Getting runtime version of a Silverlight assembly

I want to show my Silverlight 3 application's version number in the about box, but when I use a traditional .Net call like:

Assembly.GetExecutingAssembly().GetName().Version;

I get a MethodAccessException on the GetName() call. How am I supposed to get the version number of my assembly?

private static Version ParseVersionNumber(Assembly assembly)
{
    AssemblyName assemblyName = new AssemblyName(assembly.FullName);
    return assemblyName.Version;
}

or this: 

Assembly assembly = Assembly.GetExecutingAssembly(); 
String version = assembly.FullName.Split(',')[1];
String fullversion = version.Split('=')[1];

You can look at the js file I posted here: Detect Silverlight version required by an assembly

Your error is expected.as it is secutiry critical, above are some work arounds.

You can use

Assembly.GetExecutingAssembly()
 .GetCustomAttributes(false).OfType<AssemblyVersionAttribute>()
 .Single().Version;

GetName is marked as Security Critical and hence you get an exception when you attempt to call it.

You will need to use the FullName property and parse out the Version=x.x.x.x part of the string.
