Sorry for the delay. It took some time but I managed to slap up an example source file. It’s somewhat different from the code shown above (a bit more complicated), but hopefully it will help you get around. See the update at the end of the post.

I’m trying to create a poc of your idea. On the second adapter, you only have two commands ?

Thanks

I don’t have a standalone example for this, it’s an excerpt from a big implementation, sorry… But if you can tell me what exactly is the problem, I may be able to help.

Here’s an idea that could be useful: the code I have shown above was written in the same manner as what is generated by the Local Database Cache designer (which is built into the Visual Studio). If you add a Local Database Cache item to a project, point it to a database and select a couple of tables from it, it will generate (in its *.Designer.cs file) code that is very similar to the one in my post. But, where the designer produces a single sync adapter for one table (and only for one-way replication), my solution uses two – one “normal” and one for the second pass replication. Look at the designer-generated InitializeSyncAdapters() method, it is responsible for creating adapters and adding them to the internal adapters collection. Modify this code so that it instantiates our “normal” adapter instead of the of the generated one, and add the second-pass one at the end. In this way, the normal adapter will replicate all fields except the circular-referencing ones, and the second pass adapter will come at the end and update what’s missing. (Of course, if you modify generated code and use the designer, you’ll lose your changes – so copy the code somewhere else, you may have to reconstruct the generated class a bit to be able do this).

Hope this makes any sense… It’s not a trivial task because there may be a lot of code to be written, but the code itself is not too complicated (you could modify the generated code or write your own generator for it), so it’s not too hard either.

Thanks
