How do I determine what version of Silverlight an assembly is compiled against?

Given a assembly how do I determine (in code) what version of Silverlight that assembly is compiled against?

So I want a method that does this

public static decimal GetSilverlightVersion(string assemblyPath)
{
   Magic goes here
}

and it should return 2.0, 3.0 or 4.0

Note: the executing code is .net 4 not Silverlight

The compiler embeds the [TargetFramework] attribute into the assembly. You can read it back at runtime with reflection. Some sample code:

        var asm = System.Reflection.Assembly.GetExecutingAssembly();
        var attr = asm.GetCustomAttributes(typeof(System.Runtime.Versioning.TargetFrameworkAttribute), false)
            as System.Runtime.Versioning.TargetFrameworkAttribute[];
        if (attr.Length > 0) {
            label1.Content = attr[0].FrameworkDisplayName;
        }

Displayed value on my machine: "Silverlight 4".
