What version of Silverlight am I using?

I have a Silverlight application that I am maintaining. I am currently using Visual Studio 2008. I have the Microsoft Silverlight 3 SDK installed. I have Microsoft Silverlight 4 installed. When I run the application and right click on the window to pull up the about Silveright message box it tells my that I'm using 4 which is what I expect. When I open up the project file in notepad it tells me that I'm importing project $(MSBuildExtensionsPath32)\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.CSharp.targets

So I'm fairly certain that I am using Silverlight 3 when I build. Is there nothing in Visual Studio that will tell me that? I've been digging around for the big bold "You are using Silverlight Version X" property som开发者_开发技巧ewhere, but have been unable to find it.

You can only build Silverlight 3 apps with VS 2008, so if you are in Visual Studio 2008 it will be Silverlight 3.

You only get a choice of Silverlight targets in Visual Studio 2010.

The runtime is of course whatever your browser is using, but the Silverlight runtime 4 is backward compatible to runs SL 3 apps.

Hope this helps.
