Answer 1

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. – Cyclo

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? – Muntjac

Is this still valid in .net core? – Ashworth

@Ashworth 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). – Francophobe

Answer 2

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 ! – Vernacularize

@AbdusalamElsherif where do you have the version? inside the assemblyinfo? – Woodhead

Adding the Assembly Information in this way definitely works. – Listerism

@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. – Impost

AssemblyVersion not working if you deploying using "Publish" method. – Impost

Isn't this the file version and not the package version? – Selfmoving

Using Automatic Versioning can make dealing with version numbers a lot easier. – Welter

Answer 3

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();

Answer 4

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

Console.WriteLine(version);

I don't understand why that this reply and the reply below described the same answer, but one get +17 but another get -1 – Cortege

@Cortege because is the same answer, except that 2 years after. – Deform

@Cortege You're right, I've edited the other answer to clean it up a bit. It's more valid than this answer, which is just a dupe of the top-voted answer. – Hunch
