I have a Visual Studio 2008 solution with several projects. One project is a web site with a Target Framework of “.NET Framework 3.5”. One is a Silverlight 3 Application which was created with the selection (in the dropdown) of “.NET Framework 3.5”.
I notice that if I wish to add a reference to System.Core.dll to the website, I am presented (on the .NET tab) with a single choice of version 3.5.0.0, which seems perfectly reasonable to me.
If, however, I drop and re-add a reference to System.Core within the Silverlight application, I am only presented with System.Core version 2.0.5.0. What’s the story here? I’d very much like to use some of the methods of TimeZoneInfo that [I infer] are only available in .NET 3.5 sp1. What am I missing?
TimeZoneInfo isn’t available to Silverlight – you need to use the 2.0.5.0 .NET assembly version (Silverlight).
