Silverlight and local singleton

Is it possible for multiple instances of a Silverlight application running on the same local computer to get a hold of a local object instance on that compputer.

I'm thinking about having a WCF service hosted 开发者_JAVA技巧as a window service on the local computer which hands the Silverlight applications the singleton object to use. But I am not sure if it's a good solution or possible at all.

Your solution is good. If you don't want to do all sorts of hacks in silverlight calling COM objects your idea is the right way to go.
