It isn't very clear where you got the type library, it isn't provided as part of Windows. You can create one though. Do so from the Visual Studio 2010 Command Prompt so you'll get a .NET 4 compatible assembly. Navigate to your project directory and execute these commands:

midl.exe "c:\program files (x86)\microsoft sdks\windows\v7.0a\include\bits.idl" /tlb BackgroundCopyManager.tlb
tlbimp.exe BackgroundCopyManager.tlb

You'll now have an interop assembly, BackgroundCopyManager.dll, that you can add to your project with Project + Add Reference, Browse tab. Check the dll into source control so you don't have to repeat these steps. It isn't going to change for a long time, if ever.

Do make a note in the bug database on how to recreate the assembly, presumably this was done and forgotten the last time. That happens.

There's a new docs.microsoft.com page that talks about using BITS and C#, plus a brand-new c#/WPF sample on GitHub. These demonstrate one way to use BITS and C#/.NET
