I have been using Resx file for globalization for a long time. Now I have more than 10000 entries that are getting translated in about 50 different languages. This resx file is wrapped on a wrapper so that I can mock it during unit tests. I started noticing hit on my unit tests run time when it was taking several seconds to do mock constructor injection. My question here to the community is, is there a better way of handling globalization/localization these days? Resx has been here for a long time, I was curious if there is a better framework out there. Thank you.
