Our next beta will sport "pure" WCF client side proxies. These proxies allow the client side of a WCF conversation to seemlessly communicate with your heavier server proxies without the need for EntitySpaces on the client side. Our new client side proxies are very lightweight, strongly typed, and match your server side. The first scenario below showing EntitySpaces on both sides of the conversation is of course still possible, however, we have added the "EntitySpaces on the Server Only Model" which we will discuss in further detail now.
For those interested in our new client side proxies there is a new template that you will need to run to create them. These generated proxies would be placed in a tiny class library and used by the client to communicate with your server.
Your client side proxies will look like this, first, the collection class.
Notice that the collection is a partial class. This will allow you to add functionality if needed. Also notice that there is no link to EntitySpaces whatsoever. You serialize from your Server Side Proxy and deserialize into your Client Side Proxies. Now let's take a look at the entity class (which is also contained in the collection).
Again the single entity client side proxy has no link to EntitySpaces yet you can deserialize your heavier server side proxies into these tiny lightweight proxies on the client side. Notice the partial class definition as well. The row state is maintained for you as well. All you need to do is modify your data on the client side and ship it back to the server.
Here is a simulated converation between the server and client side proxies.
In the above sample we are serializing from the server proxy into a string which simulates your packet being sent over the wire to the client. Next we deserialize into our lightweight client proxy, change the employee's FirstName, and then ship it back over the wire to the server to be saved. The nice thing is that when you deserialize on your server you merely grab the true Employee business object from the proxy and save it, it's so easy.
From mobile devices to large scale enterprise solutions in need of serious transaction support, EntitySpaces can meet your needs. Whether you’re writing an ASP.NET application with medium trust requirements, or a Windows.Forms application, the EntitySpaces architecture is there for you. EntitySpaces is provider independent, which means that you can run the same binary code against any of the supported databases. EntitySpaces is available in both C# and VB.NET. EntitySpaces uses no reflection, no XML files, and sports a tiny foot print of less than 200k. Pound for pound, EntitySpaces is one tough, dependable .NET architecture.
