/// Call this method from the constructor of a class derived from <see cref="DbConfiguration" /> to set

/// <remarks>
/// This method is provided as a convenient and discoverable way to add configuration to the Entity Framework.
/// Internally it works in the same way as using AddDependencyResolver to add an appropriate resolver for
/// <see cref="IManifestTokenResolver" />. This means that, if desired, the same functionality can be achieved using
/// a custom resolver or a resolver backed by an Inversion-of-Control container.
