How to retrieve Product Version?

Question

Is there a way to retrieve the product version of an ASP.NET 5 web application?

This is what I have in my project.json:

"version": "4.0.0-alpha1"

How would I be able to retrieve this from within the application? I used to be able to do this on older ASP.NET versions:

System.Reflection.Assembly.GetExecutingAssembly().GetName().Version

However, now it just gives me 0.0.0.0 all the time. Any ideas?

Inject IApplicationEnvironment anywhere you need the version. So for instance in the Configure method of the Startup class:

       public void Configure(IApplicationBuilder app, 
        IApplicationEnvironment applicationEnvironment)
    {
        app.UseIISPlatformHandler();

        app.Run(async (context) =>
        {
            await context.Response.WriteAsync(applicationEnvironment.ApplicationVersion);
        });
    }
