How to get the current directory on a class library?

c# asp.net path filepath configuration-files

I've been looking around but I have not found a solution for this problem: I want to create a class library that has a configuration file under a sub-directory called Configuration. I want that class library to be deployed anywhere and I want it to find its configuration files by knowing its own location.

Previous attempts with Assembly.GetExecutingAssembly().Location did not work.
It would return temp locations such as

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\7c00e0a3\38789d63\assembly\dl3\9c0a23ff\18fb5feb_6ac3c901

instead of the desired

bin/Configuration path.

So:

  1. Can a class library be aware of its own location on disk?
  2. How would I go about witting test scripts for this functionality since it seems that directories change based on how you run the app (debugging inside VS, deploying on IIS, etc)

This should work - 

string assemblyFile = (
    new System.Uri(Assembly.GetExecutingAssembly().CodeBase)
).AbsolutePath;
