I have a .NET solution. It contain many WEB pages, which are logically grouped into applications. When developing, I currently load/open the solution, and it's getting slow, because it's loading all the intelli-sense data, etc.. I was thinking that I could create mini-solutions or sub-solutions that reference just those files that are needed for an application. Has anyone ever done anything like this? if yes, any drawbacks, pitfalls that I should be aware of?
