Get version at runtime

[lonix1]

I've been using MinVer in my cake scripts to generate versioned nuget packages. It works successfully.

Now I need the version of my console programme at runtime. I tried:

Assembly.GetEntryAssembly().GetName().Version.ToString()                     // 0.0.0.0
Assembly.GetExecutingAssembly().GetName().Version.ToString()                 // 0.0.0.0
typeof(Program).GetTypeInfo().Assembly.GetName().Version.ToString()          // 0.0.0.0

In all cases I get 0.0.0.0. I get that for debug, release and publish builds.

My config includes this:

<PackageReference Include="MinVer" Version="4.1.0">
  <PrivateAssets>all</PrivateAssets>
  <IncludeAssets>runtime;build;native;contentfiles;analyzers</IncludeAssets>
</PackageReference>

Can someone spot my mistake? Thank you.

(I did read the docs, but couldn't find something applicable to my use case.)

The README states that AssemblyVersion is set to {MinVerMajor}.0.0.0, so if you are in the 0.x version range, AssemblyVersion will be 0.0.0.0.

The Version .NET SDK property, however, is propagated to AssemblyInformationalVersion, so you can use that. For example:

public static string GetVersion(this Assembly assembly) =>
    assembly.GetCustomAttributes(false).OfType<AssemblyInformationalVersionAttribute>().FirstOrDefault()
        ?.InformationalVersion ?? "Unknown";

Thanks Ralph, that gives me 0.3.0-alpha.0.5 which is what I was expecting.

For anyone else who wants to know:

// assembly version
// = 0.0.0.0
Assembly.GetExecutingAssembly()
  .GetName().Version?.ToString() ?? "unknown"   

// assembly file version
// = 0.3.0.0
Assembly.GetExecutingAssembly()
  .GetCustomAttribute<AssemblyFileVersionAttribute>()?.Version ?? "unknown"

// assembly informational version
// = 0.3.0-alpha.0.5
Assembly.GetExecutingAssembly()
  .GetCustomAttribute<AssemblyInformationalVersionAttribute>()?.InformationalVersion ?? "unknown"

I don't think the nullable items will ever be null, but better safe than sorry. However, they could be null when creating an Assembly dynamically.

"Assembly version", "assembly file version" and "assembly informational version" are defined here.
