Smart Device and .NET Compunication

[Prateek]

Hi,

We are developing a new project in which it has to talk to smart
devices. Some of the smart devices are running on Windows CE 3.0 OS and
some of the smart devices are running on Windows XP Embedded OS.

Now the solution which we are proposing must be compatible with both
devices and I am facing a problem in communicating the application on
Windows CE 3.0 OS withn the .NET Web service.

Following is the solution which I am proposing but finding difficulty
in communicating the application in Windows CE 3.0 with the web service

1 - A new web service is created running on the web server
2 - Each application running on either Windows CE 3.0 or Windows XP
Embedded OS will invoke the web service hosted on the web server

Now I need some help on this, if any one can.

1 - On the smart devices running on Windows CE 3.0, do we have to
upgrade the OS to 5.0 or CE.NET?
2 - Do we need to install the .NET Compact Framework on all the smart
devices whether running on Windows CE 3.0 or Windows XP Embedded OS?
3 - How application on smart devices running on Windows CE 3.0 or
Windows XP Embedded OS will communicate with the web services. I belive
..NET Compact framwork doesn't support Remoting and hence web service
cannot be used so what could be the alternative way?

It would be very much helpful if anyone can help me on this or provide
some pointers.

Thanks

Prateek

1. Windows CE 3.0 is not supported by any version of NETCF, so yes, you'd
need to update to CE 5.0 (or 4.2).

2. XP runs full .Net framework, CE runs Compact Framework (NETCF).

3. NETCF does not support remoting, but it supports Web Services. Remoting
has nothing to do with WS. You can also use MSMQ or sockets instead of WS.
