Check the version of an assembly without loading it

I have a method which checks the version of an assembly and if it's out of date overrides it. To detect the version I'm using the following code:

version = Type.GetType(typeName).Assembly.GetName().Version;

However, if I deem that this version is out of date when I try and override it I get the following error

The process cannot access the file... because it is being used by another process.

It seems to me that the act of reflecting the assembly is causing it to load into the program and so it can't be overridden.

How can I either

  1. Check the version without loading the assembly
  2. Unload the assembly before overriding it

Consider using Mono.Cecil

which is a superior (well, pre-Roslyn) CIL assembly reader/writer.

Load the copy of your assembly in the following way.

var assembly = Assembly.Load(File.ReadAllBytes("YourAssembly.dll"));

You can now override the assembly that's on your disk.

You should just redirect assembly versions.
