Developer’s Guide To Collections in Microsoft® .NET, by Calvin Janes, discusses the various collections available in the built-in NET libraries, as well as the advantages and disadvantages of using each type of collection. Other areas are also covered including how collections utilize memory, how to use LINQ with collections, using threading with collections, serializing collections, and how to bind collections to controls in Windows Forms, WPF and Silverlight. For developers looking for a simple ...

I just published the BDD code for XAF. You can find it at http://bddxaf.codeplex.com. I am working on the write up of the steps to setup and use the BDD techniques described in my earlier post, but wanted to get the code out in your hands immediately. Thanks ...

The latest version of the AppFabric ServiceBus now has support for queues and topics. Today I will show you a bit about using queues and also talk about some of the best practices in using them. If you are just getting started, you can check out this site for more info on Windows Azure. One of the 1st things I thought if when Azure was announced back when was how we handle fault tolerance. Web sites hosted in Azure are no much of an issue unless they are using SQL Azure and then you must account ...

A very intriguing issue came to me to debug .Net code called from X++ code in AX 2012. This was indeed a challenge to be nailed down. Luckily the tools and some concepts helped me to achieve this task. Here it goes... We need to do a seamless debugging from AX debugger to Visual Studio back and forth. To enable this we need to first see if the dll to be debug is present in GAC then we might need to uninstall it from it due to the order of preference .NET loads the assemblies. The assemblies are first ...

I was listening to .NET Rocks episode #713 and it got me thinking about a number of SharePoint related topics. I have been working with SharePoint since the 2001 product came out and have watched it evolve over the years. Today SharePoint is one of the most powerful and flexible products in the market. Of course that doesn’t mean there isn’t room for improvement (a lot of improvement in fact) and with much power comes much responsibility. My main gripe these days is that you have to develop on a ...

Problem Normally I try to have my continuous integration as most a possible toolset free to ensure that no local stuff could have an impact to my build. My Silverlight app references a special compile target in a folder outside my developer tree: <Import Project="$(MSBuildExtension... /> So I copied the stuff from this folder to a local one and changed the call to this target in my csproj: <Import Project="..\..\..\tools\Web... ...

At my current position, I’ve been doing quite a bit of Silverlight development and have also been working with TFS2010 build services to enable continuous integration. One of the critical pieces of a successful continuous build setup (and also one of the benefits of having one) is that the build system should be able to “get latest” against the source repository and immediately build with no errors. This can break down both in an automated build scenario and a “new guy” scenario when the solution ...

If you have not developed with styles in Silverlight/XAML then it can be challenging and resources can be sparse depending on how deep you get. One thing that you need to understand is what level you can apply styles and how much they can cascade. What I am finding is that this doesn’t go to the level that we are used to in HTML and CSS. While styles can be defined at a page level if you want to share styles throughout your application they should be defined in the App.xaml file. This is of course ...

So in my previous posts I showed you how I used EDMX to quickly build my business objects within XPO and XAF. But how do you test whether your business objects are actually doing what you want and verify that your business logic is correct? Well I was reading my monthly MSDN magazine last last year and came across an article about using SpecFlow and WatiN to build BDD tests. So why not use these same techniques to write SpecFlow style scripts and have them generate EasyTest scripts for use with XAF. ...

This is what I think about Microsoft Windows Phone. If Microsoft were in our shoes looking at various phones available their configurations, memory, front facing cameras etc. Microsoft disappointed the USA customer base again by not getting Nokia Lumia 800. The Past: If we talk few years ago, few business people were on their Blackberry’s and few Gadget lovers were on crappy Windows OS devices. The world was all going right till Apple came with a revolutionary device iPhone, which completely changed ...

Today we had an interesting problem with file copying. We wanted to use xcopy to copy a file from one location to another and rename the copied file but do this impersonating another user. Getting the impersonation to work was fairly simple, however we then had the challenge of getting xcopy to work. The problem was that xcopy kept prompting us with a prompt similar to the following… Does file.xxx specify a file name or directory name on the target (F = file, D = directory)? At which point we needed ...

Files downloaded using Internet Explorer retain Internet Zone permission level and hence are “Blocked” by default on Windows 7 machines. Honestly, while an added overhead for developers; I really appreciate this feature as it provides a good protection layer for casual web users. My workaround is to simply unblock the downloaded zip file (if download was a zip file) which, in turn, unblocks the files stored within. Today however, I was left with a situation where I had to “Open” and “Copy” the content ...

Problem Normally PostSharp runs fine on unattended build servers. So on our global Jenkins continuous integration server PostSharp does the job.

Performance testing is almost always conducted to address one or more risks related to expense, opportunity costs, continuity, and/or corporate reputation. But not everyone thinks their application requires investment in performance testing.

How many extra seconds ...

I ran into a frustrating scenario today, while working with SharePoint 2010’s Managed Client Object Model. My application queries a SharePoint document library using the file’s name (the FileLeafRef field). Given that this field is unique, I was expecting only one result with the following code: 1 CamlQuery qry = new CamlQuery(); 2 3 //filter the results to only get back the item with the filename we're looking for 4 qry.ViewXml = string.Format( 5 "<Query><Where>... ...

Exerp: In this first part of the build guide series we look at building a Microsoft Windows 2008 R2 server.

In future parts of this series we will look at automating this install as much ...

Problem Our global Jenkins continuous integration server throws this error during compile step. My local TeamCity continuous integration server runs fine. What is the difference. Background I integrate some static code analysis steps via MSBuild-targets in the csproj files. To allow a fast developing without a code analysis for ever compiling I bound these targets only to RELEASE-configuration. With the MSBuild element <ImportGroup> only one condition must be specified. So my construct was: ...

So, I love how hindsight is 20/20. I love when I carefully (okay sorta carefully) write code, step through it in the debugger, check values, properly catch errors and dispose of objects and you STILL have some stupid error that humbles me a little. Yeah, welcome to my world. In fact I almost didn’t post this blog because I felt pretty foolish, but I figured if I made the mistake maybe someone else did too and I’m all about looking like an idiot if it helps someone else succeed. This is also the part ...

For good or bad, Microsoft’s Entity Framework (EF) has become one of the most widely used ORM tools out there. While some may state that it's not among the better ones (or that it's not even a real ORM), it’s definitely the most convenient one: its Visual Studio integration and consequently its integration with the MS SQL Server database is unparalleled. This is especially relevant to people who haven’t used the concept of object-relational mapping before - there's almost no initial learning curve ...

A while back read a book called the “pragmatic programmer”. Great book and I highly recommend – A section in the book was titled “Power Editing” and a suggestion they made was to have one editor. The motivation being that it is better to know one editor very well, and use it for all editing tasks: code, documentations, memos, etc. I buy into this concept – up to this point I work primarily in Visual Studio and do any other text editing in notepad or programmers notepad and while I have been able ...
