I know about string embedding limit and need to switch to resources, but if PHP supports it nativelu - you sould consider generating resources on fly too.
Also refactoring 600k loc project is pure pain

I am hitting this as well trying to use MediaWiki 1.23

I see that the phalanger wiki is running on MediaWiki, so is this a regression?

jakub wrote Aug 8, 2014 at 1:32 PM runs older mediawiki (1.6.10) so I assume there are not as many string literals as it is in newer version.

This is common issue, currently the only workaround is to compile the project into several assemblies separately.
