We have a VS2012 solution that contains two class library projects, one that produces a Silverlight DLL and one a standard .NET DLL. The class files are shared ("Add as Link") between the two projects.
The upshot is that they both contain a WPF/Silverlight control that inherits from Canvas that we then use within Silverlight and WPF applications.
We are now looking at using the same component within an app to be used on a Microsoft Surface RT. How do I go about building a DLL that can be used like this?
