Enterprise applications need good architecture to survive ever-changing demands of customers. At same time these systems must be stable, convenient and easy to use which leads us to need of good architecting skills. Some customers need desktop applications while others need web-based and mobile applications. Making good architectural decisions is not easy and this is where brilliant book Microsoft .NET: Architecting Applications for the Enterprise by Dino Esposito and Andrea Saltarello comes in. (more…)

Finding out reason of bug in code is not always easy thing to do. But it can be extremely hard if you have no idea what do with information that exceptions provide you. In this posting I introduce you weird artistic handling of exceptions and unfortunately this story comes from real life.

One of soon-to-starts projects uses linear programming for some optimizations. As it is not very familiar topic to me I started looking for examples and tools so I am prepared better when action starts. In this posting I will show you how to solve simple linear programming tasks using Microsoft Solver Foundation – free math package available by DevLabs.

NLog on is popular logging component for .NET applications. I am using it in one project where I built multi-threaded server that is running similar threads with different configuration. As those thread are independent services I needed way how to configure NLog to create different log file for each thread. Here is my solution.

I’m building web application for customer and there is requirement that users must be able to import data in different formats. Today we will support XLSX and ODF as import formats and some other formats are waiting. I wanted to be able to add new importers on the fly so I don’t have to deploy web application again when I add new importer or change some existing one. In this posting I will show you how to build generic importers support to your web application.

It is often good idea to isolate our domain model from consuming applications by using service layer and data transfer objects (DTO) or application specific models. Using DTO-s means that we need two-way mapping between domain classes and DTO-s. In this posting I will show you how to use AutoMapper to build generic base class for your mappers.

In this posting I will show you how to use Task Parallel Library (TPL) and PLINQ features to boost performance of simple RSS-feed aggregator. I will use here only very basic .NET classes that almost every developer starts from when learning parallel programming. Of course, we will also measure how every optimization affects performance of feed aggregator.

I solved a little problem last night when playing with named pipes. I created named pipe that writes all output to file. Named pipe is opened for all users in machine. In this posting I will show you simple class that works as pipe server.

For Windows Home Server 2011 (WHS) there are new API-s available you can use to extend WHS web and desktop interfaces. Actually there is no Windows Home Server SDK anymore – now we have common Windows Server Solutions (WSS) SDK that works also for Windows Small Business Server, Windows Storage Server and Windows MultiPoint Server. In this posting I will show you how to create development environment for Windows Home Server 2011.

When using Jira web service methods that operate on work logs you may get the following error when running your .NET application: Object of type System.Xml.XmlNode[] cannot be stored in an array of this type. In this posting I will show you solution to this problem.
