Deploying apps with database access

[Nucleus]

ok well i have made an app which attaches to an access db and it is time to create a setup package. the curious thing is that when i add the primary output to the setup package, it puts the adodb.dll, interop.jro.dll assemblies and a msjro.dll file into the application directory.

I thought the framework was all that was needed to deploy a net app? does anyone know why they are bundled as well, and where are they copied to?

what about mdac, do i need to install that too, or are those dlls all that are required?

They are installed into the application folder and yes MDAC will most likely be needed as well. By the file names I'd say you are using traditional ADODB instead of ADO.NET for your data access. If you reference any COM components, like ADODB, then it will make .NET wrappers of them and they will be required for your app to run.

If you're using ADO.NET , then I believe you don't need these dlls .
For MDAC , you can have a condition that checks for presence of MDAC if not then it would install it from the package you included (if you did) .
