How to use interface in this scenario

I am trying to setup interface method that will give version number:

var versionNumber = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();

I am not sure how to implement this in an interface, so that the inheriting class can get the version number?

public interface IVersionProvider
{
      string GetVersion();
}

implementation:

internal class /*or struct*/ VersionProvider : IVersionProvider
{
      public string GetVersion()
      {
           System.Reflection.Assembly.GetExecutingAssembly()
                   .GetName().Version.ToString();
      }
}

I made the class internal, because it doesn't need to be externally creatable:

public class Factory
{
      IVersionProvider GetVersionProvider() { return new VersionProvider(); }
}

Since the interface is public, external users will be able to call 'GetVersion' on it even though the implementation is private to the assembly.
