If you need it you should probably post a question on Microsoft's sync framework forum. But if you want the debugged version, take a look at the comments above, there's a couple of links to download the updated versions with full source. Hi,

Is the above “sql express provider source” link working? Thanks in advance.

It has an enhanced version of the Express provider which doesn't use a guid table so my question earlier is likely yes it is not necessary when using change tracking. It is curious that the SyncAdapters are created on the client instead of in the service as I have done withe my SQLCE implementation. I see how there could performance benefits when doing this if using an adapter builder because you don't have to make a remote call, but it also limits the functionality to have data driven filters and filter parameters. I'll play with it some more to see what I can work out. Anyone else out there trying to use dynamic Adapter builders with an Express client? 30) I was able to get the sample code working no problem.

I assume the "source" link in the blog has all the integrated changes. I've just started converting a SQL 2008 Server with CT to SQLCE product to use an Express client and let me tell you the process of getting there has sucked. I am using N-Tier and have been asked to do it without modifying schema or using triggers. I found your page from an answer to my question on Stack Overflow by JuneT. A combination of damon's sample and William M's client have me almost fully functional. My variations is that all syncadapters are created with the builder. I do however have a question. Neither the server or client DB script has a reference to the "guid" table. Is this not needed with CT or am I missing something? Also, I would like to know if there is any new advice on this process since 9/2010 from William M.

Unfortunately, a couple of comments seem to have disappeared from the WordPress database - the site was moved to a new hosting service but I don't think that's what caused the problem. I'll see if I can reconstruct them somehow. Sorry about that.

It appears as if some comments were lost after it came back. I currently have no issues with any topic that have been uncovered here. My solution is now (again) available at that link above should anyone be interested. This website was down for some time. It appears as if some comments were lost after it came back.

Am really happy with the provided code for SQL Server - SQL Server client/server syncing - thanks for going to the trouble of publishing it. But I've reached a point now where I want to enable batching of the updates... Documentation seems to be a bit thin on this, so was wondering if/how it can be implemented in this scenario...? Seems to be related to a class called DbSyncContext - where is that? I can't seem to find where it fits in...? Any help would be really appreciated. Thanks. Hi guys.

The logical solution is to lock the table through-out the sync, but that could be rather costly during proxy-trips to a remote server, rendering the db useless during that time. (and we're talkin about multi-user client support so...) The other solution I am playing with is persisting the possible "rogue" changes between the upload|download phases to xml. And during the next sync, push those changes before applying the rest of the changes. I do not "love" the solution, but it does seem to be solid. (if anchor state is lost you have to re-init, which is the way the entire system works anyway, this just stores more data in the event that a table is updated mid-sync) So alas, no solution complete today. Tomorrow I will continue. 20) I was correct, this will work fine so long as you use brackets around your table name. NOTE: you have to use the brackets in your anchor table as well as it is string comparison. 21) This functions just fine. 18) This is proving to be a much more complex beast than it would appear.
