Andrew Arnott
The GZip encoder is not included in NetCF as it is on the desktop WCF, but it isn't hard to build yourself and in fact we have released a sample of exactly how to add your own GZip encoder to NetCF: http://go.microsoft.com/fwlink/?LinkId=108652 So many people have asked me for it lately I thought I'd better just post the link.  Have...

Andrew Arnott
My first post in the provisioning series introduced what provisioning of your Windows Mobile device means and the basics of why you would want to do it.  In future posts I'll give some concrete examples of XML that accomplish a few common tasks.  But what good are XML examples if you can't try them out on your device or emulator?&...

XmlSerializer compatibility between NetCF and the desktop

January 23, 2008 Jan 23, 2008 01/23/08
Andrew Arnott
The XmlSerializer found in the .NET Compact Framework has a very different implementation than the one found in the full .NET Framework.  The reasons for the differences include size and performance constraints that make the desktop's XmlSerializer inappropriate for devices.  As a result of the different implementation, there are ...

Using the XmlSerializer as an XmlObjectSerializer with WCF

January 18, 2008 Jan 18, 2008 01/18/08
Andrew Arnott
The Windows Communication Foundation introduced the new DataContractSerializer to replace the XmlSerializer in many scenarios.  The DataContractSerializer is faster than the XmlSerializer, but has certain limitations.  For example it does not support serializing an object's members as XML attributes.  When you write a WCF client that calls ...

November 29, 2007 Nov 29, 2007 11/29/07
Andrew Arnott
A lot of questions on the MSDN forums center around how to customize a device or an app to prefer a specific network connection over another.  The correct way to accomplish this is by "provisioning" the device.  In fact a great many aspects of the device and the applications on it can be configured through 'provisioning' the device.&...

Andrew Arnott
The XmlSerializer in NetCF 2.0 has a bug where if a single serialization requires reflecting into types that use a mixture of Collection<T>-like types for the same T the XmlSerializer will throw an exception.  Here an example where CF 2.0 would crash: public class SerializingType1 { public string[] FirstNames; public ...

Others have already blogged about this new transport including Roman Batoukov and David Kline. I'd like to take a poll of the audience to see how ...
