问题 We have an open source media center plug-in. At the moment its download size is one measly megabyte. If I change my plug-in to require .NET 3.5, users may have to download 197 megs just to be able to use my plug-in. I am in the middle of a big refactoring process, and am aching to use some of the functional aspects of LINQ, which would considerably reduce the complexity of our codebase. Is .NET 3.5 a reasonable pre-requisite for my application? My entire user base already have .NET 3.0

问题 I'm writing an add-in for Media Center (the version that comes with Windows 7) and want to retrieve the list of physical directories which the user has included in the media libraries (pictures, videos, recorded tv, movies, music). The Media Center object model ( Microsoft.MediaCenter.* ) does not seem to have any provision to get this information. The registry has a key at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Media Center\MediaFolders , however these are always empty.
