.NET Application - Fetching Assembly/File Version confusing

Question

I want to read the version info of a Strong Named .NET (built using v4.0) assembly using Powershell v2. I am using two different ways to do this, but the 2nd method always gives me the correct version information [although the 1st method was the obvious natural choice] :-

Method 1: [Reflection.AssemblyName]::GetAssemblyName("C:\ManagedAssembly.exe").Version.ToString()

gives the value as "50.0.0.0"

Method 2: [System.Diagnostics.FileVersionInfo]::GetVersionInfo("C:\ManagedAssembly.exe").FileVersion

gives the version correctly as "50.0.0.93"

Any idea why such a behaviour ?

How do you know that the above is wrong? Windows Explorer on Win 7 doesn't show the assembly version by default and instead shows the file version. Your two values for file and assembly versions look sensible. — row1

Assembly Version and File Version can be set different in solution properties from Visual studio. — CB.

Got it. I just opened the AssemblyVersionInfo.cs file and observed the following entries - [assembly: AssemblyVersion("50.0.0.0")] & [assembly: AssemblyFileVersion("50.0.0.93")] --- which makes sense. — Angshuman Agarwal

+1 for the OP for using [Reflection.AssemblyName]::GetAssemblyName which gets the version info without loading the assembly into the current app domain. Most examples use [Assembly]::Loadxxx(), which can be problematic. — piers7

My Mistake & Ignorance. The AssemblyVersionInfo.cs file contains two entries -

[assembly: AssemblyVersion("50.0.0.0")]

&

[assembly: AssemblyFileVersion("50.0.0.93")]

So, the above code is absolutely fine.
