I have an ASP.NET application that uses replication, and uses the RMO DLLs to do this. I initially built the application against the 2005 version of the DLLs and have it running successfully against SQL Server 2005.
However, when I try running it against SQL Server 2008 it doesn't work. Initially I didn't deploy the Microsoft.SqlServer.* DLLs with my app - instead relying on them being in place on the server on which it was installed. However, when trying to make it work against SQL Server 2008 it was looking for the 2005 version DLLs which it wasn't able to locate.
Following some other advice I read online I have now swapped out the 2005 DLLs and referenced the 2008 assemblies in my .NET project. In my MSI I now also deploy (i.e. redistribute) the SQL Server 2008 DLLs to the bin folder of my ASP.NET project.
Now, when I try to run the application against SQL Server 2005 it fails to load the Microsoft.SqlServer.Replication assembly. I run depends.exe against this and find that it's dependent on SQLNCLI10.DLL which is missing on my machine with only SQL Server 2005 on it.
So, what am I to do? Is this possible? How do I get around this?
