There's one solution which is an upgraded version from VB to .Net. It's a huge project with myriad of library references to third party softwares. The other is built purely on .Net reflection(parallel framework code for concurrency and key certs for scheduled jobs). As a matter of fact there are properties for each of the solutions with dedicated assembly files, settings and resources.
The requirement is to integrate 2nd solution to first one. I managed to transfer stand alone files, without much pain into the main project. But I am not sure what my options are. How to include both assembly files into one project? How to combine the two project properties?
