Allow to embed precompiled razorviews (or any other webviewpage) Things that would be nice to have in Microsoft's code: - public access to VirtualPathFactoryManager.Instance - public access to VirtualPathFactoryManager.PageExists - let either store IVirtualPathFactory just the Type to construct instead of a constructor, or: let DictionaryBasedVirtualPathFactory use IoC if it's registered - allow to override BuildManager implementations, that way we could hook into the framework on that level, instead of creating an extra viewengine
