Question

I’m looking for a way to force Orchard to use a fixed language for the backend, while still being able to use the CulturePicker for the frontend.

Any hint would be highly appreciated – being my first project with Orchard I don’t really know where to start – except ugly hacking…

The easiest way would be to implement your own ICultureSelector.

You need to check if user is on admin screen first. If so, return the default site culture, otherwise return null (this way the next culture selector, in your case the one from CulturePicker, should kick in).

Example:

    public class AdminCultureSelector : ICultureSelector {
    private readonly IWorkContextAccessor _workContextAccessor;

    public AdminCultureSelector(IWorkContextAccessor workContextAccessor) {
        _workContextAccessor = workContextAccessor;
    }

    public CultureSelectorResult GetCulture(HttpContextBase context)
    {
        string currentCultureName = _workContextAccessor.GetContext().CurrentSite.SiteCulture;

        if (!String.IsNullOrEmpty(currentCultureName) && AdminFilter.IsApplied(context.Request.RequestContext)) {
            return new CultureSelectorResult { Priority = 1000, CultureName = currentCultureName };
        }

        return null;
    }
}
