September 30, 2008 Sep 30, 2008 09/30/08
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...

Write a NetCF app that provisions your device from your device

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 ...

Provisioning smart devices: an introduction

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.&...

Trying out the iPhone

November 7, 2007 Nov 7, 2007 11/7/07
Andrew Arnott
So I had the opportunity to try out the iPhone for a day.  Overall I was impressed, but there were some very basic features missing from many of the otherwise killer apps that I would greatly miss if I was to use the iPhone as my primary PDA and phone.  Here is a brief summary:Then of course there's the closed platform problem, and I...

November 5, 2007 Nov 5, 2007 11/5/07
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: This type would fail to serialize under NetCF 2.0 because T = string would ...

With the .NET Compact Framework 3.5 release which comes with Visual Studio 2008, a new Windows Communication Foundation transport is introduced that uses email as the communication mechanism. 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 ...
