I've been looking at the MS Sync Framework today and it looks like the next
best thing in constructing data syncing between a device and the data on a
server. Started to download the Tech Preview edition and in the instructs
it tells me to uninstall any other sync bits including Sync Services for
ADO.NET. Didn't this come as part of VS2008?
I don't want to mess up VS2008. Is this MS Sync Framework a great thing?
Lost in the technical woods again....

Harry,

The Sync Framework 1.0 is a part of VS 2008, but the new tech preview
doesn't seem to hurt that isntallation in any way as far as I can tell in
early testing. In any case, the part you're probably most interested in -
the part that includes mobile device syncing - is still not available but
will be available as a tech preview or beta in a few months. I'm looking
forward to it myself.

Thanks Ginny
I was thinking that the Sync Services (?) was a subset and included in
VS2008 but that the Sync Framework was the bigger piece. Apparantly if I'm
developing a product for sale in the next few months I can't use the new
mobile connection bits anyhoo since they aren't released per se.
think we need a wise wizard to direct our use of these technologies.....as
to prioritizing them.
Thanks again
Harry

Harry,

I'm not completely clear myself where the lines are drawn between Services
and Framework, but it seems to need both. And you're right that if you need
to deploy pretty soon, the mobile piece isn't there yet so you'll have to
roll your own or use RDA, Merge, etc.

Welp I already have a RDA pull and Web service upload sync process but it is
synchronous and requires the user to wait the 11-20 seconds required to
get/give data. Happens every 5 minutes in the cradle (Ethernet) or if
wireless the user must now manually initiate.
Need a solution where the user just uses the app and the data sync is
completely transparent.
I suppose I could just wrap all that into a background thread that just
fires when it can periodically and replaces the database SDF on the device.
Problem has always been that the SDF might be being used when the new SDF is
generated so there's got to be a smooth switch of fresh(less stale)
databgase for the more stale one.

Harry,

Since SQL Compact supports multiple simultaneous connections to the database
from the same machine, you should be able to update the sdf file from a
separate thread or process if you use perhaps Web Services and read/write
the data yourself rather than using RDA. Sync Services would really be
ideal, but then we've discussed that already.

Really would not need to connect but once at a time. The local app would
use the SDF on the device for "current" data.
Looking at the Mobile Client Application block's Disconnected Application
Block too. Every messed with that Ginny?

Please note that I have nothing to offer to this thread beyond the URLs
below:

That's correct. ADO.NET Sync Services v1.0 shipped with VS2008. It is the
first step towards the Sync Framework.

Harry,

I haven't used the Disconnected Application Block in my code, but I am
familiar with it.

Hi Daniel,

Thanks for jumping in! The CODE magazine articles are defnitely worth a
