Over the last few months I have been working on a little project to make Linq ‘come to life’ in two full size posters that developers can hang on the wall of their offices. The Linq posters demonstrates the usage of all Linq operators using...

CacheDictionary for .Net 3.5, using ReaderWriterLockSlim ?

In my previous post I described how to create a thread safe data cache using PFX. PFX however is scheduled to be released as a part of the .Net framework 4.0 which means we will have to wait a while before we can use this in real world applications. That’s...

Implementing a Thread Safe cache using the Parallel Extensions

Caching objects based on a key is a very common task in software development, making it both thread safe and scalable however is not quite trivial. That's why I implemented a generic implementation of such a cache, to handle the concurrency issues...

F# to ship as part of Visual Studio 2010

To be honest I don't really like to blog about stuff that is already 'out there' on the web. There are however some topics that I personally think are important and don't always get the attention they deserve. These topics mostly concentrate around parallel...

More context information in Linq queries

Last week I posted on how to use an elements sequence number in Linq queries. In the project I just finished working on, we wrote a lot of Linq queries where we needed even more information related to an elements position in the sequence, like comparing...

Selecting or filtering on the sequence number in Linq

A few weeks ago I was writing a Linq query where I needed each items sequence number (or index) as a part of the filter expression in a Where operation. To simplify the actual problem let's say I needed to filter out only the odd items. One (wrong...

More fun with Extension Methods and Lambda's: Creating a generic tree visitor

One of the most common data structures in Software Engineering is the tree. In the .Net framework for instance you can find them in the file system, the controls of a win-forms application, nodes in an XML document etc. A common task with trees is to...

Using C# 3.0 Extension methods and Lambda expressions to avoid nasty Null Checks

In the project I am currently working on we use a domain model with a quite deep nested structure of classes, code like the following is quite common. // do something with the Adress Console.Writeline(Contract.Parties.Client.Adress.Street); The problem...

Will our current programming model survive multi-core hardware?

For years the innovations of CPU's have been focused on increasing the speed at which a single sequence of instructions gets executed (mainly by increasing the clock frequency). In the last years this trend is changing from increasing sequential execution...

Lack of support for generic base classes in Windows Forms designer

Just recently having started my first real life .Net 2.0 project I wanted to utilize all the cool new features in my day-to-day job. One of those features is of course the support for Generics in C#. But, as with all cool stuff, getting your hopes up...

Timezone aware DateTime stucture in .Net 2.0 ?

The last year and a half I have been working on a project based on .Net framework 1.1, that (among other things) involved handling multiple time zones. If you have ever worked on such a project you either did it wrong without knowing or you have spent...

SQL Server 2005 vs. Office Web Components

Last week I installed SQL Server 2005 Developer Edition on a development PC. This took almost as long as installing an Oracle server, which is not what I am used to when running a 'routine' SQL Server Setup. The SQL 2005 installer starts off with...

Show source file and line number information in your Stack traces

A while ago I wrote a blog-post about not breaking the stack trace while throwing an exception up the call stack. Stack traces are the very first place you look when finding the cause of an unexpected exception. Today I was once again saved by a stack...
