That's a very strange way of using a dictionary. The alternative is simpler and significantly more efficient:
C#
public object Get<T>()
{
    if (!_storage.TryGetValue(typeof(T), out var result)) return result;
    throw new ArgumentException($"The requested view '{typeof(T)}' is not registered");
}

And the method doesn't have to be generic - you can have a non-generic overload as well:
C#
public object Get(Type viewType)
{
    if (viewType is null) throw new ArgumentNullException(nameof(viewType));
    if (!_storage.TryGetValue(viewType, out var result)) return result;
    throw new ArgumentException($"The requested view '{viewType}' is not registered", nameof(viewType));
}
