Angela Henry shows how to exclude entire sections of a schema comparison in Visual Studio:
When using VS for database projects I typically use my environment specific Publish xml file to deploy changes to my local database when experimenting with code changes. However, every once in a while I will have to use the New Schema Compare tool from the Tools | SQL Server menu when I have a “one-off” database that I need to synch to my database project.
Quite frequently because these are one-off databases there will be a ton of junk items that are in the database, but not in my database project or lots of objects in my project that aren’t in my database. Either way I want to ignore those changes. In the past, I’ve always manually unchecked each item, tedious when you have more than two items to uncheck.
