Silverlight 3 just got out and already we are hearing about the new version, and this is one of the huge advantages that Silverlight has (IMHO of course), because we know that they are always trying to get more into there without sacrificing the size and the cross-browser and platform of the technology.    One of the first sneaks about the new Silverlight 4 was in Amsterdam as you can read more here , in this The Inquirer article. “(…) In an early preview of Silverlight 4 media

   When building Software as a Service (SaaS) solutions one of the things that is very important to consider is the Multi-Tenancy of the Database, and the different approaches that available in order to achieve the best option.    The option is always the same in every part of any solution, and this is from a Fixed Solution to a Fully Configurable Solution, and a SaaS solutions normally starts somewhere in the middle, that is when different customers can have different functionalities

Visual Studio 2010 is approaching rapidly from the launch and with it a new set of features will also appear. One that I think is very important is the Architectural Tools that come with this new version, and elements like: Dependency Graph Filters using Direct Graph Markup Language (DGML) on top of the generated graph. Views as: Dependency Matrix Forced Direct Layout Top to Bottom Layout   Sequence Diagrams Available on the Code Editor   Unified Modeling Language (UML) Usage of UML to

   Prism is a real interesting Guidance and was built for Silverlight 2.0, and some of the feedback I’ve received is if it works well with the new version 3.0, and so I remembered blogging about this.    The most usual questions are: 1. Does this work well with Silverlight 3 ? Yes it works fine with this new version of Silverlight. 2. Does this work well with .NET RIA Services ? Yes. They don’t only work well together, they actually complement each other, since one of the elements

   After all the information’s regarding the ADO.NET Data Services v1.5 CTP2, now the Product Team launched a tutorial in how to use this version with Silverlight from another domain and also out-of-browser. And so I think this is important for everybody that is working in Silverlight. In order to know more about the subject read this post from the Product Team .

Recently in a GASP (Grupo de Arquitectura de Software Português) we had a presentation regarding the need and the usage of CEP in solutions and the implementation presented was NESPER – Esper Complex Event Processing for .NET that is an Open-Source software available under GNU General Public License (GPL) v2. From what I saw there it’s very interesting and also not that difficult to use, but I always thought that it was strange that Microsoft was doing nothing regarding this subject that is so important

After yesterdays post about the availability of the CTP2 of ADO.NET Data Services v1.5 here are some more details regarding the Projections, Feed Customization and Data Binding. As told before Projections, the possibility of getting only the columns chosen instead of retrieving all the columns. With this we have now a new set of expressions to provide this ability on the URI, and in order to achieve we have now two new keywords available, that are: $select, allow us to define which columns we want

One of the limitations of TemplateBinding Markup in WPF is the fact that we cannot use it inside the ControlTemplate.Triggers because it really doesn’t work, since as Mike Hillberg said here , “TemplateBinding is a lightweight, but less functional, version of a Binding with a RelativeSource of TemplatedParent.  One of the things that a TemplateBinding can't do is work within the ControlTemplate.Triggers; TemplateBinding only works within the template content” . So we have this:       

ADO.NET Data Services (aka Astoria) has now the CTP2 release for version 1.5 available that will have the following new features: Projections, the possibility of getting only the columns chosen instead of retrieving all the columns. With this we have now a new set of expressions to provide this ability on the URI. DataBinding , Simplification of the DataBinding for Silverlight and WPF, because using the DataServiceCollection class we can bind it directly to the Data Service. Row Count , Ability to

As I already explained in a previous post , ADO.NET Data Services are very interesting since they generate a layer on top of our data model in a REST accessible way. Being this technology without any doubt very interesting and very helpful when building our solutions, we don’t always remember the notation that we should use in order to execute actions like: Sorting - orderby Filtering - filter Selection of only a determined set of elements – Top Ignore a set of records – Skip Make String operations
