Access the assembly version using Assembly.GetExecutingAssembly() and display in UI

Assembly.GetExecutingAssembly().GetName().Version.ToString();

Thanks for your time, It works but always set the version 1.0.0.0 although my application version is 1.0.0.158 ! – Abdulsalam Elsharif May 04 '14 at 20:21
@AbdusalamElsherif where do you have the version? inside the assemblyinfo? – Sajeetharan May 07 '14 at 03:55
Adding the Assembly Information in this way definitely works. – csmith Mar 04 '16 at 03:03

@AbdulsalamElsharif, i think this is because you are using this code snippet from another project(another assembly). For example your main Windows-app version is 1.0.2, but your dll-project is 1.0.0. – Vladislav May 18 '17 at 10:11
AssemblyVersion not working if you deploying using "Publish" method. – Vladislav May 18 '17 at 10:18
Isn't this the file version and not the package version? – Mike D. Jan 10 '19 at 13:50
Using Automatic Versioning can make dealing with version numbers a lot easier. – SezMe Aug 01 '19 at 18:16

Add reference to System.Deployment library to your project and adjust this snippet to your code:

using System.Deployment.Application;

and

string version = null;
try
{   
    //// get deployment version
    version = ApplicationDeployment.CurrentDeployment.CurrentVersion.ToString();
}
catch (InvalidDeploymentException)
{
    //// you cannot read publish version when app isn't installed 
    //// (e.g. during debug)
    version = "not installed";
}

As stated in comment, you cannot obtain publish version during debug, so I suggest to handle InvalidDeploymentException.

If you start by checking ApplicationDeployment.IsNetworkDeployed this will let you know if CurrentDeployment is available. This way you don't have to handle the exception, but can make a simple if-else. – aliceraunsbaek Aug 13 '16 at 09:24
This answers half of the question, but not the part about displaying it in the WPF display. How do you bind a component to then use this version variable? – njminchin Aug 08 '18 at 06:32
Is this still valid in .net core? – hybrid2102 May 04 '20 at 07:34
@hybrid2102 It works well. I used these codes on WPF .NET Core 3.1. I added text, Version 1.1.1.1, to Project -> Properties -> Package Tab -> Package Version. I can get the right string on runtime (includes Debug). – cmcromance Sep 16 '20 at 01:41

Use GetEntryAssembly rather than GetExecutingAssembly to get the version from the current executable rather than from the currently-executing DLL, like so:

string version = System.Reflection.Assembly.GetEntryAssembly().GetName().Version.ToString();

string version = Assembly.GetExecutingAssembly().GetName().Version.ToString(); 

Console.WriteLine(version);

@Smith.Lai because is the same answer, except that 2 years after. – Erre Efe Apr 10 '18 at 14:07
@Smith.Lai You're right, I've edited the [other answer](https://stackoverflow.com/a/44134308/2288578) to clean it up a bit. It's more valid than this answer, which is just a dupe of the [top-voted answer](https://stackoverflow.com/a/23459838/2288578). – Clonkex Feb 03 '22 at 23:22
