You should not resolve messages, but need to fix the root cause of the problem. Without seeing your code sample, it's hard to say anything useful.

Maciej, I really cannot see how OP could possibly fix some code using this information. I think what I wrote in my comment to the question would be all we can tell. The idea is more or less clear, but we need to know what assemblies are involved and what reference what...

Sergey, thank you for your comment.
If i understand OP correctly, the main problem is that reference to Microsoft.VisualStudio.DataDesign.SyncDesigner.SyncFacade.SyncManager is missing. He/She needs to fix it by adding it to project ;)
Let's see ;)

I add Microsoft.VisualStudio.DataDesign.SyncDesigner.DslPackage.dll
and I don't find Microsoft.VisualStudio.DataDesign.SyncDesigner.SyncFacade.SyncManager in Add Reference dialog box.
this error occurred again.
