MEF is based on 3 keywords: export, import, compose. Since these 3 words all start with a letter that can be combined to a word, and MEF is cool, here’s a hint on how to remember it: MEF is cool as ICE!

I hope most of you are by now aware that in .NET 4.0, there have been some major changes made in Windows Workflow 4.0. Most of the activities of WF 3.x are now changed by new activities. In this article, we will see how a workflow can be designed using procedural activities, how input arguments can be specified in a workflow and how a hosting application can pass these input arguments. We will be using Beta 1 release of VS2010, .NET 4.0.
This article explains following activities of WF 4.0:
- Sequence Activity.
- IfElse activity.
- InvokeMethod.

Forms are usually seen as that obnoxious thing we have to markup and style. I respectfully disagree: forms (on a par with tables) are the most exciting thing we have to work with.

Here we’re going to take a look at how to style a beautiful HTML5 form using some advanced CSS and latest CSS3 techniques. I promise you will want to style your own forms after you’ve read this article.

At the heart of Branch-Per-Feature, is the notion of using source control in a manner that allows multiple teams or individuals to work on the same software system without clobbering each other with change sets. That is, we should be able to work in a manner that allows Feature Team A (FTA) and Feature Team B (FTB) to work independently of each other. FTA should be able to analyze, code, test, and deliver their feature without any regard for the work that FTB is currently engaged in. When either team is finished with their work, the other team will merge the now stable feature changes into their branch, and continue on from there.

At a very high level, all branching strategies have the same core policies: create the branch when you are confident that the cost of branching and merging is less than the cost of committing to the main source line, and merge when you are “done, done” making changes in that branch. There are many branching strategies that are very useful. You can branch per iteration or sprint, branch per sub-team, branch-per-release, branch per feature or defect, etc. Most likely, though, you will find yourself in scenarios where a policy of a single branching strategy is not feasible. The real world is full of fun surprises and little nuances that can make a single strategy good, bad or otherwise – all within the same project.

Branching and merging are never free operations. Even if you are using a source control system that makes the mechanical process of branching and merging negligible, there are other costs that need to be accounted for than just the button clicks or commands that are required for a developer to commit changes.

People keep saying that Entity Framework is simple to learn. Simple? Well, finally, we're going to be forced to agree, thanks to James Johnson's new series on learning EF the 'hands-on' way.

Every good developer knows never to re-invent the wheel, especially if there is software out there that has been tested by others, and has an established track record. As a developer using the .NET framework I’ve found some of these libraries invaluable, so I’m sharing them for some of the other dev’s out there with a brief outline of how to use.

Key Points discussed in this article are : 1. Include SET NOCOUNT ON statement 2. Use schema name with object name 3. Do not use the prefix “sp_” in the stored procedure name 4. Use IF EXISTS (SELECT 1) instead of (SELECT *) 5. Try to avoid using SQL Server cursors whenever possible 6. Keep the Transaction as short as possible 7. Use TRY-Catch for error handling

Firefox is the browser of choice for most designers and developers in part because of the vast selection of add ons that are available. While Chrome does not offer anywhere close to as many extensions (yet), there are still a number that can be very handy for designers and developers. In some cases they are not as robust as the Firefox versions (example, Firebug and Firebug Lite), but if you are using Chrome you may be interested to know about the extensions that are available. Additionally, Chrome comes with some developer tools built in.

In this post we’ll feature 17 of the most useful Chrome extensions for designers and developers. Hopefully in time the selection and quality of Chrome extensions will be able to rival those of Firefox.

During our everyday programming tasks we run into several repetitive code blocks that after the 20th time you implement them become really annoying. The worst case is to re-implement these code blocks every time, and the better case is to create a central class library with helper classes and methods. However, a large amount of these tasks can be achieved easily with built-in .NET methods.

C# 4.0 biedt nieuwe mogelijkheden die het de ontwikkelaar in een dynamische omgeving makkelijker maken. Dynamic programming is het sleutelwoord en stelt de C# ontwikkelaar in staat om eenvoudiger samen te werken met dynamische talen zoals IronPython en IronRuby. Naast dit dynamic programming kent deze versie van C# optionele en benoemde parameters, betere integratie met COM. Andere vernieuwingen in C# 4.0 richten zich op multicore en declarative programming. In dit artikel wordt met name de features van dynamic programming onder de loep genomen en zie je hoe ze in de praktijk kunnen worden toegepast.

This guide covers the association features of Active Record. By referring to this guide, you will be able to:
* Declare associations between Active Record models
* Understand the various types of Active Record associations
* Use the methods added to your models by creating associations

Associations are a set of macro-like class methods for tying objects together through foreign keys. They express relationships like "Project has one Project Manager" or "Project belongs to a Portfolio". Each macro adds a number of methods to the class which are specialized according to the collection or association symbol and the options hash. It works much the same way as Ruby‘s own attr* methods.

An important part of software projects is documentation; this includes end-user documentation and technical documentation. The latter usually includes API documentation, which is important for developers working to maintain or extend existing software. There are a number of large-scale API documentation repositories, including, but not limited to, the Java docs and MSDN.

Such documentation can be done within your code, in the form of comments. You can then use a tool to extract those documentation comments and convert them into other formats such as HTML or CHM.

As we close the book on 2009, I want to remind you that at the beginning of each year, you have an opportunity. An opportunity to step your game up to the next level. An opportunity to branch out from the same, hum-drum development you've been doing for the last 5 years. This article is a list of possible New Year's resolutions for you, as a developer, to consider. I'm not suggesting you try to achieve all of these, rather I want you to pick one, and commit to it for 365 days. Write it down and stick it your monitor. Keep it in your wallet. Most importantly, keep it on your mind.
