Getting the Version of an Assembly embedded as a WPF resource.

I have an assembly embedded as a resource in my application. I had the need to get the System.Version of that assembly. I figured that should be easy but off the top of my head I didn't know the series of calls needed to accomplish this. So I decided to sit down and walk through the problem. This is the thought process I went through in coming up with the solution.
I knew how to get the version of the executing assembly:

Assembly assembly = Assembly.GetAssembly(GetType());
AssemblyName assemblyName = assembly.GetName();
Version version = assemblyName.Version;

So if I could figure out how to get the Assembly object of the assembly embedded in my resources, it would be a trivial exercise. Well, I also knew how to get a Stream for the embedded resource:

Uri uri = new Uri("Resources/" + resourceFileName,UriKind.Relative);
StreamResourceInfo sri = Application.GetResourceStream(uri);
Stream componentStream = sri.Stream;

So next I had to look for a way of getting an Assembly from a Stream. Looking through the methods in the Assembly I found the promising-sounding Assembly.ReflectionOnlyLoad(Byte[]). I figured that would be useful because I knew how to get a Byte[] from a Stream:

Byte[] bytes = new Byte[componentStream.Length];
int size = componentStream.Read(bytes, 0, (int omponentStream.Length);

Then I figured I could get the assembly like this:

Assembly assembly = Assembly.ReflectionOnlyLoad(bytes);

Put it all together and you come up with this, which works!

Uri uri = new Uri("Resources/PhotoHelpDesk.exe", UriKind.Relative);
StreamResourceInfo sri = Application.GetResourceStream(uri);
Stream componentStream = sri.Stream;
Byte[] bytes = new Byte[componentStream.Length];
int size = componentStream.Read(bytes, 0, (int)componentStream.Length);
Assembly assembly = Assembly.ReflectionOnlyLoad(bytes);
AssemblyName assemblyName = assembly.GetName();
Version version = assemblyName.Version;
