I've been experimenting with the Package Manager, specifically with the PostProcessing package. Previously, my generated Visual Studio projects contained source code for PostProcessing (since it was in my Assets folder). This allowed me to use the Visual Studio text search tools to find code in PostProcessing another packages I'd installed in my Assets folder. However, using PostProcessing from Package Manager, I noticed that Visual Studio text search tools no longer work. It appears that Unity Package Manager packages do not appear in the Visual Studio project at all anymore. Is there anyway to include the packages in my project like before? If not, is there another project that I can open to at least search each package individually?
