C# – How to synchronise the publish version to the assembly version in a .NET ClickOnce application

build-automationc++clickonceversion

In my C# ClickOnce application, there is an auto-incremented publish version in the Project -> Properties -> Publish tab. I'd like to display that version in my menu Help -> About box, but the code I'm using apparently accesses the assembly Version, which is different.

The Assembly Version can be changed manually in the Project -> Properties -> Application -> Assembly Information dialog. So for now, every time before I publish I've been copying the publish version to the assembly version, so my dialog shows the current version of
the application. There must be a better way to do this.

All I really want to do is have an accurate, auto-updated, code-accessible version number.

Here's the code I'm using to access the assembly version number:

public string AssemblyVersion
{
    get
    {
        return Assembly.GetExecutingAssembly().GetName().Version.ToString();
    }
}

An alternative would be to find code that accesses the publish version.

sylvanaar's last line looks like the way to go, in my experience; but with the caveat that it is only available to deployed versions of the application. For debugging purposes, you might want something like:

    static internal string GetVersion()
    {
        if (ApplicationDeployment.IsNetworkDeployed)
        {
            return ApplicationDeployment.CurrentDeployment.CurrentVersion.ToString();
        }

        return "Debug";
    }
