Dependency Injection with Autofac

Dependencies Injection is a pattern which could be very helpful to create a maintainable and a less complex code. It is a form of IoC (Inversion of Control). The aim of this pattern is to give away the responsibility to instance some objects within own code. That means we don’t need to take care of, how, when and where we create an instance of an object. Also you have the possibility to mock up the interfaces and services in order to create unit tests. If you once understand it, you will never want to code without it again.

Customizing RTE functions according to user/role

In many cases, the customer want that some functionality in RTE are not accessible for some authors and accessible to the other. For safety reasons for example, it’s necessary to allow the Webmaster only the ability to insert links within rich text editor or to add images. In Sitecore it is possible and pretty easy to set access rights for some roles or users to read, write or edit some fields within a component.
In this article we will take a look how we could configure a rich text editor, the way that the role „User/Author“ will not be able to use the button „Insert Link“ while the Webmaster is allowed to use the „Insert Link“ button.

Create Visual Studio extensions using the Visual Studio SDK

Visual Studio plugins and extensions are kind of tools which could make our work easier and much more efficient. With the VSIX Project Templates in Visual Studio SDK, we are able to extend the functionality of Visual Studio and to create own features. Every developer using Visual Studio could implement tools according to his needs.

In this article we will create an extension, which provide the possibility to create links next to a comment in the Visual Studio Editor.
The created links are depending on configured terms and key words, which gives the developer some kind of an extended functionality to make the daily business easier and to save precious time.
We will see at first how to create an extension for Visual Studio, then how to work with this Extension.

Sitecore – Upgrade from Sitecore 6.6 to 8.2

First of all some words about Sitecore and Upgrades
When I was a beginner in Sitecore developement, the Sitecore world stands almost still for several months to years with the release of Sitecore 6.5.
So what I want to say with that is the product was more or less very stable with few small issues and no big need to update the solution for business or technical reasons.
What we did was creating wonderfull solutions without thinking to much about „how we will update/upgrade this in the future“. In my opinion Sitecore haven’t done the same in that dimension they have to do it now.
Often a Sitecore infrastructure consists of a single server instance with two – maybe three – environments (development and production) which was easy to maintain and handle.
Years go along management environements separate from delivery machines more and more, single server instances disappear in many cases to high scalable solutions with multiple servers for webapplications, sql servers, mongodb instances. Publishing instances and third party products not included.
On the other hand, we all get a little bit older: the employees searched for new challenges in other companies and you remember them only from some years ago.
