Finding my main executable's path using Assembly vs AppDomain

Question

I\'m a .NET user, and my goal is as simple as finding the absolute path of the directory of my main executing assembly (the EXE file).

I have several candidates:

Answer 1

Use System.Linq

string MainExecutablePath= (System.Diagnostics.Process.GetProcesses().First(P =>P.MainWindowTitle == "MainExecutable'sWindowName")).MainModule.FileName.ToString();
