Access IApplicationEnvironment.ApplicationBasePath

Question

How can I access the ASP.NET Core application base path from the property IApplicationEnvironment.ApplicationBasePath from anywhere in the code? I'm not in the Startup class but in some other helper class and I need to find the current application's directory from there. There's also no HttpContext because the method will be called independently from requests by a timer. Can I ask the dependency container or something for that information? Is there another way to get this information?

Answer 1

Always check the announcements on GitHub for the beta/rc releases.

As announced here, the IApplicationEnvrionment interface has been removed from ASP.NET Core RC2.

To get the path in the Startup method, do this

public Startup(IHostingEnvironment hostingEnvironment)
{
    var builder = new ConfigurationBuilder()
        .SetBasePath(hostingEnvironment.ContentRootPath)
    ...
}

If you need it outside, you can either use the static PlatformServices.Default method to access it's concrete types or register it with the IoC container and resolve it elsewhere. Later one is preferable for most usages.

Alternatively, use

AppContext.BaseDirectory
