Retrieving Assembly File Version from AssemblyInfo

The AssemblyInfo file defines two assembly versions: AssemblyVersion and AssemblyFileVersion. While AssemblyVersion specifies the attributed assembly version, AssemblyFileVersion instructs the compiler to use a particular version number for the Win32 file version resource, which may differ from the AssemblyVersion.

To retrieve the AssemblyVersion, you can use the code snippet:

Version version = Assembly.GetEntryAssembly().GetName().Version;

However, obtaining the AssemblyFileVersion requires a different approach. Here's how you can get it:

System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.Diagnostics.FileVersionInfo fvi = System.Diagnostics.FileVersionInfo.GetVersionInfo(assembly.Location);
string version = fvi.FileVersion;

This code fetches the active assembly, retrieves its file version information, and extracts the file version.
