My team use the Sql Server 2005 Replication feature in order to synchronize between databases in different enviornments. One of the strange things though, is that the reference to Microsoft.SqlServer.Replication generated a weird "Invalid access to memory location. (Exception from HRESULT: 0x800703E6)" Error. After a quick google search I found this link which offers a nice workaround (this seems to be VS.NET 2005 bug) which worked for several folks out there but unfortunately it didn't work for me. The search continues...
