Typical Microsoft, the usual Marketing Strategy, everything is SALEs oriented the bottom line

is products are Crude, Badly Written, full of bugs and nothing seems to work they way

they say, it is all Sale, Sales,Sales, Marketing,Marketing, Marketing, the documentation is

horrible, there is allways, I mean 100% some hidden crap you have to know or it does not work..

I am tired of Microsoft, and cant wai to see Open source to to force MS to change their ways

My opinion this Ocassionaly blah blah blah is another funky name for a very bad unreliable technology

from MS like many other things, they are MASTERs of Marketing and funcky names havent you notice?

REPLICA, TOPOLOGY......Wow, it used to be ROBUST a word they dont even know the meaning...or so it seems..

What a joke, I know you guys are gonna have to change the way you do things and come around to crearte

really usefull technology

Hello,

Did this question ever get answered. I too have a need to sync only a subset of the data. Can this be done?

I cannot see that being a problem, but to be honest I would need to try it. I makes mre sense this way because it's more efficient. I will try doing this and update this thread.

Don't know if I explained my problem good enough.(Im not english...) What I want to do is filter the data that is being synced from the server. For instance sync only rows "where userid = @MyUserId" Instead of syncing all rows in the table as in this presantation. I guess it is quite common that a client doesn't need all data from a servertable.

Very good presentation!

I have one question, I have a centralserver with lots of user specific data. And I only want to get userspesific data synced to the client. For instance if you have several salespersons and one salesperson are only interested in customerdata, orders etc for his customers. How will I proceed to sync only subsets of data?

Lookes to me like you need to use Client Application Services. With CAS you this you can acheive the granularity you require.

Hi! Great video about sync Services. I saw it when it came out on channel9. Thought I would return to the subject when any resource/tutorial/sample app including LINQ was available.

But now it's January and I haven't been able to find anything on LINQ to SQL classes together with Sync Services.

We're using mergereplication on the SQL2005 server right now.

Would love to switch to an easier approach since we're going to implement local datacahce on all our WPF client apps and take some load and traffic of the SQL2005 server when clients sorting, filtering and still using the most recent data available.

LINQ together with SyncService will allow us to stay flexible when new demands comes in from the customers.

Any tip on samples,tutorials,videos.. is appreciated.

rgds, Stanley

This will not work at present with Linq to SQL because Linq to SQL compact is not supported (yet). I create desktop applications (especially demos) using SQL compact (nice small imprint) using the SQL metal utility. This creates the necessary ORM and you can then use linq as long as you load the connection string in the constructor of the form/window you are using.
