I'm looking for a way to Localize the Front End messages for Extranet.

I've created a file "Composite.Community.Extranet.nl-NL.xml" in "Composite\InstalledPackages\Localization" but no luck.

I've copied the file also to "App_Data\Composite\LanguagePacks\nl-NL" but also no succes.

What is the right way to do this?

The new file also needs to be registered in ¨/App_Data/Composite/Composite.config - open up this file, locate the -en-US version of the file, copy the xml element and change en-US to nl-NL in the copy. Then use Tools ´Restart Server in the C1 Console.

Thank you Mawtex! You saved my day, again. ;-)

We've updated the documentation. Please see http://docs.composite.net/Composite.Community.Extranet#Localization  

Thank you for pointing it out.

Would it be possible to introduce some convention over configuration? Surely, the file Composite.Community.Extranet in en-US will always be named Composite.Community.Extranet.en-US.xml, like in nl-NL will always be named Composite.Community.Extranet.nl-NL.xml.

It makes it error-prone that you need to be so explicit about things, when there is a perfectly working and understood pattern in .Net for language resources and satellite assemblies.
