How to authorize a WCF service in the anonymous internet

Wed, 24 Jun 2009 19:22:19 GMT

I had to program an authorization mechanism between a client application and a webservice that is hosted by a internet provider. In such a case, we have two different domains in place, no windows integrated authentication, no certificate or something else. The old fashioned way in that case is to use a SoapHeader in order to send informations about the user to the web service . That's the point where the trail starts .

If you start with silverlight, I bet with you that you'll get that anoying message in any case. But it has a reason why Microsoft doesn't allow that.

How to manage Control States in Silverlight Applications

Sat, 13 Jun 2009 09:28:51 GMT

In 2006 I developed a small piece of code in order to use a declarative control state handling in WinForm Applications. Three years later (2009) I thought declarative control state handling should be standard in Silverlight - but I failed. So I decided to migrate that piece of code to the new Silverlight plattform.

How to localize Silverlight Applications the smart way

Wed, 10 Jun 2009 20:05:41 GMT

A very common task when developing business applications is to localize them for english, german and other languages. The most common approach is to use ResX files in order to create resource classes which can be used to bind the silverlight controls to. Due to a bug in the resource generator from Microsoft, you always have to change the created resource class from internal to public, which is very annoying . That's why I was searching for a better solution to localize silverlight applications - and I think I found a really smart way to do that task.

Concurrent collections for C# using Parallel Extensions

Thu, 09 Apr 2009 12:11:26 GMT

One of the most difficult tasks related to concurrent programming in C# and .Net 3.5 is sharing collections, arrays or lists between many tasks running at the same time. Besides, the complexity increases when these concurrent tasks need to add and/or remove items from them. Doing this safely involves a great control of coordination data structures and the efficient use of precise locks. Luckily, the June 2008 CTP (Community Technology Preview) of Parallel Extensions to the .Net Framework added very interesting high-level coordination data structures and thread-safe collections. The result is amazing: the producer-consumer scheme complexity reduced to a minimum...

How to serialize interface types and lists using the XmlSerializer

Wed, 08 Apr 2009 16:43:31 GMT

The XmlSerializer works fine as long as you work with concrete classes. But soon as you specify an interface within an object the serialization will fail with the message "Cannot serialize member ." But there's a solution to hack this.

Using Async Delegates instead of the Thread class

Fri, 03 Apr 2009 17:17:47 GMT

If you want to write some asnychronous code, the good old fashioned way is to create a new Thread. But this has several pitfalls, e.g. when you need to use parameters or you need to retrieve a return value. Then this way is getting tricky.

Being parallel?

Fri, 27 Mar 2009 22:08:44 GMT

Doesn't today's multithreaded software profit from more cores automatically? While server software will probably show better throughput, multithreaded client software may profit from more cores, but to a far lower degree than one might think at first.

Going parallel.

Sat, 28 Mar 2009 00:16:05 GMT

The so-called "many core shift" is happening. It's not a thing of the future, it's not "just around the corner", it has already begun. And it will change our developers' life.

Reusing .NET Assemblies in Silverlight

Sat, 03 Jan 2009 23:50:05 GMT

Visual Studio 2008 doesn't allow Silverlight to reference ".NET assemblies". This document explains that there's absolutely no technical reason for this since .NET assemblies ARE Silverlight assemblies, then it shows you how to make the reference work.

Tue, 07 Oct 2008 17:13:34 GMT

When you search the web for webservice deployment you always hear: "Setup a Web Setup project ." Sure, that's the easiest solution, but not if you see it in a wider scope. So here's the manual way of deploying a .NET WebService (and it's a really simplay way)

Wed, 19 Mar 2008 15:53:48 GMT

Today I want to show how to extract data from Microsoft Excel Files. I needed it myself the time I looked for a solution to create some testdata for my application. Instead of putting the testdata into a database - which would be very hard to handle - I decided to put them into an Excel file.

How to use delegates to remove duplicated code

Thu, 07 Feb 2008 08:31:02 GMT

Sometimes you have duplicated code, that is not easy to remove with "ordinary" coding approaches. Think about the following example. You have two or more methods that needs to be encapsulated with try-catch blocks.
