EntitySpaces - WCF DynamicQuery Serialization

Sun, 14 Jun 2009 03:46:43 GMT

We have decided to use the WCF DataContract approach when serializing our enhanced DynamicQuery's. In our upcoming alpha release our DynamicQuery classes now live in a separate assembly that can execute on the client side along with your EntitySpaces proxies without requiring either the EntitySpaces.Core or the EntitySpaces.Interfaces assemblies. The EntitySpaces.DynamicQuery assembly (only 52k in size) is also compatible with Silverlight and can run down inside of the browser.

Can you Query me now?

EntitySpaces 2009 Q2 is going to revolutionize your ability to use the EntitySpaces 2009 architecture on the client side of any two-way conversation, whether it be a Silverlight, WCF, or a webservices conversation. In fact, you will be able to work on the client side as if the full EntitySpaces architecture was at your disposal but without actually requiring the EntitySpaces architecture be present on the client. "But how can that be?" you wonder. Continue reading and we will explain.

How to serialize SubSonic objects with nullable properties

Wed, 04 Feb 2009 07:27:31 GMT

Recently, I ran into the following error when trying to serialize some SubSonic generated classes. "Cannot serialize member 'XXX' of type System.Nullable`1[XXX]. XmlAttribute/XmlText cannot be used to encode complex types." The SubSonic autogenerated classes cannot serialize nullable types such as DateTime? and GUID?. This is really a .NET serialization problem and not directly related to SubSonic, since the SubSonic library just uses the native .NET code for serialization. I'll describe 3 (or 4) different ways of getting around this problem.

One important reason why your Code Generation tool does not get used

Sat, 24 Jan 2009 20:39:53 GMT

Just-in-time Code Formatting is the process of changing the formatting of any code to the way you want it. Imagine I send you a small project, you open it and find I have prefixed all fields with an underscore. Your development tool, understanding this as a problem, changes the variable prefix for you when you open it. It lays out the code the way you like it. and likewise, when I open it, its changes the way I like it.

EntitySpaces 2009 - Running under Visual Studio (Part 2)

Fri, 31 Oct 2008 10:46:03 GMT

In this post we'll take a look at both the Template Browser and the template user interface mechanism. The Template Browser lists the templates in a tree based on each template's Namespace located in the template header (shown left). You can see from the TemplateInfo tag in the template header that there is both a Namespace and a UniqueID attribute. The UniqueID will be discussed later when we dig into the user interface. Now, however, let's take a look at the Template Browser. The Template Browser is shown below (while running under Visual Studio).

NHibernate objects dirty on load with nothing set in between

Wed, 15 Oct 2008 00:56:48 GMT

While easy to do, an incorrect mapping file can have you ignorantly firing off multiple updates to a database when flushing your session. This post demonstrates, and reminds you to watch how you've mapped your enums.

EntitySpaces 2009 - Running under Visual Studio

Fri, 17 Oct 2008 01:46:09 GMT

EntitySpaces 2009 will plug right into Visual Studio and it will use its own internal code generator. This means that Visual Studio users will never have to leave Visual Studio to work on or generate their EntitySpaces architecture. The image below shows how EntitySpaces 2009 looks embedded within Visual Studio. While it is likely to change a little before our first beta this should provide you with a feel for ES2009. The nice thing is that ES2009 is a dockable window just like any other window within Visual Studio, you can even generate your EntitySpaces classes directly into your solution and the folders/files will be created automatically for you.
