A common request we get from new users of Catel is that it might be hard to understand the basics at first sight. The last few weeks we have been working very hard to provide several options for developers with every level of experience. Getting started guide For beginners, we have written a full getting started guide where the reader is guided to create a very basic application which handles the following aspects of Catel and MVVM in general: Creating a project from scratch Creating models Implementing serialization Creating view models Creating views (both user controls and windows) Additional features such as validation, event triggers and a live search function… read more →
When developing Catel, we always try to keep as much platforms supported as possible. At the time of the Catel 3.7 release, the following platforms were supported: NET40 NET45 Silverlight 4 Silverlight 5 Windows Phone 7.x Windows Phone 8 WinRT 8.0 Portable Class Libraries Starting with Catel 3.8, the following platforms will be dropped: Silverlight 4 Windows Phone 7.x The following new platform will be supported in the new version: WinRT 8.1 Recently Microsoft has officially stopped supporting Silverlight 4. They will maintain Silverlight 5 until 2021 (source). This means that Catel will no longer support Silverlight 4 starting with Catel 3.8. In a recent poll we noted that a… read more →
As you might have noticed, we brought the website of Catel to a new level of professionalism. The reason is that we want to provide a quality framework with Catel. In the past we provided quality based on these factors: Short release cycles Documentation in confluence Xml documentation in code With the new website the following new factors will be added: News and blog posts which will be updated regularly Ability to subscribe to news and blog posts via RSS or a newsletter Commercial support options News and blog posts A few weeks back, we put out a poll on how the Catel team should reach out to you.

Logging is a very important part of an application. It provides detailed information about the application workflow, even when an application is already deployed to several clients. That’s the reason that logging is a first class citizen in the Catel framework. In general, logging works by defining an ILog instance on a class: private static readonly ILog Log = LogManager.GetCurrentClassLogger(); Then in any method, logging can be added like this: Log.Info(“This is a logging with a format ‘{0}’”, “test”); Writing the Log definition can be boring and repetitive. Luckily Simon Cropp came up with a solution for that, namely Anotar.Catel.Fody. With the Anotar implementation, a reference will be added to… read more →
We are very proud to announce the release of Catel 3.7. This release took us a very long time to create and did not follow our 2-monthly release schedule. This was due to the complete rewrite of the serialization engine which needed to be tested very thoroughly. Let’s dive into the new features and most important changes. New serialization engine The flagship of this release is the new serialization engine. In the older versions of Catel, the serialization logic of the ModelBase classes was fully written in the ModelBase itself. It was hard to modify this serialization logic or to customize the behavior. In this release the logic is now… read more →
CatelR# is now compatible with the latest version of ReSharper (R#). We also keep the compatibility with the most recent R# versions including 6.0, 7.0 and 7.1. The full installer, that also includes the R# 8.0 assemblies, of the latest beta of CatelR# is available to download here. R# 8.0 includes a NuGet based Extension Manager and the Catel Team started to publish the CatelR# extension in the Extension Gallery. Yes, CatelR# is alive. We keep working in more features and also are waiting for your ideas. You got one? Let us know! So, ensure yourself to install the latest version of R# and you will no miss any of the forthcoming CatelR#’s cool features.

The Catel team is constantly looking to improve its services to its users. One of the things we think needs improvements is the way we can reach you. At the moment we only have our Twitter account in order to ask response. We think though that we leave a lot of people in the open. Below is a poll we would like you to fill in. We will check this poll once in a while to make sure that we can contact you the best ways we can:
NuGet makes the life very easy for developers. You can simply add new dependencies to projects via the package manager. However, there are some pitfalls one has to be aware of. If you are using NuGet to install Catel packages, please use this guide to update Catel to a new version. The pitfall Catel ships with many different extensions. This means that each extensions ships in its own NuGet package. This might cause NuGet packages to be installed with different versions throughout the solution. Assume the solution below: MyProject.DAL => contains Catel.Core (3.5) MyProject => contains Catel.Core (3.5), Catel.MVVM (3.5) When you go to the NuGet package manager, you will… read more →
We are very proud to announce the release of Catel 3.6! In this blog post we will explain the most important changes. To see all the changes, please check out the release notes or the issue tracker. ServiceLocator and TypeFactory improvements Circular dependency protection In this version we added circular dependency protection to the TypeFactory. This means that if there are types with a circular dependency using dependency injection, the TypeFactory will throw a CircularDependencyException with the exact type path which was used to create the type instead of a StackOverflow without any info. As you can see in the image below, when a dependency causes a circular dependency, you… read more →
You know this feeling? You are doing the best you can to prevent memory leaks by correctly unsubscribing from all events, and then you hit that object from which you cannot determine the lifetime. Well, you have a few options: Don’t talk about it, maybe your app won’t be used that much so maybe nobody notices. Try to implement IDisposable, but when to call that, you don’t know the end of life of the object? Fix the issue, but how?! Note that this solution works on .NET, Silverlight, Windows Phone and WinRT. It doesn’t matter whether you use ASP.NET MVC, MVVM in WPF of your own custom pattern. How do I… read more →
