QUESTION
Piggybacking off of a very similar question...
I need to generate an Expression from a ViewModel to pass as a search predicate for IQueryable.Where
. I need to be able to include/exclude query parameters based on what is provided by the user. Example:

QUESTION
I've been testing getting my packages up to Packagist with a simple class I made. Whenever I require it in a different project, it says the class cannot be found. Is something wrong with my composer.json autoload
