. I started using Windows Identity Foundation when I made my first experiments on Windows Azure AppFabric Access Control Service. I wanted to generalize the way how people authenticate theirselves to my systems and AppFabric ACS seemed to me like good point where to start. My first steps trying to get things work opened the door to whole new authentication world for me.

WCF: The maximum message size quota for incoming messages (65536) has been exceeded

When using WCF services you may get the following error: “The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.” This error is given because of size limits set to responses in your application configuration.

Making asynchronous calls to web services during ASP.NET page processing

Some ASP.NET web applications use web services to get some data that they display to users. Some pages may lay hardly on web services and these pages need some optimization to work better. In this posting I will show you how to use web services behind your ASP.NET page asynchronously and perform a lot of queries to web services. Sample code included!

Example workflow to request songs from radio station

Today I played with WF 4.0 declarative workflows. This posting shows you simple workflow that you can extend to add songs to online radio station queue. My main focus here is workflow and I will provide here no logic for actual queue implementation. You can find here also Visual Studio 2010 sample solution.

Using WCF Services with PHP

I recently wrote two postings on the subject of WCF services: WCF Services – Let’s Get Started and WCF and Unit Tests. One could see that creating and testing services was not complicated at all. Let’s go on and take some steps nearer to the real world – our service is used by SOAP clients running on different platforms.

WCF and Unit Tests

Good practices demand tests for every new thing you have been able to get running. Otherwise our TDD chief is glum and moody during smoke breaks. So, to maintain the ever cheerful and busy climate in our office, this posting is going to discuss testing.

WCF Services – Let’s Get Started

In connection with testing WCF services I had to get the services to work under IIS on my development computer. The default WCF services library created by Visual Studio does not automatically include IIS support. There were other small glitches that I was able to overcome nicely, in spite of everything.
